Frequently Asked Questions
You should not use this medicine if you have asthma, very slow heart beats, or a serious heart condition such as "sick sinus syndrome" or "AV block" (unless you have a pacemaker).
Babies who weigh less than 4.5 pounds should not be given Hemangeol oral liquid.
Propranolol is a beta-blocker. Beta-blockers affect the heart and circulation (blood flow through arteries and veins).
Propranolol 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.
Hemangeol (propranolol oral liquid 4.28 milligrams) is given to infants who are at least 5 weeks old to treat a genetic condition called infantile hemangiomas. Hemangiomas are caused by blood vessels grouping together in an abnormal way. These blood vessels form benign (non-cancerous) growths that can develop into ulcers or red marks on the skin. Hemangiomas can also cause more serious complications inside the body (in the liver, brain, or digestive system).
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:
- very slow heart beats that have caused you to faint; or
- a serious heart condition such as "sick sinus syndrome" or "AV block" (unless you have a pacemaker).
Babies who weigh less than 4.5 pounds should not be given Hemangeol oral liquid.
To make sure propranolol is safe for you, tell your doctor if you have:
