Frontline Reviews

Absolutely ineffective, Don't waste your money. This product does nothing. I am 53 and never have I ever had an issue like this. This flea medicine and many others no longer work. Buyer beware. Buyer beware.

I found two kitten and they were full of flea so we bath them in Dawn dish soap, brush them with a flea comb and waited until the next day Like the direction state before Appling Frontline for small cat 1.5 pds. Within 3 days after they both were loaded with fleas, it was like we didn't use anything. I been combining them 3 times a day now, spraying my home daily. I'm afraid to use anything on them beside dawn dish soap until the frontline has wore off. I will be using the Seresto collar instead. I have 2 other cats that have these collar on and with the Kittens having bad flea problems, I didn't find one flea on my other 2 cats. If I would of knew I can use seresto collars on kitten I would of bought these instead of frontline. I'm highly disappointed in Frontline

I bought this product for my cat. In one month my cat passed away. She was 13 months old and healthy. I would advise to my worst enemy NOT TO BUY this product! 12 years ago I used Frontline for my dog. He died from sarcoma of the skin. People need to be aware about Frontline Plus. DO NOT BUY THIS PRODUCT.

I bought Frontline Plus for my dogs and cat. Used the first month absolutely no results expect the flea have tripled. My dogs' second month absolutely no results either. Ten years ago I used this and it was great. Now my dogs are miserable. I lost way more money than that company should be allowed to charge for sewer water. Absolute trash.

I've been using this product for years but this last year it has not worked at all. Within less than 2 weeks my pom chi is covered in fleas. Now after reading reviews I'm shocked to have read that pets have died! OMG!! Are you serious!! You are selling an expensive product that is killing animals and doesn't work! What is wrong with you! Never again! How could you?

Treated two cats and both lost hair. Attempted to contact and got nowhere. Used it for years and it was our go to and kept my house of 6 cats free of fleas and ticks. Now it causes bald spots, fleas don't even reduce in number and ticks are also oblivious and unaffected. It doesn't work and hurts animals.

This product used to work, it no longer does and they it is still the most highly regarded, costly topical treatment on the market. When I tried to report this to the company, it disconnects. Scam product now.

I rescue animals of all kinds. I put Frontline Plus on my five small dogs and the fleas are still all over them. This was wasted money that I can’t afford on a limited income. This product is expensive and for it not to work is a waste! I am on disability, since I can’t work a normal job I started an animal rescue. It gives me purpose. I will no longer recommend your products to those ask my advice. The cost is outrageous for a product that doesn’t work!

I applied this to my dogs for many years, and so did the shelter where they lived. They eventually got cancer and I'm uncertain if it's related to Frontline. They lived a very active life even to the end and had the highest quality dog food. One of the dog's cancer became prone to seizures. I noticed after time that he'd have a seizure within a day of applying Frontline. I stopped giving it to him and he never had another seizure.

My cat has got sores on her tummy after administering this killer product. She stopped eating, and was not herself after applying this product. She his now on antibiotics and ** for her sores. I BEG YOU PLEASE DO NOT USE THIS PRODUCT ON YOUR CAT. It will do more harm than good. It might kill fleas, plus kill your cat as well.

In May of 2019, I used Frontline on my beloved 13-year-old cat NeiNei. Within hours she could no longer stand up fully or walk straight. She fell over constantly, lost her appetite, and the once happiest little girl in the world was looking lost and upset. I called the vet immediately, and we agreed to monitor her. The vet was unaware of Frontline causing neurological issues and attributed the situation more to her age (13). I know she was happy and playful before I applied the Frontline, and yet only hours after she was on her way out. I never believed it was a coincidence, and I still blame myself for applying the flea treatment.

Please do NOT use this product on small animals. My enigmatic, fun loving, energetic Yorkshire Terrier Aged 10, who won prizes for his wagging tail has died after using Frontline flea product (measured for weight) with Toxic Lymphoma. First dose ever end August 2020 caused lymph nodes to swell to 4cm diameter and organ failure, died 4.44am 1st November 2020. RIP. Tragically Unfair. Please note 1 star is minimum, I wish to portray none. Please adjust Consumer Affairs.

