What Is Propranolol 40mg?
Propranolol is a non-selective beta-blocker sold under the brand name Inderal. It works by blocking the effects of adrenaline on the heart and blood vessels, which slows the heart rate and lowers blood pressure. Propranolol 40mg tablets are FDA-approved to treat high blood pressure, chest pain (angina), essential tremor, and certain heart rhythm problems, and to help prevent migraine headaches. It is a prescription medication taken by mouth, usually two or more times daily as directed by your provider.
