Adverse Certifect Reaction

The application appeared to have caused a 48 hour period of lethargy that was unusual enough for a mention to my Vet. The application was applied during the first week of July. About three weeks later we found a series of crusty lesions on her back and right side that I suspected as being scabies or mange and did not associate them with the medication. Emergency trip to the Vet. After being shaved around the affected area it became apparent that the medication had severely irritated her skin at the point of application, an area where the medication had "pooled", and an area down her right side where the medication had run down. She had no intestinal reaction that was noticed.

This medication appears to be unpredictable and seemingly dangerous. Are there any serious inquiries going out to Merial?

I will not use any of this stuff again.

Not that I know of. I brought mine back to the vet, they refunded it, and called the rep with the lot # and information. He told the vet that they/he hasn't heard anything about adverse reactions. Load of bs if you ask me as you can find it all over the internet just by googling.

Certifect Reactions

My Vet took pictures and has been in contact with the rep. No word yet - Yes, the net is a wealth of information on adverse reactions. Scary stuff!

That is terrible. Hope all the dogs are going to be OK. Frontline works for me-so I will stick w/that. Thanks so much for the heads-up.

I have had real good luck with Trifexis(sp).

Flea/worm/Heartworm prevention in a monthly pill. A little spendy, but has worked wonders on the fleas!

I would strongly suggest Revolution. Even takes care of mange and heartworms. I used it on a german shepherd/husky mix and had no issues what so ever.

I don't like revolution for dogs... I have seen too many dogs that were on it but got heartworms anyway. Maybe the dogs rolled and got too much off so they didn't absorb enough to be protected or the owners did it wrong or something, but not worth the risk to me given how prevalent heartworms are where I live. It also does't do anything for intestinal parasites in dogs (does in cats though) so you wind up having to dose them regularly (like the horses) with another product for hook and roundworms every few months anyway.

We used Certifect on our 2 dogs just over a week ago. One dog...a 40kg Weimeraner was absolutely fine however our other dog, collie cross husky
Around 28kg became very lethargic and "floppy". If he doesnt want to play then something is definitely wrong. We rang our vet late at night and he recommended we bath the dog with a washing up liquid to break down the oil/grease content in the product and remove the Certifect. He rang back an hour or so later to confirm the dog was okay....he was much better by now. He also said at the time that he had an antidote ???? For the product! We will NEVER use this product again and will return to our usual flea and tick control....we live in Cyprus...the manufacturers have written to us saying they have not heard of this problem before in Cyprus! However.....looking on other websites (including Amazon) this product does not have very good reviews.

Used it on all three of our dogs and didn't have any adverse reactions.

Dpickering.......I have been in touch with Merial about the problems with my dog! However, their reply was that this product has had no adverse reactions (in Free Cyprus...and no deaths have been reported either, free Cyprus meaning Southern Cyprus)) however, they did not say about UK or anywhere else. I looked at many comments about Certifect on UK sites and many of them did not recommend the product at all. Whether it does affect certain breeds more than others is not/has not been proved. However, my dog which was affected quite badly is a collie cross husky and on speaking to our vet it would appear that a dog which was also affected in our village was a husky too. As I say....Im will not use the product again, it isnt worth the risk!
I would also add that my normal tick/ flea medication is Frontline. The only reason I used Certifect was beacuse the vet simply did not have any available and said he didnt know if he would again!
