Original review: Sept. 5, 2020

I thought I’d write a review because you never hear from all the people who’ve had good experiences. This medication has helped me to achieve what I have been desperately trying to accomplish for over 10 years. Like so many people, i began to gain weight in my 30s after having children, and tried everything to stop the weight gain. I ate healthy, tried every diet, I ran 5-7 miles per day 5 days a week, and I just kept gaining weight. For me, it was clearly something other than lifestyle that was causing it.

Eventually my doctor suggested Phentermine. The first effect I noticed was loss of water retention. Two days in, I had dropped 7 lbs (I would have to imagine that was water) The following week, I lost an additional 2 lbs, and have continued to lose an average of 2lbs/week since. I am now a few months in, and about 30 lbs down. Aside from the obvious metabolism boost, the phentermine has helped me to eat smaller portions, and most importantly, curb the desire to eat late at night (which as we all know, is the absolute worst thing you can do if you want to lose weight!) When I know I shouldn’t be eating (after 7pm) I can have a cup of tea, and be ok with it. Before phentermine, I would be completely miserable when I got hungry at night. Of course, there’s still that element of self control, but the phentermine makes it so much more tolerable!

For the first time in a long time, I feel like I look great! I have about 10 more lbs I’d like to drop, and then I’ll stop the medication. I am hoping that my eating habits will “stick” for 6-12 months, and when I notice things slipping (which I’m sure they will, because that’s life) my doctor is happy to do “maintenance” weeks with the phentermine to help keep my habits on track. I think the key will be to stay aware of my weight and of my eating habits, and when I notice things trending in a bad direction, immediately start a maintenance week, before the bad habits set in. My doctor has had a lot of luck with patients doing this and keeping the weight off long term.

In terms of side effects, I absolutely have more energy, and had to completely cut out caffeine. The first couple of weeks I was jittery, but have adjusted since. Made the mistake of drinking coffee once, and will never make that mistake again- it was wayyyy too intense! I have taken anxiety medication for years, but could absolutely see that if I did not take anxiety meds with the phentermine, it would make me anxious and probably irritable. If you are a naturally anxious person, I would definitely talk to your doctor about pairing the phentermine with a low dose SSRI. Aside from that, the only thing I have noticed is dry mouth, which makes me drink more water, which I honestly should be doing anyway, so good for me!

Overall, I don’t think I could be more happy with the results I have experienced so far. Everyone responds differently to medications, and from reading other reviews, it is clear that phentermine is just too strong for some people. Personally, this medication has been such a blessing. It has helped me to look the way I did in my 20s, which I thought was never going to happen for me. I would absolutely recommend it for people who have tried healthy eating and exercise, but have a stubborn metabolism. Phentermine will not do the work for you, you still have to make good choices, but phentermine can make the process a whole lot less miserable!

I started taking Phentermine on Jan. 6, 2020 after I weighed in at over 211 lbs. at a doctor's appointment - more than twice what I weighed when I got married! I take 1 pill in the morning on an empty stomach and, other than a headache, which is relieved with **, I have not had any negative side effects. I will say, though, that at the same time I started the phentermine, I also began a Weight Watchers program to help with my eating habits, and I joined a fitness center to tone and tighten the areas where I was losing the weight. I began this journey weighing 211.4 lbs, and I am now down to 166.8 lbs. - almost 45 lbs. in exactly 5 months. My biggest secret? When I feel that the phentermine isn't curbing my appetite as well as in the beginning, I go off of it for a month, then go back on. It's working!

Updated on 11/04/2020: This is a follow up on my initial review on Phentermine that I published in May 2020. I was 183-186 lbs in May and for 3 months I was able to go down 20 lbs. After month 3 the medication stopped working.

Original Review: I have been fighting with weight-loss for 10 years now. I was able to lose some on a keto diet but never kept it off. It got to the point where I hit 183 lbs. I am 5'2. Two days ago I was prescribed Phentermine. I was so afraid from the side effects that the nurse suggested to cut the full dose pill in 4. So I am taking roughly 7 mg. a day. Immediate side effects are dry mouth, frequent bathroom visits, insomnia and a mild headache which may be the product of no sleep. I had to take melatonin 5mg so I can go to sleep around 3 am.

First day I felt a little weird as if I had a mild hangover but today that is gone. Energy levels have increased. I am a little high strung but I hope that will go away after the first week. I have no interest in food whatsoever. I am on 11-7 fasting and low calorie diet but only ate 600-700 hundred calories on the first day out of 1200. And I had to force myself to eat by dinner time. I will get fiber gummies since I feel constipation might be an issue too. The nurse advised me to not increase my dose if the 7 mg. works for me.

