Comments on Bravecto: Prevention or Killer? How does bravecto work?

Both my cats had an immediate reaction after having the 12 week coverage Bravecto spot on flea treatment. My younger cat (7) started foaming at the mouth and throwing up. My older cat (14) had projectile vomiting. The vet was the one that administered it and he told us it shouldn't matter if they get it into their mouth as it gets into their bloodstream anyway (idiot!). Meanwhile my older cat continued to be sick, started drinking large amounts of water to the point I had to keep refilling two bowls twice daily. She started losing weight and became very unsteady on her feet. This past weekend she suddenly crashed - stopped eating and drinking. So we took her back to the vets where she was weighed and given a rectal thermometer. She had lost half a kilo in a month after the Bravecto. She was running a temp of a 104 degrees. We had to keep her in overnight on IV drips and antiobiotics whilst waiting for her bloodwork to come back. Her bloodwork came back showing she has pancreatitis and now diabetes. I'm sure the pancreatitis was brought on by the flea treatment and the diabetes is brought on by the pancreatitis, it's never the other way around. She has to remain on the IV drip for now until she's well enough to be released and has to have insulin treatments twice daily. All because we trusted this product recommended by our vet!

I switched my dogs to Bravecto from frontline when my son was born. 1.5 years later the first died from spleen cancer. A year later my second one has been diagnosed the same. They were 9 & 11 when diagnosed. Fed a healthy diet, few if any table scraps, and a healthy weight, annual physicals. I understand it isn't an uncommon cancer for larger breeds, but for two dogs, both mutts three years apart in age, and within 2.5 years of receiving Bravecto to be diagnosed the same? Do your research.

I gave my 30lb dog bravecto yesterday for the first time after finding a tick and thousands of eggs in our bed. I wish I had read up on it first, but I was just frantically trying to rid us of ticks. Today she is lethargic, and I had to make her get out of bed to go outside this morning. Is there anything I can be giving her to negate the effects of the poison (bravecto) I gave her? Please help! I don't want to see long term issues because of this either!

Vet keeps insisting my dog is not sick because of Bravecto even though all her serious problems started the week after we gave it to her. She is 13 or 14 years old and had arthritis and a slight infection, which she got antibiotics for before we gave her the bravecto (I waited until all treatment was done even though I was told I did not need to wait).
She stopped eating and could barely be enticed to eat at all, even her favorite foods. She drank constantly, was very lethargic and lost 7 of her 25 pounds in a month! She was overweight but now is very skinny and she can barely get up and walk and looks awful. Eyes look awful too. Tests today showed she has pancreatitis and her lymph nodes are swollen -- so Vet recommended hospital stay to get fluids and medication for pancreatitis and then once we get it under control to go to an oncologist for the lymph nodes.
I could not bear to leave her there in a cage alone at night, she seems close to death. They gave her fluids and shots of medicine and sent meds home with me with instructions for the next few days but we had to carry her into the house, she is not even wagging her tail.
I do not believe in coincidences -- she had minor health issues before the bravecto and within a week of taking it has deteriorated so dramatically. Every time I brought up bravecto he deflected and said it didn't cause pancreas or liver problems or lymphoma.

Gave my sweet girl (4 Yrs.) Bravecto two weeks ago. She has been vomiting and has diarrhea. Right after I gave her the first dose, she started to shake and drool. This has stopped for the time being. What really concerns me now is she is not eating (it's been a day) and this is very unusual for her. She's just laying down all the time now. I read about the side effects and that some dogs have died and I was filled with terror. I too her to the vet. I saw a vet tech, she explained to me that Bravecto was not a poison, just an antiparisitic. Said she gives it to her own dog and it was just fine. She sad it has been approved by the FDA and they don't base their opinions on anything that would be posted on Google or facebook. I demanded my money back and said I would be looking for a hollistic vet. They did not care that they were losing a client..that was obvious. I'm still so scared my stomach is turning. If I lose her, I will sue Merck on a class action suit. I think the Big Pharma companies and the vets involved just want to pad their wallets and don't give a rats ass about our beloved pets!

