What is the most important information I should know about pindolol (Visken)?

You should not use this medication if you are allergic to pindolol, or if you have asthma, certain heart conditions (especially second or third degree heart block), heart failure, or severe slow heart rate.

Before taking pindolol, tell your doctor if you have bronchitis, emphysema, diabetes, heart disease, congestive heart failure, slow heart rate, coronary artery disease, low blood pressure, liver or kidney disease, depression, or a thyroid disorder.

Do not skip doses or stop taking pindolol without first talking to your doctor. Stopping suddenly may make your condition worse, and it can cause serious or life-threatening side effects. You will need to stop using pindolol gradually. Follow your doctor's instructions.

Pindolol 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.

Hypertension often has no symptoms, so you may not even feel that you have high blood pressure. Continue using this medicine as directed, even if you feel well. You may need to use blood pressure medication for the rest of your life.
