Medical Dictionary
adverse effect
Pronunciation (ad′vers e-fekt′)
- a result of drug or other therapy in addition to or in extension of the desired therapeutic effect; usually but not necessarily, connoting an undesirable effect. Although technically the therapeutic effect carried beyond the desired limit (e.g., a hemorrhage from an anticoagulant) is a side effect, the term more often refers to pharmacologic results of therapy unrelated to the usual objective (e.g., a development of signs of Cushing syndrome with steroid therapy).
Syn: side effect
