Inderal is used for treating high blood pressure or atrial fibrillation. It is used in patients with angina to decrease angina frequency and increase exercise tolerance. It is used to decrease the risk of heart death in certain patients who have survived a heart attack. It is used to manage certain types of tremors, a heart condition called hypertrophic subaortic stenosis, or certain symptoms of pheochromocytoma (an adrenal tumor). It is used to prevent migraine headaches. Inderal is a beta-blocker. It works by slowing down the heart and decreasing the amount of blood it pumps out. This helps to decrease blood pressure, helps the heart pump more efficiently, and reduces the workload on the heart. Exactly how Inderal works to treat migraines or tremors is not known.

Important safety information:
- Inderal may cause drowsiness, dizziness, lightheadedness, or vision changes. These effects may be worse if you take it with alcohol or certain medicines. Use Inderal with caution. Do not drive or perform other possible unsafe tasks until you know how you react to it.
- Check with your doctor before you drink alcohol while you are taking Inderal; it may increase the risk of Inderal’s side effects.
- Do NOT take more than the recommended dose without checking with your doctor.
- Patients who take medicine for high blood pressure often feel tired or run down for a few weeks after starting treatment. Be sure to take your medicine even if you may not feel “normal.” Tell your doctor if you develop any new symptoms.
- Tell your doctor or dentist that you take Inderal before you receive any medical or dental care, emergency care, or surgery.
- If you have a history of any severe allergic reaction, talk with your doctor. You may be at risk of an even more severe allergic reaction if you come into contact with the substance that caused your allergy. Some medicines used to treat severe allergies may also not work as well while you are using Inderal.
- Inderal may lower your blood sugar levels. This is most likely to happen in infants and children, or in patients who have diabetes or kidney problems. It may also occur after prolonged physical activity or during fasting. Low blood sugar may make you anxious, sweaty, weak, dizzy, drowsy, or faint. It may also make your heart beat faster; make your vision change; give you a headache, chills, or tremors; or make you more hungry. It is a good idea to carry a reliable source of glucose (eg, tablets or gel) to treat low blood sugar. If this is not available, you should eat or drink a quick source of sugar like table sugar, honey, candy, orange juice, or non-diet soda. This will raise your blood sugar level quickly. Tell your doctor right away if this happens.
- Diabetes patients – Inderal may hide signs of low blood sugar, such as a rapid heartbeat. Be sure to watch for other signs of low blood sugar. Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
- Inderal may interfere with certain lab tests, including glaucoma screening and dobutamine stress echocardiography. Be sure your doctor and lab personnel know you are taking Inderal.
- Lab tests, including blood pressure and heart function, may be performed while you use Inderal. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
- Use Inderal with caution in the elderly; they may be more sensitive to its effects.
- Caution is advised when using Inderal in children; they may be more sensitive to its effects, especially low blood sugar levels or shortness of breath.
- Pregnancy and breast-feeding: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Inderal while you are pregnant. Inderal is found in breast milk. If you are or will be breast-feeding while you use Inderal, check with your doctor. Discuss any possible risks to your baby.
If you stop taking Inderal suddenly, you may have withdrawal symptoms. These may include worsening chest pain along with possible heart attack.
