Midrin (isometheptene mucate, dichloralphenazone and acetaminophen) is used to treat migraine headaches or severe tension headaches. It is a combination of three drugs: acetaminophen, a pain reliever and fever reducer; dichloralphenazone, a sedative; and isometheptene, a vasoconstrictor. Midrin is no longer manufactured, but equivalents (medications that contain the same drug combination) may be available. Consult your doctor and pharmacist. Common side effects include dizziness, drowsiness, and nausea.
The usual adult dosage of Midrin is two capsules at once, followed by one capsule every hour until relieved, up to 5 capsules within a 12-hour period. Midrin or equivalent medications may interact with blood thinners, isoniazid, or antidepressants. Acetaminophen is contained in many combination medicines. Read all labels carefully so you don't take too much acetaminophen. Tell your doctor all medications you are taking. During pregnancy, this medication should be used only when prescribed. Discuss the risks and benefits with your doctor. This medication passes into breast milk. Consult your doctor before breast-feeding.