Today I took my second dose and weighed myself and I am down to 179 lbs. My guess is that is water weight. I drank 7-8 bottles of water on the first day. My goal is to go down to 145 lbs. in six months and hope that diet, healthy eating habits and some form of exercise will get me there. I don't want to rely on the pill. I will follow up with an update in a few weeks.

Original review: April 22, 2020

I have to say Phentermine worked right on Schedule as I needed to lose weight for a total knee replacement. I started on keto October 2018 and weighed 243 lbs and was 48 at the time and I'm 5'2". I have arthritis in both knees. October 2019 I lost 10lbs on my own with keto and several inches so I was feeling really good. The same month I found out I had no cartilage in my left knee and needed surgery but needed to lose more weight so my doctor started me on 15mg of phentermine which I only lost 2 lbs that month then in November he put me on 30mg of phentermine which I lost 4 pounds that month and in January 2020 he put me on 37.5mg phentermine and that weight melted off and I lost another 11 lbs, February 10, 2020 I had to stop taking phentermine and all meds to have surgery on the 27.

So for 3 weeks I stopped cold Turkey taking phentermine and still lost an additional 3 lbs on the day of surgery. They weighed me before it and I weighed in at 211 lbs. So in total I lost 22 lbs on the three months I was taking phentermine and it was all done with no exercise which I didn't do due to the severe knee pain before the surgery. In all it worked very well for me. Now I exercise mildly as I'm still recovering from the surgery which today's date is 4/22/2020. It's been 8 weeks since the surgery and I plan to continue to exercise to keep the weight off. Phentermine was a beneficial aid for me and I plan to keep off the weight it has helped me take off and I hope I never have to use it again.

Okay so here’s my experience, it’s the most honest description I can give. So I heard about this pill from a coworker and she gave me the info to get it. I got a month supply and was told to only take it for 3 months. So I got excited and started with day one.. Felt awesome hardly any appetite.. Was very thirsty and drank a lot of water. Day 2 same thing.. Day 3 felt that I had to use the restroom but I was constipated still hardly any appetite and a severe dry mouth. Day 4 still wasn’t able to poop and my mouth was getting itchy and dry and my eyes were itching and had tingling in both my arms and feet.. They were also cold cold. Day 5 had the worst headache of my life but didn’t think anything of it. Still wasn’t able to poop when I knew I had to!

Day 6 headache still wasn’t gone my left side went numb and my heart was feeling exhausted and I was catching my breath every 10 seconds... Day 7 same thing as day 6 and headache got more severe. Day 8 now. This is when I did my research about this drug and read everyone’s different experiences on here.. Some were all similar to what I was feeling.. I got so angry and depressed and couldn’t even focus at work... My heart was pounding very fast/I couldn’t sleep my head was pounding/my legs were stone cold. My arms were tingling - my mouth was dry and made me have a bad breath/I was not able to hold any liquid down or food. I would go throw it up... I stayed in the restroom trying to poop and couldn’t. It felt like a lifetime :: the next morning I threw them all away and said hell no!!!!

I’m still recovering from this and I’m so scared. Never again am I going to take the easy way out. It is not worth it!!! This will mess you up mentally and physically!!!! Do it the old school way. Exercising and eating right!!!! Stay away from this. I’m glad I was able to stop immediately and it only took 8 days for my health to deteriorate. By the way I opened the capsule and it all white dust. Who knows what is all mixed but it’s deadly.

Original review: March 28, 2020

Powerful. I started with 1/2 dose then quickly went up to 1 full dose. In the beginning, it does give you an energy boost and makes you talk and want to move around a lot but it does not help with concentration. Slowly I started to feel no effects and was hungry despite the pill. Dehydration is a big negative as well as cotton mouth. I forgot to eat often and the lack of food led to confusion. Then when I ate I felt like it wore off.

After awhile taking it didn't make me less hungry so I stopped taking it. It feels horrible coming off of it. Nausea, anxiety, twisted stomach, baggy eyes, gag reflex a lot. I started taking 1/4 dose and felt like it was easier on the side effects but again stop taking it and detox was bad. You're not supposed to drink with this stuff and trust me, it's not a good idea. You can drink more but you become super dehydrated and overall feel like ** the next day. Overall, if you start this I suggest starting with 1/4 of the prescribed dose and be careful to know the side effects when you come off.

Original review: March 22, 2020

I had about 30 lbs to lose, went to a weight loss clinic near me and the doctor recommended Phentermine. I was taking it for about a month and started to notice hair loss but I didn't put two and two together at first. I decided to go online and found out that phentermine causes hair loss although the doctors never tell you about this side effect nor is it listed on the bottle as I would never have taken it if I knew. I took it about two and a half months before I found out and stopped taking it immediately. My hair is very thin and I have started taking many vitamins, etc.to try to get it back to normal. I believe the doctors don't tell you about this side effect on purpose because they know that many women would not take it if they knew this. I will never take it again. I also had heart palpitations, dry mouth and constipation. This is a terrible product!

