Veterinary Practice News -- A recent groundbreaking study of clinical, histological and immunological data of 22 cases of Pemphigus foliaceus, or PF, shows evidence that it can occur as an adverse drug reaction to the canine flea and tick preventive ProMeris.
PF is the most common spontaneously occurring autoimmune skin disease of dogs and typically displays as lesions on the face, nasal planum and ears. The reaction is rare but serious, says the study’s lead author, Thierry Olivry, DrVet, PhD, Dipl. ACVD, of North Carolina State University.
