Which class of drugs is most likely to cause adverse drug reactions?

The class of drugs that is most likely to cause adverse drug reactions includes all drug classes, as all medications, regardless of their specific therapeutic use, have the potential to elicit side effects or adverse reactions in certain individuals. Various factors contribute to this risk, such as the patient's overall health, concurrent medications, genetic factors, dosing, and duration of therapy.

Analgesics, for instance, can lead to gastrointestinal, renal, or cardiovascular issues, while antibiotics may cause allergic reactions, gastrointestinal disturbances, or interactions with other medications. Corticosteroids are associated with a range of side effects, including metabolic changes, immune suppression, and psychological effects. Given the diverse mechanisms by which different classes of drugs operate and the variability in individual responses, it is crucial to recognize that no single class is exempt from the risk of adverse reactions. Thus, the understanding that all drug classes can produce adverse effects best captures the comprehensive risk associated with pharmacotherapy.