I believe taking Phentermine causes multiple sclerosis. After taking Phentermine for a month my daughter lost vision in her left eye. I rushed her to the hospital because she's only 25 years old. Was diagnosed with MS. She has never had any type of medical problems prior to taking this medication. I would give this product no stars if I could.

Original review: Dec. 21, 2019

Would rate a zero if I could. I went to a dr regarding my difficulty losing weight. I am 49 and despite by regular activity, the 30 lbs I need to lose don't budge. He prescribed me Phentermine - 15mg when I wake up and 15 mg an hour after breakfast. I started 8 days ago and up until last night, the only side effects were dry mouth and staying up later than normal. In the middle of the night last night I woke up feeling off balance, just rolling over I felt off. I sat up and the room started to spin over and over. What felt like an eternity, only lasted maybe 15 seconds (15 seconds too long for me).

I called my dr who said that vertigo is a side effect and to cut the dose in half. I also called the pharmacy. They said for the short time I am on it there is no need to wean off, so I am DONE with this pill. They say there is no magic pill and it's true. I praise those who have found weight loss success, but at what cost? I am otherwise healthy with a beautiful family. I am sorry I brought myself to a low point to rely on a pill to "fix" what I should do by eating better. DO NOT TAKE IT. NOT WORTH THE PRICE OF YOUR HEALTH.

Original review: Dec. 4, 2019

I feel like Phentermine has ruined my life. I'm a 27 year old female and other than being overweight, I have always been healthy. I complained to my doctor about not being able to lose weight so he sent me to a weight loss clinic and they prescribed me phentermine 37.5. Day 1, I had dry mouth, a lot of energy and no appetite. I thought it was great. I was barely eating and drinking almost a gallon of water a day. Day 2 and 3, same side effects but now I couldn’t sleep. I decided to take half a dose for Day 4 and 5 and was finally able to sleep. I continued taking the full dose on Day 6.

By Day 9, I had lost 11lbs and I was ecstatic. But that was also the night I ended up in the ER. My resting heart rate was 180. I was shaking, pale and my lips were blue. I honestly thought I was going to die. They did blood work, and EKG. Both came out fine. I was told to stop taking the medication and that things would get better. Things did not get better. I was told to follow up with my PCP 2 days later but was unable to because of Thanksgiving. I had to wait 6 days before going to my doctor's appointment. During those 6 days of waiting - EVERYTHING I DID ELEVATED MY HEART RATE. Walking would make it go to 130, getting dressed 150, walking up stairs 165. Even laying in bed it would sometimes go up to 120. I literally was scared to get out of bed until my follow up appointment.

I finally was able to go to my PCP. They performed another EKG. It was fine. But he was concerned he heard something in my right lung and feared it was a blood clot. He sent me to the ER again. I spent the day getting every test done, blood work, xrays, EKGs, ultrasounds. You name it. They did it. Every test came out perfectly fine. They sent me home. But still, everything I do elevates my HR. I am exhausted, feel like I cant breathe and it feels like someone is sitting on my chest. I am terrified to do anything because as soon as I do my HR goes up. I am suppose to follow up with my doctor in another 2 days. I was told if it doesn’t improve I may need to get on medications to control my HR.

Had I known this pill would cause all of this harm I would have never taken it. I wanted a shortcut and easy way out. And now I dont even feel like myself. Please just try to eat healthy and work out, slowly but surely. Ive done it before and regret not trying to lose weight the healthy way again because now I can barely even walk without feeling out of breath. I’ve been off of the medications for 7 days with no improvements. If this review can stop anyone from taking this pill I will be happy it saved someone.

Original review: Nov. 12, 2019

I started taking Phentermine 6 months ago I was losing weight really good. My last month changes started to happen. I was enraged at everything. I felt like a balloon about to burst. I've never felt that way before. I became withdrawn and has mood swings. I wasn't sleeping. My heart was pounding. My mouth was dry and so were my eyes. I had to have a colonoscopy and they told me to stop taking the meds 5 days before I did. When they hooked me up to the monitor I was told my heart was beating resting 125bpm and they were going to have to give me medication to slow it down that I could have a stroke or heart attack that scared me half to death.

I looked it up when I go home and it has its own name Phen-rage?? I read on about it and I believe it to be dangerous. It was the other half of the ** back in the day that many women died young from heart disease. I don't think it's worth the damage to your body trying to lose weight just get yourself on a diet plan and exercise. I'd never ever take these again or any other diet pill. Read up before you take this. Has I know the side effects I wouldn't have taken them. I stopped them immediately and have slowly come back. Please read Phen-rage you will see how dangerous this medication is.

