[Suspected adverse drug reactions in 2004]

We received 62 reports of suspected adverse events (SARs) for the year 2004. Their number and repartition according to affected animals and active substances were comparable with the previous year. The distributors or manufacturers submitted most of the declarations, but the proportion submitted by practicing veterinarians is slowly growing. 72% of the declarations dealt with adverse reactions in small animals (cats and dogs), followed by cattle and horses. Antiparasitics, anti-inflammatory drugs and immunologicals were the most frequently mentioned therapeutic classes, which are listed here according to the international ATCvet classification. A report from abroad about a fatality following injection of an antibiotic preparation for cattle prompted Swissmedic to review the security of this medication also sold on the Swiss market. It was decided to modify the package insert to warn about the danger of inadvertent self-injection in humans, to reduce the risk of similar accidents in Switzerland. We hope that the pharmacovigilance system will enjoy an increasing awareness by the practicing veterinarians.
