PROPRANOLOL S.R. - ORAL
COMMON BRAND NAME(S): Inderal LA
WARNING: Do not stop using this drug without first consulting your doctor. Your condition may become worse when the drug is suddenly stopped, especially if you have chest pain (angina) or heart disease (e.g., coronary artery disease, ischemic heart disease, high blood pressure). If your doctor decides you should no longer use this drug, you must gradually decrease your dose according to your doctor's instructions.
When gradually stopping this medication, it is recommended that you temporarily limit physical activity to decrease strain on the heart. Seek immediate medical attention if you develop: worsening chest pain, tightness/pressure in the chest, chest pain spreading to the jaw/neck/arm, unusual sweating, trouble breathing, or fast/irregular heartbeat.
USES: This medication is a beta blocker used to treat high blood pressure, irregular heartbeats, shaking (tremors), and other conditions as determined by your doctor. It 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.
This drug 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.
HOW TO USE: See also Warning section.
Take this medication by mouth usually once daily; or as directed by your doctor. Swallow the capsules whole; do not crush or chew the capsules.
The dosage is based on your medical condition and response to treatment.
Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. It is important to continue taking this medication even if you feel well.
This medication is used to help prevent chest pain or migraines. It should not be used to treat chest pain or migraines when they occur. Use other medications (e.g., nitroglycerin tablets placed under the tongue for chest pain, sumatriptan for migraines) to relieve sudden attacks as directed by your doctor. Consult your doctor or pharmacist for details.
It may take 1 to 2 weeks before you get the full benefit of this drug.
If you also take certain drugs to lower your cholesterol (bile acid-binding resins such as cholestyramine or colestipol), take propranolol at least 1 hour before or at least 4 hours after these medications.
Tell your doctor if your condition worsens (e.g., your routine blood pressure readings increase, your chest pain or migraines occur more often).
SIDE EFFECTS: See also Warning and Precautions sections.

This drug may reduce blood flow to your hands and feet, causing them to feel cold. Smoking may worsen this effect. Dress warmly and avoid tobacco use.
