[Reported adverse reactions due to veterinary drugs in 2006]

We received 190 reports of suspected adverse events (SARs) following the use of veterinary drugs for the year 2006: 118 declarations for veterinary drugs and 72 declarations following the application of immunolgical medicinal products. Most of the 118 declarations relate to the use of antiparasitic drugs (48%) and every second declaration to drug use in dogs. Other drug classes concerned were, in decreasing order, antiinfectives (20%) and drugs used off-label (12%; other target species or other indication). For the vaccines, most of the reactions occurred in dogs (62%) followed by horses (11%) and cattle (10%). The most frequently reported reactions concerned the use of a vaccine against piroplasmosis. Another 349 requests for information were processed by the Swiss Toxicological Information center. We also present a case of a serious adverse reaction in form of a Stevens-Johnson syndrome in a cat as well as a case of ketamine abuse. We note the growing interest of practicing veterinarians with pleasure and are currently working on further adaptations to the system.
