Adverse Drug Reaction (ADR)

An Adverse Drug Reaction (ADR) refers to a harmful or unpleasant physiological reaction that occurs as a result of taking a medication. These reactions, which are often referred to as side effects, can vary in severity from mild to severe and can occur immediately after taking the medication or only after prolonged use. ADRs can significantly impact a patient’s quality of life and may sometimes lead to discontinuation of the medication. It’s important for healthcare providers to monitor for potential ADRs and for patients to report any unexpected or worsening symptoms to their healthcare provider.