Original review: Oct. 3, 2019

First time writing a review- but I have found them so helpful so I think this may help someone else. I am 53 and 5’7” 165 pounds. My goal weight is 139 (want to under 140) and BMI goal is between 21-24. In work out every day for 45 minutes of cardio. I have been on the low carb and no sugar bandwagon for nine years and it has kept me at the same weight after losing 30 pounds and changed my life and health completely. However with the hormone changes, I suddenly gained 20 pounds and hadn’t changed how I eat or my workout routine. Very frustrating. I am in good health and take no prescription medication. I went to a weight loss and hormone clinic to deal with menopause symptoms and weight gain as a result.

I was prescribed 37.5 mg of Phentermine with the idea of taking only half to start. I want to tell anyone who starts this journey that each person is different and dosage sensitive. You have to play around with times and dosage to find your sweet spot for being effective and diminishing the side effects. I had terrible insomnia, dry mouth, heart palpitations, and constipation. Was told they would go away. I stopped after three weeks because the insomnia became a deal breaker. Symptoms went away. Fast forward three months and I started reading all the verifiable reviews- all 33 pages. Also the new research on low dosage (8-10 mg) Phentermine and it’s effectiveness and FDA as well as medical approval after clinical trials. This was important to me.

I cut the 37.5 mg into 1/4 pills. Not easy but with tablets you can do it. Ask for tablets not capsules. I take it right when when I get up at 6 am. It has been two weeks. I still had insomnia even on this low dose for three days. I started taking 10 mg of ** and that did the trick. Still had minor dry mouth but it’s fine because I drink a lot of water. I switched to decaf green tea in the morning. Still had some constipation issues so started Metamucil (sugar free) in the morning. Again, this works. No heart palpitations. Still have energy and very diminished appetite. Have lost 8 pounds. This can work and can be safe if you work with your sensitivity to it and push through minor side effects. Not for everyone if you have serious side effects, then reconsider. Good luck to everyone.

I’m a 30 year old female, I was 57 lbs over the weight I wanted to be. Started Phen in 7/2019 and now, 10/2019 I took my last pill. It’s been exactly 3 months today. So far I’ve lost 28 lbs. It did not fall off like it did for some people. I did change my diet and workout more. I didn’t give up Alcohol and I feel like that was the problem for me. I didn’t drink much but I had a drink every now and then. Side effects: dry mouth, tremors (after 2.5 months) and chest pain (at 2.5 months). Not even sure if the chest pain is related but I ended up in the ER and they filled everything else out so it has to be that.

I have another month of the pills let but I’m going to give myself a month off to see if I can lose weight on my own or at least keep the weight off. I’m scared I’m going to gain it all back. I’ve been reading reviews about people who did but they didn’t exercise while on the pill. I’m at the gym everyday. Overall, I am very satisfied and would recommend it as a boost to get your weight loss started. I’m so mad that my chest is hurting the way it is though. Other than those two side effects, I haven’t had any issues with it. I didn’t lose nearly as much weight as I wanted to or thought I would but I’m happy with where I’m at. Everyone is different so base your decision off what you and your provider talks about. Anyone who writes a review who has had the very health conditions that they say don’t take the pills with is ridiculous to say they don’t recommend. Just be smart about it, listen to your body and make smart decisions.

Phentermine is meant to be used in conjunction with diet and exercise. If you can put all three together for a month or two, you'll see some results. The key is to learn to exercise and eat properly while on the diet. Because when you stop using Phentermine, your appetite will come back in full force. If you have a balanced diet and a solid exercise routine when you stop, then you should be able to maintain the results.

For men, the side effects can be brutal. I suffered from high libido but also erectile dysfunction. Your genitalia may shrink some. Just these sexual health changes alone are enough to cause mental health issues. That's not including increased blood pressure, dry mouth, etc. If you are at a point where you are close to your goal weight, and can stand the side effects the drug may cause, they definitely go for it under the supervision of your doctor. It definitely can help.

Original review: Sept. 24, 2019

Got this after 2 years of chronic neck pain and migraines that prevented me from working out. I was very active and when I started getting medical issues I was unable to work out as much but I was continuing to eat without burning off those additional calories. Gained over 50 pounds which made my medical issues worse so my Dr. prescribed **. I did get headaches for the first 3 days then took half of pill the 4th day. With half of pill I still had cravings so the 5th day took the whole pill and my headaches subsided. Side effects for me were constipation but I took fiber gummies and that helped. Also insomnia. I usually slept 8 hours but on this I slept 5-7 and couldn't fall back asleep. It did help with energy and I was more motivated work out.

