Propranolol is a beta-blocker that is used to treat angina (chest pain), hypertension (high blood pressure), heart rhythm disorders, and other heart or circulatory conditions. It is also used to reduce the risk of death after a heart attack.

Propranolol is also used to treat tremors of certain causes, and to prevent migraine headaches.

Hemangeol is used to treat a genetic condition called infantile hemangiomas in infants 5 weeks to 1 year old.

Propranolol may also be used for purposes not listed in this medication guide.

You should not use propranolol if you are allergic to it, or if you have:

• asthma;
• history of slow heart beats that have caused you to faint;
• severe heart failure (that required you to be in the hospital); or
• a serious heart condition such as "sick sinus syndrome" or heart block (2nd or 3rd degree, unless you have a pacemaker).

You should not use Hemangeol if you have pheochromocytoma (tumor of the adrenal gland). This medicine also should not be used in babies who weigh less than 4.4 pounds.

Tell your doctor if you have ever had:

• slow heartbeats, congestive heart failure;
• bronchitis, emphysema, or other breathing disorders;
• diabetes (propranolol can make it harder for you to tell when you have low blood sugar);
• liver or kidney disease;
• a thyroid disorder;
• pheochromocytoma (tumor of the adrenal gland);
• problems with circulation (such as Raynaud's syndrome); or
• if you smoke.

Tell your doctor if you are pregnant or breastfeeding.

Get emergency medical help if you have signs of an allergic reaction (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling).

Call your doctor at once if you have:

• slow or uneven heartbeats;
• a light-headed feeling, like you might pass out;
• wheezing or trouble breathing;
• sudden weakness, vision problems, or loss of coordination (especially in a child with hemangioma that affects the face or head);
• cold feeling in your hands and feet;
• depression, confusion, hallucinations;
• heart problems--swelling, rapid weight gain, feeling short of breath;
• low blood sugar--headache, hunger, sweating, irritability, dizziness, fast heart rate, and feeling anxious or shaky; or
• low blood sugar in a baby--pale skin, blue or purple skin, sweating, fussiness, crying, not wanting to eat, feeling cold, drowsiness, weak or shallow breathing (breathing may stop for short periods), seizure (convulsions), or loss of consciousness.

Common side effects may include:

• dizziness, tiredness;
• nausea, vomiting, diarrhea, constipation, stomach cramps;
• sleep problems (insomnia); or
• runny or stuffy nose, cough, sore throat, hoarse voice.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Avoid drinking alcohol. It may increase your blood levels of propranolol.
