A
When a patient's immune system causes abnormal reactions to a medication, the patient has a medication allergy. Some medications cause unpredictable effects, such as idiosyncratic reactions, in which a patient overreacts or underreacts to a medication or has a reaction different from what is expected. Sudden constriction of bronchiolar muscles, edema of the pharynx and larynx, and severe wheezing and shortness of breath all characterize severe or anaphylactic reactions. A medication interaction occurs when one medication modifies the action of another medication.
