The toxicity and adverse effects of selected drugs in animals--overview.

Therapeutic products quite often are causes of poisoning in both small and large animals. Drug poisonings in animals occur commonly due to off-label use of medicines, wrong dosage, negligence, accidental ingestion and deliberate poisonings. Toxicity of veterinary drugs may become evident also in therapeutic doses when adverse effects may occur. The aim of this review is to inform veterinary specialists about both veterinary and human drugs, specifically antiparasitics, non-steroidal anti-inflammatory drugs and other medicinal substances, which are most often reported to cause acute poisonings or adverse reactions in animals and to contribute to. their broader knowledge and more accurate use of medicines, improving instructions to the animal owners and, hopefully, decrease the incidence of drug poisonings in animals.