Lost 16 lbs the first month, 13 the second month and I'm on my last month right now hoping to lose at least another 10. You MUST adapt to a healthy lifestyle and exercise. This is not a miracle drug where you take it and still eat crappy. Don't take it and still eat McDonald's and not exercise. Because it's a stimulant you will have more energy and if you just sit around then it will cause you to be jittery. I think the cravings will come after my 3 months but I am hoping my body is less hungry since I have been used to eating smaller portions. Overall ** helped me start getting my life back.

My first day taking Phentermine. I had it at 6am, fell back asleep, woke up at 730am, no symptoms. Went to work, feel fine but talked a lot more. It's been 9 hours since and I feel fine, mouth is not dry at all, no dizzy spells, no heart palpitation,s did sweat when I started to clean up. I had a power nap and don't feel starving I could eat if I wanted to but honestly can't be bothered making anything so I'll see how I feel in the morning. All I had today was peanut butter toast for dinner.

Original review: Sept. 12, 2019

I’ve seen so many negative reviews I felt compelled to write one (I never write reviews). At 43 yrs old I was 5’6” and weighed 145 lbs when I fell 6’ off of a ladder and, among other things, tore my ACL and broke my tibia. My injuries had me pretty much immobile for months and thanks to the injuries, combined with a move to a new state and depression, the weight started packing on. Within a year I gained 78 lbs going from 145 lbs to 223 lbs. This only increased the depression. I lived every single day miserable and uncomfortable with sleep apnea, chest pains daily (I was convinced I was going to have a heart attack at any moment) and detesting myself. I was depressed to the point where I was suicidal, even making lists of ways I could kill myself. Then January 2019 came and I was determined to turn things around. I changed my diet and was vigilant about working out.

I didn’t want the scale to define my idea of success but after a month and losing only 2 lbs (I wasn’t packing on muscle either) I was completely discouraged. A co-worker told me about Phentermine so I found a Dr and got started on my journey. I lost 20.6 lbs within my first month. My depression subsided, I felt genuinely happy for the first time in 4 years, and it wasn’t just because I was losing weight. I logged everything I ate and stayed within the 1200 calories my Dr recommended. I cut out all alcohol, pasta, rice, potatoes etc and ate really healthy. Early side effects were severely dry throat/nose, occasionally itchy and sleeplessness.

In those early days I took melatonin to ensure I got a good nights sleep. Fast forward 6 months and I have lost 70 lbs, no more depression/sleep apnea/chest pains. I do, however, have severe constipation. I try to eat a lot of fiber rich foods (which don’t seem to really help) and I drink a ton of water. I do have to rely on laxatives, which my body seems to have become a little resistant to. I started taking probiotics and those do seem to offer some relief. I would take constipation any day of the week over how I felt in January of this year. This drug has literally saved my life. It’s not a miracle drug, you have to do the work to be successful. I have no doubt I can maintain this weight loss when I wean off of the prescription because my health matters more to me than making poor food choices. The results I’ve seen with this far outweigh the one side effect I’ve had. I am so incredibly thankful for this!

I began taking Phentermine when I was 28 years old, I needed to lose 20 pounds. The medication gave me instant loads of energy and lifted All my depression. I felt like superwoman of the universe. I was happy and full of life. I excelled at my Nursing job. The weight fell off. I had no appetite. Most of all I could work 10 hrs daily and me and my fiance could dance all night. The only disturbing side effect at the time was very dry mouth. My self confidence soared. Since the medication took my depression away after I lost the 20 lbs I continued to take it. This medication most dangerous side effects are Addiction.

Long story short I became addicted to this Phentermine. I didn't want to live if I couldn't take a lot of it daily. I got down to 89 lbs and the same Dr was still prescribed it. I lost everything in life. I overdosed hundreds of times and nearly died many times. I couldn't hold down a job. Didn't want to live anymore. I was on this horrible drug for 4 years. The Drs will lie to you and tell you it's not addictive. Trust me it is. My advice don't take this drug....

I am a 47 year old female who has been on the weight roller coaster for a while. A friend recommended Phentermine to me. She had great results with it. I spoke to my doctor about it, and after having the blood work and EKG she agreed to prescribe it for 3 months only. My doctor said "This will jump start your metabolism." She told me to lose 10-20 pounds in a 3 month period and then stop taking it.

My results so far are amazing. The day I started Phentermine, I also started the keto diet. I am a pro at keto... no carbs, no sugar etc.. I will be very honest and tell you the 1st day on Phentermine was very abnormal. I took the 37.5 pill very early in the morning. I didn't have time to eat breakfast. I went to work and was very jittery, dry mouth, I had heart palpitations and thought to myself "OMG I don't think I can take this anymore." I forgot to eat lunch, I had absolutely no appetite. I could not sleep on night one. On day 2 it was very different. I only experienced dry mouth. I am eating a lot less. I lost 11 pounds in the 1st 7 days. I believe a lot of that is water weight.

