What is the most important information I should know about propranolol (Inderal)?

You should not use this medication if you are allergic to propranolol, if you have asthma, a slow heart rate, or a serious heart condition such as "sick sinus syndrome" or "AV block" (unless you have a pacemaker).

If you need surgery, tell the surgeon ahead of time that you are using propranolol. You may need to stop using the medicine for a short time.

Do not skip doses or stop using propranolol without first talking to your doctor. You may need to use less and less before you stop the medication completely.

Avoid drinking alcohol. It may increase your blood levels of propranolol.

Propranolol is only part of a complete program of treatment for hypertension that may also include diet, exercise, and weight control. Follow your diet, medication, and exercise routines very closely if you are being treated for hypertension.

If you are being treated for high blood pressure, keep using this medication even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.