I live in Florida, in an area that's known for its heavy duty flea infestation. I got a taste of this when I first moved here with my sweet cat. It was a horror for her, she was ravaged. I tried EVERY single "natural" treatment, including the ones you mention above. None took care of the fleas. It was either let her suffer or try a vet's spot on suggestion. I used Multi Advantage, and have been for 2 years now. It did the job. I HATE giving it to her, HATE IT, but unfortunately I don't have a choice. Just here in the building I live in, folks' animals are flea infested, they carry them everywhere (we used to have to document treatment but no more and too many people don't take care of their animals). I feed her the most healthy foods, so she's a strong girl, but I couldn't just let her go on suffering with the fleas. I watch her closely for ANY side effects (I know there must be some, as the crap is poison) but haven't noticed any changes with her. I went to the vet 2 weeks ago, for something unrelated to fleas, thought I'd pick up some Advantage since the time was close, and vet suggested Bravecto. The FIRST thing I asked, since it's said to last so long, is about its SAFETY. I asked her directly, and she answered that ohhh she's been using it for nearly a year and has had NO reports of side effects. I believed her, stupidly enough. I gave my cat the Bravecto. I have not noticed side effects (thank God), but I have noticed she's exhibiting behavior manifested when she was flea infested - smelling the carpet, limiting her movement, etc. So not only have I maybe hurt her, the poison might not even work for flea prevention/treatment (the vet did find a flea on her).
Sorry to go on for so long, but I just wanted to speak for those of us who live in sub tropical/tropical environments and might not have the luxury of "natural" things working.
I also wanted to ask what I should do. Is there anything I can give her to avoid becoming ill from this stuff? If it hasn't worked and she gets fleas all over her, what the heck do I do then??
I'm so sad for the folks who lost their animals, and for the sweet pets and people struggling now with the awful side effects. I'm certainly not surprised. Killer meds are given to humans, and animals, well, they're considered PROPERTY, so why not use them as experiments for the latest pharma nightmare drugs they hope will pan out and sell?
I surely will never go to that vet again, for clearly misleading me, and/or simply being willfully ignorant and not doing the research she should be doing.
I blame myself, too. I thought it would be easier on her if I gave her something that would last longer so I wouldn't have to bother her monthly, but I should NOT have started her on something new without my OWN research. I feel terrible about it, just like when she had such an awful flea infestation and I wasn't even aware of it for a while. I was new to the area, had no idea it could get so bad, and she's an indoor cat.
I feel her grain-free dry and not the healthiest but pretty good wet food. It's the only one she'll eat. I also give her a yeast/garlic powder in her food sometimes, but I'm not so sure yeast is okay for cats?, so I don't do it all the time, just once a week or so.
Thanks for your time, and thanks Dr. Falconer for providing this forum.

My dog (a GSD) has been taking Braveto for 2 years. I have not noticed any side effects. We are in a heavily wooded area and have removed ticks weekly from a previous dog (a lab), and didn't want to go through that again, because we suspect her illness was due to so many tick infestations. Your article is informative and has given us something to think about. We have found several dead ticks on her, and have been pleased to see proof that the product works, but no one wants a remedy to be toxic to their animals. May have to adjust our decision after your article.

Please don't use Bravecto!
Teddy now suffers with these episodes on a regular basis since October when we started bravecto. Before this he was never ill!
He has been to the vets multiple times since October and even to a specialist vet where he had blood tests, ultrasound and ECG where they couldn't find anything wrong.
He has had extremely low white blood cells and then extremely high red blood cells.
He will now be having a CT scan and endoscopy. This has cost thousands for something my vet recommended I give to my dog! ????

Please tell me good or bad about Seresto flea and tick collar. Also if my dog is just starting Apoquel and using Seresto collar and has in last couple years been on Sentinel Heartworm meds (I ran out in Nov and haven't refilled yet) but I'm afraid to put him on and afraid not to. He has enviroñmental allergies and started on these new meds and I don't know enough about Sentinel or Seresto as to how safe this is going to be for. Vet recommends all three and says she gives Apoquel to her dogs. Any information would be appreciated. Thank you.