So I am on day 10 today. I love it. My family and co-workers have already noticed a difference in my body and face. I drink a lot of water and I am thinking about joining a gym. I have read all of the mixed reviews. All I can say is it is working for me so far. My doctor refuses to give it to anyone more than 3 months because she claims it can become addictive. So I have a 3 month window to get the weight off. So far so good.

The first time I used Phentermine, I had a great experience! I am 5'2" and weighed about 145 lbs. I lost 20 lbs. after a month of use along with CrossFit exercise. My side effects were: Dry-mouth (which I thought worked out great since I needed to drink plenty of water to get healthy) and the second side effect was an insanely high libido (which initially worked out great for my husband but it got to the point where he couldn't keep up 3x a day at least for a few weeks!). I will say on my workout rest days my heart would race if I took Phentermine without working out. So I would end up jogging or using the elliptical just to sweat it out a bit!

The second time I used Phentermine was 4 years later. Same situation, had 20 pounds I wanted to shed and because my first experience was overall great I didn't think twice about using Phentermine to help reach my goal. The very first morning, pill number 1, I was very excited. Took the pill, drank plenty of water and drove to run some errands before hitting the gym. I began getting very agitated at everything, drivers, people, grocery staff, everything just drove me mad!

I got home to drop off my groceries and I began having suicidal thoughts. Mind you, aside from a little weight gain I dont have any medical issues, I dont take any other medications. I've never had any mental health problems and I've never contemplated suicide in any way shape or form! However, on this day I began to have thoughts about how everyone would be better off without me, how I'm such a failure, etc. (I am happily married with 3 well behaved kids. All honor students never given me any grief to condone me feeling this way.)

I dropped everything and told my daughter what was happening to me. She did her research and threw away the pills and kept filling me up with water in a desperate attempt to flush it out of my system. I spent the next 24 hours wanting to kill myself. Literally, planning how I should die! Wtf?! As soon as it left my system I was back to normal. My period wasnt due for another 10 days so I know I wasnt PMSing and even if I was I've never experienced such a thing. Worst day of my life! Never again! PLEASE BEWARE BEFORE TRYING THIS DRUG!!!

I lost over 40 pounds using Phentermine. This was after 7 years of failing at weight loss... I'm over 40 and pre-menopausal. Weight loss had become really hard. I had put on 50 pounds from the time i was 36 to 42. The biggest side effect I experienced was sleeping less... I would wake up at 4am and really couldn't sleep after that. But it helped my control my appetite enough to redefine my portion sizes and to start controlling my macros. I also started weight training, walking, and running every day. The drug is only one part of the weight loss equation. I've been on it for 4 months now and I feel like the side effects are getting worse (shortness of breath, dry mouth, difficulty sleeping) so I'm taking a break and seeing if I can still lose weight without it.

On half dose for 4 days. Can barely walk. I have been on Phentermine before and the only issues I had were depression, headaches, and insomnia. This time it is extreme back pain, hip pain, legs feel like lead and hurt like hell. Feet burn and tingle, arms hurt, red eyes, insomnia, and suicidal thoughts. Read some other people stayed on it with the leg pain, and then the pain was permanent! I am 54 years old, 213 pounds, active and enjoy walking, gardening, etc. I feel like I am 100 years old on this drug, walk with a shuffle because of the pain, can't hardly get out of a chair. Did I mention brain fog, 1 to 2 hours of sleep?? Horrible drug. I would rather be fat and happy than thin and in constant pain.

Taken it off and on for years. The doctor is only supposed to prescribe it to you for a short time. I unfortunately am addicted to this medication. My body is used to it. I've had good success with weight loss but in trying to come off, my appetite is much WORSE than before and the withdraw is bad as I have tried several times.. To be honest you have to be willing to change your food habits permanently and exercise. It's a good jumpstart which is all it was ever supposed to be. Do not depend on it too much, or it will be pointless and possibly cause more harm than good.

TL;DR- Make sure you have enough time and focus for a healthy balanced lifestyle and diet. Personally I don’t and it affected me horribly. I’ve been having my period every other month for 3-4 weeks at a time. It’s been very heavy and also emotionally draining. I felt incredibly shaky and like my mind was scattered, and it left me severely constipated. I just wish there were more answers about this either from doctors or online but it’s very minimal and not helpful for what happened to me. Hoping that as soon as I stop taking it that everything will go back to normal.

