Metopirone (metyrapone USP) is a diagnostic drug for testing hypothalamic-pituitary ACTH function. Common side effects include nausea, upset stomach, headache, dizziness, or drowsiness.
Metopirone is usually administered as a single-dose test. Adults and children are given the same 30 mg/kg dose (maximum 3 g Metopirone) at midnight with yogurt or milk. A blood sample is taken early the following morning. Metopirone may interact with acetaminophen, cyproheptadine, estrogens, and hydantoins (such as phenytoin). Do not drive, use machinery, or do any activity that requires alertness or clear vision while taking Metopirone. Avoid alcoholic beverages. Metopirone should be used during pregnancy only if clearly needed. It is not known if Metopirone passes into breast milk. Consult your doctor before breastfeeding.
