General Information

Demser (Metyrosine) is indicated to treat pheochromocytoma or tumor of the adrenal gland. This is given before surgery to control the condition and also given when surgery is not possible. This drug is given to those with high blood pressure who are experiencing this condition.

Demser (Metyrosine) is not used for other kinds of high blood pressure. This is being used for long-term medication.

 

How does Demser (Metyrosine) work?
