Propranolol ER(Propranolol ER)
Propranolol ER Overview
Propranolol ER is a beta blocker used to treat high blood pressure, irregular heartbeats, shaking (tremors), and other conditions as determined by your doctor. Propranolol ER is used after a heart attack to improve survival. It is also used to prevent migraine headaches and chest pain (angina). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. Preventing chest pain can help improve your ability to exercise. Propranolol ER works by blocking the action of certain natural chemicals in your body (such as epinephrine) that affect the heart and blood vessels. This effect reduces heart rate, blood pressure, and strain on the heart.

Your condition may become worse when the drug is suddenly stopped, especially if you have chest pain (angina) or heart disease (such as coronary artery disease, ischemic heart disease, high blood pressure). If your doctor decides you should no longer use Propranolol ER, you must gradually decrease your dose according to your doctor's instructions.
