Adverse Drug Reactions: Report of the Australian Veterinary Association Adverse Drug Reaction Subcommittee, 1993

SUMMARY Fifty‐nine reports of suspected adverse drug reactions (ADRs) were received by the Adverse Drug Reaction Subcommittee of the Australian Veterinary Association from April 1992–March 1993 inclusive.The number of reports received/number of animals involved per species was: dogs (30/43); cats (11/14); horses (8/10); cattle (9/30); ferret (1/1). Of these, 37 (63%) were classified as definite ADRs and 12 (20%) as probable ADRs. In 10 (17%) reports an ADR could not be substantiated or there was insufficient information available to make a decision.Twenty‐three reports involved apparent hypersensitivity reactions and 5 reports were associated with ‘off‐label’ use. Of the definite and probable reports of suspect ADRs the most frequent types of drugs involved were antimicrobials (9 reports), anthelmintics (9 reports), vaccines (7 reports), insecticides (6 reports), vitamin preparations (6 reports), topical anti‐inflammatory/antimicrobial/antifungal skin preparations (3 reports) and nonsteroidal anti‐inflammatory preparations (3 reports). Single reports concerning definite or probable ADRs to an anticholinergic, an anaesthetic agent, a corticosteroid, an anabolic steroid and a chondroprotective drug were received.
