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).
To make sure you can safely take propranolol, tell your doctor if you have any of these other conditions:
- a muscle disorder;
- bronchitis, emphysema, or other breathing disorders;
- diabetes (propranolol can make it harder for you to tell when you have low blood sugar);
- low blood pressure;
- congestive heart failure;
- liver or kidney disease;
- a thyroid disorder;
- pheochromocytoma; or
- problems with circulation (such as Raynaud's syndrome).
FDA pregnancy category C. It is not known whether propranolol will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant while using this medication.
Propranolol can pass into breast milk and may harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
How should I take propranolol (Inderal LA)?
Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
You may take propranolol with or without food, but take it the same way each time.
Take the medicine at the same time each day.
Do not crush, chew, break, or open an extended-release capsule. Swallow it whole. Breaking or opening the pill may cause too much of the drug to be released at one time.
To be sure you get the correct dose, measure the liquid with a marked measuring spoon or medicine cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.
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.
Your blood pressure will need to be checked often. Visit your doctor regularly.
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.
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.
This medication can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using propranolol.
Store at room temperature away from moisture and heat.
