Phenoxybenzamine, also known by its brand name Fenoxene, is a medication primarily used in the management of conditions such as pheochromocytoma (a rare tumor of the adrenal gland) and certain types of hypertension (high blood pressure). It belongs to a class of drugs called alpha-adrenergic blockers.
This medication is usually taken orally and is available in capsule form. Dosage and administration instructions should be followed closely as directed by a healthcare professional.
While phenoxybenzamine can be effective in managing certain conditions, it may also cause side effects, including dizziness, drowsiness, orthostatic hypotension (a sudden drop in blood pressure upon standing), nasal congestion, and fluid retention. Rarely, it may cause more serious side effects such as fast or irregular heartbeat, fainting, or allergic reactions.
Due to its mechanism of action and potential side effects, phenoxybenzamine should be used under the supervision of a healthcare provider who can monitor its effects and adjust the dosage as needed. It?s important to discuss any existing medical conditions, allergies, or medications you may be taking with your healthcare provider before starting phenoxybenzamine.
