Phenoxybenzamine

Drug Details

Phenoxybenzamine, known by the brand name Dibenzyline, is prescribed for managing high blood pressure and excessive sweating in adults with a type of adrenal gland tumor called pheochromocytoma. It is an alpha blocker that functions by relaxing and widening blood vessels, which allows blood to flow more easily and helps lower blood pressure. This also reduces sweating associated with pheochromocytoma. Typically, it is taken orally 2 to 4 times a day, but it is not intended for long-term use. Common side effects include low blood pressure when standing, fast heart rate, and nasal congestion. Phenoxybenzamine is available both as a brand-name and a more affordable generic option. Always consult your healthcare provider before starting any new medication.
