Propranolol: Uses, Dosage, Side Effects, and Warnings

What is Propranolol?

Propranolol is a beta-blocker. Beta-Blockers are a class of drugs that are mainly used to manage abnormal heart rhythms, they are also used to protect the heart from a second heart attack after a patient has suffered from a first heart attack [1]. They affect the heart and blood flow through the blood vessels.

Propranolol slows down your heart rate and aids the circulation of blood throughout your body. It is usually prescribed for patients with high blood pressure [2] (hypertension). It is also used to treat anxiety and migraine. It is an oral medication that comes in either tablet or liquid form.  Hemangeol, the liquid form of propranolol, is administered to infants between the ages of 5 weeks and 1 year to treat a congenital condition called Infantile Hemangiomas. Hemangiomas are caused by blood vessels clumping together abnormally. These clumps of blood vessels form benign growths that can cause ulcers and red marks on the skin and other severe complications in the body.
