Inderal

Generic name: Propranolol

Usage of Inderal

Inderal is a beta-blocker. Beta-blockers affect the heart and circulation (blood flow through arteries and veins).

Inderal is used to treat tremors, angina (chest pain), hypertension (high blood pressure), heart rhythm disorders, and other heart or circulatory conditions. It is also used to treat or prevent heart attack, and to reduce the severity and frequency of migraine headaches.

Inderal LA are long-acting sustained-release capsules taken once daily. For angina treatment the dose can be gradually increased to three-to-seven-day intervals.

Inderal XL is supplied as an extended release capsule and is used for the treatment of hypertension. Inderal XL is taken once daily at bedtime.

Tell your doctor if you are pregnant or breastfeeding.
