Phenoxybenzamine

Phenoxybenzamine is used to treat episodes of high blood pressure and sweating related to pheochromocytoma. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Phenoxybenzamine comes as a capsule to take by mouth. It usually is taken two or three times a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take phenoxybenzamine exactly as directed.
