Abstract An adverse drug reaction (ADR) is a serious concern for practicing veterinarians and other health professionals, and refers to an unintended, undesired and unexpected response to a drug that negatively affects the patient's health. It may be iatrogenic or genetically induced, and may result in death of the affected animal. The ADRs are often complicated and unexpected due to myriad clinical symptoms and multiple mechanisms of drug-host interaction. Toxicity due to commonly used drugs is not uncommon when they are used injudiciously or for a prolonged period. Licosamides, exclusively prescribed against anaerobic pyoderma, often ends with diarrhoea and vomiting in canines. Treatment with Penicillin andβ -lactam antibiotics induces onset of pemphigious vulgare, drug allergy or hypersensitivity. Chloroamphenicol and aminoglycosides causes Gray's baby syndrome and ototoxicity in puppies, respectively. Aminoglycosides are very often associated with nephrotoxicity, ototoxicity and neuromuscular blockage. Injudicious use of fluroquinones induces the onset of arthropathy in pups at the weight bearing joints. The most effective therapeutic measure in managing ADR is to treat the causative mediators, followed by supportive and symptomatic treatment. So, in this prospective review, we attempt to bring forth the commonly occurring adverse drug reactions, their classification, underlying mechanism, epidemiology, treatment and management as gleaned from the literature available till date and the different clinical cases observed by the authors.

Around 2.9–5.6 % of all The veterinarians and other health professional human patients admitted to hospitals suffer fromADRs commonly encounter inter-individual variations in and as many as 35% of them experience anADR during response to drug administration. Some patients their stay in hospital. The overall incidence of serious respond well to a particular therapy, while others fail to ADRs is 6.7 % and of fatal ADRs is 0.32 % in demonstrate idiosyncrasy. Often, small animal hospitalized patients [2]. A recent study in Turkey clinicians are informed by the dog owners or breeders revealed that maximum cases on ADR in animals were that their dogs are sensitive to a particular type of reported from vitamin-mineral-amino acid preparations medication. This variation in drug response among (39%), followed by antibacterials and anthelmentics individuals is due to the varied genetic make-up which (26%).

Unpredictable non-immunologic drug reactions There is no universally accepted definition for an include pseudoallergic, idiosyncratic and intolerance ADR. Most definitions are more or less similar to that [9]. explained by the World Health Organization (WHO) or Pseudoallergic reactions are mostly caused by the United States Food and Drug Administration direct activation of the mast cells and their degranu- (USFDA).As per the WHO definition, an adverse drug lation by drugs such as opiates, vancomycin and event is any response to a drug that is noxious and radiocontrast media.

Drug-induced threatening outcomes, hospitalization, disability, hemolysis with deficiency of glucose-6-phosphate congenital anomaly, and outcomes requiring dehydrogenase (G6PD) is a good example of idiosyncratic healthcare interventions [1, 3]. Some ADRs may be reaction.

Epidemiological data support the existence of Classification specific factors that increase the risk of ADR. Female ADRs are often classified as type-A occurring gender, infection with human immunodeficiency virus frequently and typically dose related and type-B, which (HIV), and herpes virus infection have been reported to is often, termed as idiosyncratic reactions.
