How does this medication work? What will it do for me?
Pindolol belongs to the class of medications called beta-blockers. It is used to treat high blood pressure and to prevent angina (chest pain). For treatment of high blood pressure, pindolol may be used alone or in combination with other medications that reduce high blood pressure, particularly thiazide diuretics (water pills). Pindolol works by decreasing the demands on the heart.

How should I use this medication?
The recommended dose of pindolol ranges from 5 mg to 45 mg daily, depending on the needs of the person taking the medication. It should be taken with food.
For treatment of high blood pressure, the dose of pindolol is usually started at 5 mg twice daily and increased gradually until the best dose is found. When the dose is less than 30 mg per day, it is taken in 2 divided doses. Doses greater than 30 mg per day are taken in 3 divided doses.
For treatment of angina, the starting dose is 5 mg 3 times a day with food. If the desired response is not reached in 1 to 2 weeks, the dosage may be increased, up to a maximum of 40 mg per day.
