Inderal (Generic)

Inderal (Propranolol) is a beta-adrenergic blocking agent. It works by slowing down the heart and reducing blood pressure, which helps it pump more efficiently and reduces the workload on the heart. It can then also interfere with the action of adrenalin and other similar chemicals in the brain preventing migraine headaches. Inderal also marketed as: Deralin, Propranolol, Propanolol.

Uses

Propranolol (proe-PRAN-oh-lol) is used in the treatment of high blood pressure, angina pectoris (chest pain, usually caused by lack of oxygen to the heart due to clogged arteries), alterations to heart rhythm, prevention of migraine headache, hereditary tremors, hypertrophic subaortic stenosis (a condition related to exertional angina), and tumors of the adrenal gland. It is also used to reduce the risk of death from recurring heart attack.

How to take

Take Propranolol orally with or without food, but it should be taken at the same time daily and consistently either on an empty stomach or with food. Do not take antacids containing aluminum within 2 hours of taking Propranolol. Do not miss any doses.

Side effects

Tell your doctor if any of these Propranolol symptoms are severe or do not go away: dizziness or lightheadedness, difficulty sleeping, excessive tiredness, upset stomach, vomiting, rash, diarrhea, constipation. If you experience any of the following Propranolol symptoms, call your doctor immediately: difficulty breathing, sore throat, unusual bleeding, swelling of the feet or hands; unusual weight gain, chest pain, slow, irregular heartbeat. Symptoms of overdose can then include difficulty breathing, especially when lying down; lightheadedness, especially upon standing; pale or blue skin; seizures (convulsions); shortness of breath; swelling of ankles; unconsciousness, possibly leading to lack of heartbeat or breathing; very slow heart rate; wheezing. If you suspect an overdose of Propranolol, seek medical attention immediately.

Precaution

Do NOT use Propranolol if: You are allergic to any ingredient in Propranolol; You have a very slow heartbeat and heart block; had a heart attack and have very low blood pressure or uncontrolled heart failure or shock caused by heart failure; You have asthma or Raynaud phenomenon; You are taking mibefradil. Before taking Propranolol, tell your doctor if you have or have ever had asthma or other lung disease; heart, liver, or kidney disease; diabetes; severe allergies; or thyroid tribulations. Contact your doctor or health care provider right away if any of these apply to you. Propranolol can then cause drowsiness, dizziness, or lightheadedness. These effects can then be worse if you take it with alcohol or certain medicines. Use Propranolol with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it. Propranolol can then cause dizziness, lightheadedness, or fainting; alcohol, hot weather, exercise, or fever can then increase these effects. To prevent them, sit up or stand slowly, especially in the morning. Sit or lie down at the first sign of any of these effects. Check with your doctor before drinking alcohol while you are taking Propranolol. 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 can then not feel "normal." Tell your doctor if you develop any new symptoms. Propranolol can then mask the signs of hyperthyroidism (overactive thyroid). If you have an overactive thyroid and stop taking Propranolol too suddenly, symptoms of hyperthyroidism (eg, fast heartbeat) can then occur. Patients with a history of severe allergic reactions can then be more sensitive to allergens while taking Propranolol. These patients can then not respond to the usual dose of epinephrine (adrenalin). Diabetes patients - Propranolol can then hide signs of low blood sugar, such as a rapid heartbeat. Be sure to watch for other signs of low blood sugar. Low blood sugar can then make you anxious, sweaty, weak, dizzy, drowsy, or faint. It can then also make your vision change; give you a headache, chills, or tremors; or make you hungrier. Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine. Tell your doctor or dentist that you take Propranolol before you receive any medical or dental care, emergency care, or surgery. Propranolol can then interfere with certain lab tests, which can incorporate the glaucoma screening test. Be sure your doctor and lab personnel know you are taking Propranolol. Lab tests, which can incorporate blood pressure and heart function tests, can then be performed while you use Propranolol. These tests can then be used to monitor your condition or check for side effects. Propranolol helps control your condition but will not cure it. Continue to take Propranolol even if you feel well. If you suddenly stop taking Propranolol, you can then experience withdrawal symptoms, which can incorporate worsening chest pain along with possible heart attack. Talk to your doctor before using salt substitutes containing potassium. If your doctor prescribes a low-salt or low-sodium diet, follow these directions carefully. Tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. Propranolol is found in breast milk. If you become pregnant while taking Propranolol, call your doctor.

Drug interactions

Tell your doctor what prescription and nonprescription meds you are taking, especially cimetidine (Tagamet); meds for migraine headaches, asthma, allergies, colds, or pain; other meds for heart disease or high blood pressure; reserpine; vitamins, dietary supplements, or herbal preparations. Antiarrhythmics (eg, amiodarone, flecainide, quinidine), antipsychotics (eg, chlorpromazine, haloperidol), bupivacaine, calcium channel blockers (eg, mibefradil, nifedipine, verapamil), cimetidine, ketanserin, mefloquine, or thioamines (eg, tapazole) because potentially life-threatening heart-related side effects can then occur, which can incorporate very slow heart rate; abnormal heartbeat; lightheadedness, especially upon standing; difficulty breathing, especially when lying down; loss of function in the heart and lungs; and swelling of ankles. Barbiturates (eg, phenobarbital), clonidine, phenytoin, rifampin, or thyroid hormones (eg, levothyroxine) because they can then decrease Propranolol's effectiveness. Certain stimulants (adrenalin, pseudoephedrine), hydralazine, insulin, lidocaine, quinazolines (eg, doxazosin), rizatriptan, or theophylline because their actions and the risk of their side effects can then be increased by Propranolol.

Missed dose

If you miss a dose of Propranolol, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Storage
