Propranolol, which treats high blood pressure, irregular heart rhythms, chest pain, and other heart symptoms, is also approved by the U. Food and Drug Administration (FDA) for preventing migraine attacks. Propranolol falls into the beta-blocker class of medications. Beta blockers reduce the frequency of migraine attacks in 60 to 80 percent of people. It is not clear, however, if propranolol affects active migraine, so it should not be taken to stop migraine attacks already in progress. Propranolol is available in multiple formulations, including tablets, liquid, and a long-acting time-release capsule. Propranolol is the active ingredient in Inderal LA, Inderal XL, and Inno Pran XL. Propranolol works by blocking certain receptors, known as beta receptors, in blood vessels. Take this medicine only as directed by your doctor.

Show More This medication is a beta blocker used to treat high blood pressure, irregular heartbeats, shaking (tremors), and other conditions. It is used after a heart attack to improve the chance of survival. It is also used to prevent migraine headaches and chest pain (angina). The usual initial dosage is 40 mg Inderal twice daily, whether used alone or added to a diuretic. Dosage may be increased gradually until adequate blood pressure control is achieved. The usual maintenance dosage is 120 mg to 240 mg per day. In some instances a dosage of 640 mg a day may be required. The time needed for full antihypertensive response to a given dosage is variable and may range from a few days to several weeks. While twice-daily dosing is effective and can maintain a reduction in blood pressure throughout the day, some patients, especially when lower doses are used, may experience a modest rise in blood pressure toward the end of the 12-hour dosing interval. This can be evaluated by measuring blood pressure near the end of the dosing interval to determine whether satisfactory control is being maintained throughout the day.
