Generic Name: pindolol (PIN-doe-lol)
Brand Name: Generic only. No brands available.
Do not suddenly stop taking pindolol. Sharp chest pain, irregular heartbeat, and sometimes heart attack may occur if you suddenly stop pindolol. The risk may be greater if you have certain types of heart disease. Your doctor should slowly lower your dose over several weeks if you need to stop taking it. This should be done even if you only take pindolol for high blood pressure. Heart disease is common and you may not know you have it. Limit physical activity while you are lowering your dose. If new or worsened chest pain or other heart problems occur, contact your doctor right away. You may need to start taking pindolol again.
Pindolol is used for:
Treating high blood pressure. It may be used alone or with other medicines. It may also be used for other conditions as determined by your doctor.
Pindolol is a beta-adrenergic blocking agent. 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.
Do NOT use pindolol if:
- you are allergic to any ingredient in pindolol
- you have a very slow heartbeat, heart block, uncontrolled heart failure, or shock caused by serious heart problems
- you have asthma
- you are taking mibefradil
Contact your doctor or health care provider right away if any of these apply to you.

- if you are pregnant, planning to become pregnant, or are breast-feeding
- if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
- if you have allergies to medicines, foods, or other substances

- Catecholamine-depleting medicines (eg, reserpine), cimetidine, digoxin, diltiazem, disopyramide, flecainide, ketanserin, mefloquine, mibefradil, phenothiazines (eg, thioridazine), or verapamil because serious side effects, such as very slow heart rate, very low blood pressure, fainting, severe dizziness, or light-headedness when standing, may occur
- Indomethacin because it may decrease pindolol's effectiveness
- Fingolimod, insulin, meglitinide antidiabetics (eg, nateglinide), or quinazolines (eg, alfuzosin) because the risk of their side effects may be increased by pindolol
- Sympathomimetics (eg, albuterol) or theophylline because their effectiveness may be decreased by pindolol
- Epinephrine because the effectiveness may be decreased by pindolol. The risk of side effects, such as high blood pressure and slow heartbeat, may be increased

Important safety information:
- Pindolol may cause dizziness or light-headedness. These effects may be worse if you take it with alcohol or certain medicines. Use pindolol with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
- Pindolol may cause dizziness, light-headedness, or fainting; alcohol, hot weather, exercise, or fever may 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.
- 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.
- It may take up to 2 to 4 weeks to get the full benefit from pindolol. Do not stop using pindolol or change your dose of pindolol without checking with your doctor.
- Pindolol may mask the signs of hyperthyroidism (overactive thyroid). If thyroid patients stop taking these medicines too suddenly, symptoms of hyperthyroidism (eg, a rapid pulse) may occur.
- 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 pindolol.
- If you have high blood pressure, do not use nonprescription products that contain stimulants. These products may include diet pills or cold medicines. Contact your doctor if you have any questions or concerns.
- Pindolol may interfere with the glaucoma screening test.
- Diabetes patients - Pindolol may mask signs of low blood sugar such as a rapid heartbeat. Be sure to watch for other signs of low blood sugar. Low blood sugar may make you anxious, sweaty, weak, dizzy, drowsy, or faint. It may also make your vision change; give you a headache, chills, or tremors; or make you hungrier. Pindolol may also affect blood sugar levels. Check blood glucose levels closely. Ask your doctor before you change the dose of your diabetes medicine.
- Tell your doctor or dentist that you take pindolol before you receive any medical or dental care, emergency care, or surgery.
- Do not suddenly stop taking pindolol without first consulting with your doctor. Severe chest pain, irregular heartbeat, and sometimes heart attack may occur if you suddenly stop pindolol. The risk may be greater if you have certain types of heart disease. If your doctor decides you should no longer take pindolol, the dosage should be gradually reduced according to your doctor's instructions. If new or worsened chest pain or other heart problems develop, contact your doctor right away. You may need to start taking pindolol again.
- Lab tests, including blood pressure, may be performed while you use pindolol. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
- Use pindolol with extreme caution in CHILDREN; safety and effectiveness have not been confirmed.