Unfortunately, the lies the drug companies tell are simply "advertising". Humans seem to see rampant lie telling as an acceptable way of life. Why else would our politicians get away with everything they do? They get away with it because They R Us. No one cares that today everything is a lie; no one champions honesty and truth; only GREED matters.

This is such an important issue, the terrible side effects of toxins comprising man-made drugs. Cedar oil repels fleas and ticks much better and does no harm. Diatomaceous earth kills fleas externally and parasites internally, with no side effects. A small amount of garlic added to dog and cat meals also stops fleas from biting, and plain old vinegar is the best stuff yet. There is no need to fill the pockets of the evil drug companies who market their toxic crap as "safe" when clearly it's not. Thank you Dr. Falconer for getting the word out about these dangerous products, and I am so sorry for those of you who found out too late, whose pets have already been damaged or killed. The pharmaceutical companies should have their immunity revoked and we should sue them into oblivion.

My vet wanted to give my German Shepherd an injection for fleas and ticks, we do live in an area where ticks are a problem. When he told me it would kill them when they bit her, I couldn't see the benefit, mentioned that she would have this poison in her system --- he became somewhat cold and distant. He had always been friendly and open with me. Same visit, I mentioned her itching and development of hives when she was last innoculated. He didn't even check her skin or red irritated ears, just suggested fish oil added to her diet and using aloe for her hives.
I have since ceased her monthly heartworm and have no intention of further inoculations. I may need to find new vet.

We started giving our two labs Nexguard early last year. The 12 year old has never shown any signs of side effects but my five year old boy had very slight seizures where he would walk really strangely for a couple of minutes, lie down then get up a few minutes later as though nothing had happened. I was putting it down to perhaps having just been bitten by an ant in the grass - til it happened and he hadn't been outside for ages. He had his worse seizure on 2nd November which I recorded on my camera to show our vet which lasted 2.29 mins. He had another one the next day but not quite so severe. On 4th November I saw the FB page 'Does Bravecto Kill Dogs' and it made me wonder about Nexguard and I found a similar FB page. I rang my husband and asked him what date he had last given the pups their treatment - 1st November..... We took Clyde to the vet where he had blood samples taken and checked for various ailments - all came back clear. Our vet said he had never heard of any problems with Nexguard and in fact he encouraged my husband to try it out on Clyde again when I was overseas for 3 weeks!!! Needless to say my husband didn't do so. We live in Queensland Australia where there is a problem with paralysis ticks so I am now paranoid and don't know what to do for best....

My dog started having seziures after the 2nd dose of bravecto within a month.She would just collapse in the yard and have this episode for like 30-40 sec.I would manage afterwards to put her on her feet and gently bringing her inside the house where she would just breathe heavily and eventually fall asleep.
I was so scared, the vet said it couldn`t be from Bravecto, yet it was the only thing it changed.I also asked him how come is so safe Bravecto for her given the fact that she already had for over a year hepatic problems and getting treatment for hepatic disease.The answer was that it was well tolerated and noone ever complained and he also gave it to his own dogs and nothing happend.
Well I found the group online about it and it all clicked for me .It made perfect sense.I even called Merck and I reported the side effect.The woman on the line told me they never heard of seizures before, noone reported it before and is a safe medicine.However she noted my adverse effects and promsied to call me back with a case number.Well ,I called them back 3 times asking for a case number and they said they don t have one yet, they can t give me oneyet, soon, soon.It`s been almost 5 months and I still don`t have a case number.I guess that `s the whole point
However, I refused to feed my dog her usual kibble for heaptic diusease and I started to feed her a home made diet for hepatic disease.It`s been 5 months she is on this food and almost 3 months since she didn t have seizures anymore.
I will never ever give Bravecto to any of my dogs ever again.I have 2 other dogs and they were fine, only the 3rd one had the seizures.It is not worth taking the risk and giving this pesticide to your dogs.I experienced this first-hand.It`s heartbreaking to see your beloved pet struggling and not beiong able to do anything wondering if you get to spend another day with them or what is going to happen next.I blamed myself so much for giving Bravecto to my dogs.After I gave it to them the first time , I read some reviews on the internet from people and weren t good and I was scared, but then I asked the vet and he said is perfectly safe.So I trusted him, and my beloved girl got seizures.
It really infuriated me so much everything that happend and after I saw what other poeople went through with their pets it blows my mind that this pesticide is still out there on the market.Noone investigates it because they are big Pharma and they don t give a s*** about people s reports and don t give them case numbers because is not in their interest to report it to FDA or EMA.

