Drug-induced hypertension is an uncommon cause of hypertension. Many classes of medication can induce hypertension in some individuals. Medications that are sympathomimetic, in particular, are well known for causing hypertension. Examples of such drugs are amphetamines and decongestants. Other classes of drugs commonly associated with inducing hypertension are corticosteroids, stimulants, estrogens, and immunosuppressants. Pre-existing hypertension and renal failure are risk factors for serious complications from drug-induced hypertension. Drug-induced hypertension is treated with discontinuation or dose reduction of the offending drug.
