WARNING Phenoxybenzamine hydrochloride capsule-induced alpha -adrenergic blockade leaves beta -adrenergic receptors unopposed. Compounds that stimulate both types of receptors may, therefore, produce an exaggerated hypotensive response and tachycardia.
ADVERSE REACTIONS The following adverse reactions have been observed, but there are insufficient data to support an estimate of their frequency. Autonomic Nervous System * : Postural hypotension, tachycardia, inhibition of ejaculation, nasal congestion, miosis. * These so-called "side effects" are actually evidence of adrenergic blockade and vary according to the degree of blockade. Miscellaneous: Gastrointestinal irritation, drowsiness, fatigue. To report SUSPECTED ADVERSE REACTIONS, contact Prasco Laboratories at 1-866-525-0688 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