I started taking phentermine right after the start of the new year to kickstart losing weight at a 5’2 20 year old that let myself gain 50+ once I got into a serious relationship. At first every time I stepped on the scale I would be so happy because I’d felt like I had really done it but unfortunately my schedule and habits don’t allow the healthiest or recommended lifestyle. I WANT TO ADD BECAUSE IT IS VERY RELEVANT THAT I AM ON THE NEXPLANON IMPLANT!!!! Two months and I dropped 20 pounds because I was never awake for breakfast or hungry for lunch so I would eat dinner. And then be awake all night because I’d take it at ten in the morning. At work my heart would race and my mind would be all over the place and I figured it would settle as I got used to the medication. Instead I became shaky and confused.

After one month on the medication I began to get my period. I thought it was strange and looked up nexplanon side effects because I’ve had it for two years and haven’t had much of a period yet. It was the week after my phentermine doctors visit that I got it and 3 weeks it went on so I told my phentermine doc about it and he said with the girls who bring it up to him and are also on nexplanon usually say this happens to them as well. It was incredibly heavy so I just figured he’s right and it will go away on its own. Well it did go away but a month later it was back and just as long and as heavy as before. Meanwhile I’m still dizzy and nothing tastes quite right and I’m INCREDIBLY constipated. I personally was afraid of laxatives so that is my next option but I was down to going MAYBE 2x a week if I was lucky and eating enough. More often it would have an abnormal amount of mucus in it and recently just mucus.

Some of these things don’t line up and I started to get scared. I tried bringing it up to someone and they just said I’m pregnant and wouldn’t hear me out. I’m not pregnant and I’m suffering but here I am still taking phentermine because I’m scared of the withdrawal and I fear that I won’t keep up with my weight loss. Yes these things are my fault but I also think that when I bring these concerns to the doctor that they’d recommend taking me off of it. And of course no one should be looking for answers on the internet but that was my last option and even searching this thread I feel like I don’t really know if anyone is experiencing anything similar and unfortunately I only know my sister who is taking the medication as well but everything is smooth sailing for her. It’s just something I feel so alone in and no one seems to have helpful answers.

I have never done well with anti depressants and after these five months and my appointment on Thursday I will be taking myself off of it to see if I can go back to never having a period and going at least once a day. I think it’s more important to have a healthy balanced lifestyle and diet first before allowing yourself this aid. Because without it I think you’ll be miserable.

I was a 90kg woman and I realized I need to change for the better. I have no serious health condition but I was kinda terrified when I step on the scale and it shows the weight that might bring me health troubles in the future. Most of my previous effort on losing weight doesn't work. After losing a few pounds I gained them back more. I stop taking diet pills or slimming products as I learnt that they won't do my liver good. So I went for doctor for consultation and he prescribed that I take Phentermine 30mg slow release.

Since it is an appetite suppressant I hardly feel hungry. 1st week after taking Phentermine, I experienced severe dry mouth and bad breath. There was a day I didn't realized I drank about 4L and I had muscles cramps and felt very tired due to mineral lost. I kept going to the toilet as I pee a lot. The whole week I had trouble sleeping, felt lightheaded and nausea. No appetite but super thirsty. I don't crave for anything but good thing was I still have energy. So I mostly do minor workout. I lost 4kg the 1st week. Probably lose all the water weight. I had other side effects like minor depression, headache and sometimes I felt like vomiting. Almost give up taking it on the 2nd week but glad that I kept it going until 1 month. To be honest, I don't like what I felt when I took the medicine. I felt healthier without it. But it truly shows weight reduction. After the 3rd week, my weight was 84kg. I lose 6kg in just 3 weeks.

After 30 days, I decided not to consume it anymore... I experienced the withdrawal of Phentermine effects about 2 days. I was super tired but that's it. No more lightheaded, dry mouth, nausea, insomnia. I sleep better. So I keep eating low carbs diet, exercise regularly and maintain to drink at least 2.5L a day and I still lose weight. I'm glad I don't have to being dependable on the drug anymore. 4 months without Phentermine my weight now is 72kg. 6kg to go to reach my goal!

What I wanna say here is that Phentermine is good for you to kick start your change of lifestyle if you never been on any strict diet before. It helps to train your body to endure low carb intake while provide you energy. Yes, the side effects are very unpleasant to me. Never in my life I felt such suffering. I regret letting myself gained weight in the 1st place. Never take this medicine for long term as it can be addictive and dangerous. If you experience severe headache please stop taking it and consult to your doctor as this medicine may trigger high blood pressure and other health problems. It's safer if you take it about a month and keep going fit without it then. As side effects may varies according to individual, you can do more research about this medicine. Good luck to you! May you achieved your desired weight and be healthy!

One dose of 15 mg was the most horrible experience! I’ve taken diet pills in the past and none have done what this one did. The first thing that happened was muscle spasms in my neck and upper back followed by what felt like the worst sinus headache ever. It did not suppress my appetite at all but instead made me want to eat everything in sight! Later in the day I began experiencing extreme fatigue and frequent urination. Then diarrhea in the afternoon followed by uncoordinated movements and slurred speech. Irritability and depression and extreme appetite!

