A North Carolina State University study has linked ProMeris Flea Treatment to Pemphigus foliaceus (PF), showing “evidence that it can occur as an adverse drug reaction”. Pfizer Animal Health who markets this product is discontinuing ProMeris.
Veterinary Practice News states “Since ProMeris’ introduction to U.S. and European markets in 2007, veterinarians have reported this adverse reaction, but previous case studies failed to use a drug-reaction probability scale and therefore an ADR couldn’t be definitively identified.” However Dr. Olivry of North Carolina State University “says this examination of all parameters studied suggests that this ADR might represent the first instance of contact drug-triggered PF to be published in Veterinary Dermatology.”
“The study found that ProMeris Duo-associated PF not only had a reaction to the same drug, but also shared many of the same phenotypes. Lesions in PD-triggered PF were found to be both localized and at distant locations from the point of application.”
If you are using ProMeris flea treatment on your dog, please consult with your veterinarian and provide him/her to this article: http://www.veterinarypracticenews.com/vet-breaking-news/2011/04/18/study-links-promeris-to-pemphigus-foliaceus-pfizer-stopping-its-production.aspx.
