This medication is used to treat high blood pressure in people with a certain adrenal gland tumor (pheochromocytoma). Metyrosine is used to prevent high blood pressure before and immediately after surgery to remove the tumor. It is also used long-term in people who cannot have the surgery. It is not used for other kinds of high blood pressure.Metyrosine prevents the tumor from making certain natural substances (catecholamines) that raise the blood pressure and make the heart beat faster. Lowering the amount of catecholamines lessens the risk of a very serious attack of high blood pressure (hypertensive crisis).