Parts of the day felt like “couch lock” that you get when smoking certain strains of **. You know you need to get up to drink, go to bathroom, etc. but can’t move unless you absolutely have to. This is only a good thing when you want to feel this way! I just came if HCG diet and was concerned about overeating. This drug is not the way to go! It could’ve been a bad reaction to absorption rate due to HCG, I don’t know. But no drug is worth this much despair and pain! This was first day first dose of Phentermine. Never again.

I’ve had several people I know take Phentermine with great success, and they all felt great. I discussed it with my doctor and she prescribed it, told me to take 1/2 a pill for the first week, then the full dose after that. Day one, I take the 1/2 pill and followed doctor's orders. I was eating my small frequent meals, drank a lot of water, I was determined to make it work. Within a few hours I noticed a lot of pressure in my eyes, an uncomfortable pressure in my neck, and a headache. I usually get headaches so I wasn’t terribly concerned at first, but as the day went on, it just got worse.

Not long after my husband got home he suggested I go lay down. The headache was so intense I was crying in pain, and vomiting. I should have gone to the ER, but I didn’t have a way there and felt too sick to drive myself. I think my blood pressure was dangerously high, I’m lucky I didn’t have a stroke or heart attack. I stopped after one day; only half a pill. I would have liked for it to work, but at this point I wish I had never taken it.

I started on Phentermine couple months after deciding to make some life changes and to lose weight. I am 5'4", female, and I got careless and comfortable. I lived in my own ignorant bliss of eating whatever I wanted and saw a picture taken of me. I was horrified. I stepped onto the scale, almost 170 lbs. I took tape measurements and began my journey. I ate a balanced diet. Not extreme, not a fad, not a liquid, not anything but balanced. Carbs with protein so the body with synthesize the protein, plenty of water, and made sure to also allow a treat or two every day to keep from going insane on "cheat or treat days."

As I watched 20 lbs drop, I added in the ** at 37.5 mg per day. Huge difference after that. I felt energized, alive, and positive in the process. I believe I have undiagnosed depression. Nothing extreme or dangerous, but it was enough that I felt tired all the time, no energy, and wanted to be locked in a dark room all the time. After starting phentermine, I feel what normal and happy has always looked like to me. I feel energized and full of life. I can get things done... chores around the house, errands, work, etc and it not be a struggle every day.

Now, a couple things here. Phentermine use requires a high water intake. About 7-8 bottled waters a day while on it. The dry mouth effect that many get while on this med is fixed with water. Dry mouth and less saliva production can create a breeding ground for tooth-decaying bacteria and if you are not drinking enough water, your dentist will be the tell all. Your teeth will show the problem, as in cavities and such. Hydrate! Not just for your teeth, but because your body needs it and especially while on this med.

Also be aware that phentermine will more than likely result in a false positive for amphetamines in a urinalysis. Depending on how much you use and how long you use it will determine how it will show on a test. I took a urine screen not 20 minutes ago after taking 37.5 mg of phentermine at about 7:30 am this morning. Faint line indicated that there was a presence of amphetamine in my system, but it was not enough to create a true false positive. I showed the RX bottle to the nurse to prove legal usage of this med and saw my "A" line... very faint, but present. Lack of line indicates a positive. My overall reading was negative. If you choose to use this med, please make your employer/drug tester aware of it, as it can be a career ender if you fail a test over a false positive.

Overall, I like Phentermine a lot. I feel better, inside and out. I am functional again, happy, positive, and productive. Do not overuse it, do not abuse it, do not fail to feed and hydrate your body. This is a medical supplement, not a magic bullet. Balance out your diet, hydrate, get exercise, rest, and this will change your life for the better.

I tried this drug for 4 weeks. I had no side effects whatsoever until the 4th week, my last week. I found I couldn't use the bathroom. It's like my bowels have stopped. My stomach digests the food but its like it just sits in my intestines. That was two months ago and now I take laxatives to go because I'm afraid I won't if I don't. I tried not to take the laxatives, but then it appears the problem hadn't changed. I know the side effects are constipation, but I'm not even constipated. I just feel the urge to go.

Can anyone share some insight please? I'm worried this will last forever and I desperately want to have more children with my husband. But how can I if I live on laxatives? Sure enough these laxatives will hurt me even more so in the long run. I'm praying to god this goes back to normal. I am hating this every day. If anyone here is thinking about trying this, DON'T! Please. I only started this because my mother-in-law has been off and on it for years and I thought it would be great for me too. I only took this product for 4 weeks! I am terrified or what my life will be like if I can't fix this. If I can't have another baby I'm worried my husband will leave me and I love him so much.
