True or False: An adverse drug reaction is always life-threatening.

An adverse drug reaction is not always life-threatening; thus, the statement is false. Adverse drug reactions can range from mild to severe, and while some may pose significant risks to a patient's health or life, many others are manageable and do not require immediate intervention. For example, common adverse reactions can include side effects like gastrointestinal upset or mild allergic reactions, which, although undesirable, are not life-threatening.

In veterinary pharmacology, understanding the spectrum of potential adverse effects is crucial. Not every drug interaction or side effect will escalate to a life-threatening condition, and clinical assessment often helps determine the severity of the reaction and the appropriate response. This knowledge is essential for veterinarians when prescribing medications and monitoring their effects on animal patients.