After using Frontline Plus for cats during the last week of August 2019 our beloved cat Annie died on September 1, 2019. He organs literally shut down and there was no reviving her. This product is toxic and lethal! If you are wondering why I waited to write a review the simple fact is I was too upset and I blamed myself for using it. Until recently I could not even look at her photos without crying. Our Maine Coon Andy, Annie's brother survived although he had minor side effects. He too grieved for months after her passing. Frontline Plus should not even be sold! It is toxic! It is lethal! Frontline Plus will kill your cats!

Do not give your pets for a night. I I had a nine-year-old Shih Tzu and this product killed him. He started having seizures and tremors in the barely walk and then stop eating and then stop drinking and died. I gave him his medication August 18. He started acting funny around the 20th. Seizures that the vet was no help. He died today September 5 at four in the morning. This company needs to be exposed. Do not give your dogs this stuff. Do not give your kids the stuff. It is poison. They killed my dog. This is crazy. My dog was perfectly healthy before I gave him this and regardless of what warnings on the box if you know and all these people are complaining you have lost pets why are they still in business?

The vet prescribed this because they would not sell me bravado until I made a well check appointment, I understand that but now my cat has lost 6 pounds and isn't doing great. So another appt to come for her. I am absolutely angry about it and am feeling guilty because I put it on her and now watch her diminish slowly in front of me. I'm hoping she will bounce back. She is an outside cat and energetic usually now she is in the house most of the time sleeping. I don't want to lose my cat. I'm not ready for that. She was my mom's the first 5 yrs of her life before my mom passed away. So NEVER AGAIN will I use this. She is still young to me and has many more years to come. I hope we can turn this around for her.

This is 3 days after the second application, the first application was 30 days ago and this morning I removed 6 more ticks. I removed 12 yesterday. I did not know or suspect any insect infestation on the dog until I cut her hair. The complaint desk tried to up-sale me onto Nexgard which requires a veterinarian prescription. They will refund purchase price if I have proof of purchase. I will replace the bed and use a valid tick insecticide on the downstairs.

I had 2 dogs. I just lost one of them who to chronic seizures this year as of April that led to paralysis and brain damage even though he was on seizure meds prescribed by a vet. My other dog also had 1 seizure a day after an application. Both dogs had been on the meds for a few years. Their seizures tended to happen just a day or two after Frontline Plus application. My vet took my existing dog off Frontline and Heartgard immediately. I believe some dogs' systems do not dissipate these chemicals over the course of a month resulting in a toxic buildup. These meds are - you guessed it - neurotoxins. Am heartbroken over my recent loss of the sweetest rescue I've ever had. Will never use these products again.

I’ve had cats for 55 years. I currently have a 10yr cat and a very young pregnant cat. (Lockdown delayed vet appointment then she flew out the door and returned pregnant.) We’re otherwise responsible pet owners! Years ago my vet used Frontline on my 3yr Italian Greyhound who from the next day forward had grand mal seizures 6-7 times a month but the vet of 50+ yrs said he’d never heard of that happening. I always felt then but I’m even more certain now after giving Frontline to our 2 cats 2 weeks ago - this product is dangerous to many animals and should have been taken off the market long ago!

I asked my roommate to pick up some Frontline after he let the cats out and they came back with fleas. He drops the packages on my desk and helps me apply the treatments to four cats. Within ten minutes, one of my creatures isn't acting right. Ten minutes later, she's agitated and panting. She's already lost interest in playing, is running around, and panting furiously. Oh no...

Applicator difficult. I currently have 4 cats, and have had cats for about 40 years. I have always used Frontline. However, I will no longer use it, due to the package being so difficult to open. When they began using the new packaging, I was not satisfied and continue to not be! It is too difficult to open. I will no longer use it!!

Sunday March 8th 2020 I administered Feline Frontline to my Cat who was 15 pounds and 10 years old. Monday March 9th 2020 I came home from work and found him lying in my bedroom floor having seizures. My husband and I wrapped him in a towel and started our way to the emergency vet. Before we made it to the end of our road we live on my beloved passed away. We adopted him when he was two years old. He was only an indoor cat and had just had a healthy checkup at the vet. I cannot honestly say that Front-Line caused his death but it is ironic. Kitty Heaven is he.