Comfortis killed my Boxer just a few months ago. I knew this was a pesticide, and like many others, was told by our Vet that it's safe. This new drug is no different. I shouldn't be surprised that these doctors are passing these poisons off to humans and their pets. I was told that the stuff was safe and plant drives and is used on our fruits and vegetables. This stuff kills the guts of our pets. Mine never recovered.

I gave my 10 yr old perfectly healthy dog Nexgard for the first time on Nov 7th of 2016. On Nov 22 she started with loose stools and on Nov 23 I noticed her lymph nodes were enlarged. On Nov 25th she was diagnosed with Lymphoma. She is still with me right now but I am not sure for how long, I know it won't be too much longer. I know deep down had I not given her that pill we wouldn't be battling Lymphoma right now.

On November 14 2016 I took my sweet, lively, healthy Shiba Inu to the vet for her yearly exam. Lucy has never had a flea or tick so never worried to treat her as we haven't expiernced any problems. On this visit the vet highly recommended a treatment called " Bravecto". Little did I know at that time about this drug because I never treated my baby for fleas. Got home and feed Lucy and gave her the Bravecto- she spit it out- I picked it up and wrapped it in cheese and she ate it! Within 2 hours she was in a very deep sleep in the couch and I couldn't wake her to go to bed that night. The next morning our nightmare began! Vomiting, seemed confused and dazed " out of touch" loose stools while throwing up. Excess thirst. I went on google to research "Bravecto" and was horrified with my findings. I found the FB group called " Does Bravecto Kill Dogs". Thank GOd I did!! Now I was even more nervous but had info to share with my vet. Trip to the vet that morning and informed vet and even he was surprised at the turn in her health over night. At that time he informed me that he had a case before after the pet took Bravecto and informed me he would
Call Mersk which he did while I was there. I showed him info I pulled up on The FB group and he informed me that it has been approved by FDA and he then showed me that he had prescribed over 600 dosages and I was only the second to complain of complications. The next 4 days there was daily visits to the vet for hours at a time for IV for fluids and antibiotics at the same time blood work was drawn., I refused to let her stay overnight as there was no one overseeing her treatment during the night. I wanted her home with me to monitor... after the 5th day she was coming around but still not eating. She lost a lot of weight over 5 days. But she was coming around. I went back to the FB group and found info about dextoing and had seen several mention "Denamarin" for detoxin, I rang my Vet and asked for it and went to the office and started Lucy on it right away. We are going on 2 1/2 months and she has been on the Denamarin and continues to show improvement. Will visit the vet again on Feb 9th for follow up and more blood work. I don't know what lays ahead for long term damage but I know for a fact this pesticide not only was the cause for my precious girl to suffer and still suffer but cost me so much more money than the actual dosage of Bravecto! Never will I ever give this to my baby and I have become the voice for my girl and I spread info that is posted on the FB page daily about this horrible treatment in hopes to reach someone before it is so late. I willl never forgive myself for not researching this before I forced it to be eaten by my girl burried in cheese!
Thank you for your post to help educate everyone of the dangers of this pesticide and I apologize for the length of this email.

Great article. Please just edit Merial don't make Bravecto Merck do. Merial make Nexgard another in same class. The latest addition is Simparica made by Zoetis. All three are in same class of new Isoxylines.