Carey - 8 years old - mixed breed - 35 lbs. We applied Frontline Gold for the first time ever to our dog on 01/16/20. Within 5 hours she would randomly scream out in pain/because she was scared and jump into our arms. At the time we thought maybe she hurt her leg or back and would touch her spine, rotate her legs, etc. without finding any indication of soreness anywhere on her body. This would happen sporadically on Friday and Saturday. By Saturday evening, it was happening more frequently. And at this point we realized that our dog was having mild seizures. She was not losing consciousness, but she would cry out/get this look about her and then burrow into us and her whole little body would tense up, she would lick her lips (salivating), and stretch out her neck and put her head high into the air.

Frontline Gold was purchased & administered to my cat 12/11 @ vet clinic. Brought in healthy, came home & sneezed for several days, scratched & licked obsessively causing loss of hair, peeling pads and lumps appearing on various parts of body. Cat has lost appetite for food & water and has lost weight. She is in pain, disassociating any human contact, constantly sleeping in secluded, dark places in home. Fearing her death, took back to vet for help. Paid $330 for bloodwork (CBC) to check for liver &/or kidney maladies; ruled out all fatal cat diseases; rec’d skin scrape 2, ** 80 mg/ml injection; provided ** .3 for pain maintenance.

My cat is an older indoor feline and only goes out occasionally on the front porch. I have been treating him with Frontline Gold and called the vet because it does not seem to be working. He said I can give to him 2 times a month instead of once and that seems to be working a bit better. I do think the fleas build a resistance to these meds, only wish they were a bit cheaper since they seem to take so long to start working.

Their money back guarantee is a joke!!! I purchased a 6 dose Frontline Plus for my dogs. After 10 days there was no change or relief. Treated them with another dose. It got worse. I went back and purchased ** and saw a noticeable change within 48 hours. I called to express my concerns. I was told in order for the money back guarantee I had to treat for 3 months. My dog was bleeding in spots from the chewing/scratching. I was NOT subjecting her to that for 3 months when it was clear that after one month your treatment was not working. I was just told by one of your representatives (reading from a script) that how your product works is that it kills adult fleas and keeps females from laying more eggs.

I have treated my 4 cats over 4 months & continue to find fleas. We have followed protocols for flea treatment of our home as recommended by our vet. Seresto collars seem better, but they cause scratching & hair loss at neck. I will admit the collars seem to be more effective, but our vet now is recommending **. I think the fleas are just becoming resistant. These are indoor cats, no less. We are very frustrated & concerned for our fur babies' welfare.

Started using Frontline Plus 2 years ago. At one stage I was using it every two weeks. It just doesn't work, my 3 cats are infested and so is my house. When I complained to the the company they sent me a questionnaire to fill out - I filled it out and they replied rather flippantly- saying they are picking them up from outside. Before that I was using Advantage but was buying it from the chemist but at £27 for 3 pipettes it was too expensive - but it worked. My cats are 15, 15 and 16 years old and I don't really want to keep stressing them out with fortnightly defleaing, hoovering several times a day and bathing in cat shampoo which they all hate) so I'm now trying Advantage again and getting it a lot cheaper online - hope this works.

I contacted them to tell them I’ve got fleas for months now and been using product for years. They only try to tell me how to bomb and clean my house. I told them I’m diligent with my Dyson vac and clean every day! They told me to keep using the frontline. It will work. After two ear hematomas and an abscess to my little dog leg I found out he’s suffering from a flea allergy and of course it’s costed me!! Finally the doctor's office told me that Frontline Plus hasn’t worked for a couple years now and they prescribed NexGard which I found is from this same lying company. But I used it because I was desperate and within a week he’s better and stopped shaking his head and scratching. Still to doctor's office told me to use nexgard only as needed (Not monthly) because it isn’t good for your pet.

I purchased Frontline for my cat, from a Walmart store in Hamilton, NJ. My cat was a very loving cat, very playful, wake me up every morning, and just a part of my family. I applied Frontline on my cat on Thursday night, 10/3/19. On early Monday morning 10/7/19, all of a sudden, my cat's body began to start jumping, flipping, and he started to shake and seizure. His chest began to jump, and his heart began to race extremely fast, and then he died on us. After being in complete shock, an emotional wreck, and angry, I decided to contact Frontline and let them know what their product killed my cat. The person that I spoke to, asked me a few questions, gave me a reference number, and told me that someone will contact me asap.
