Acebutolol is used to treat hypertension (high blood pressure) and heart rhythm disorders.

Directions for use

  • Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not use this medicine in larger or smaller amounts or for longer than recommended.

  • If you need surgery, tell the surgeon ahead of time that you are using acebutolol. You may need to stop using the medicine for a short time.

  • Your blood pressure will need to be checked often.

  • You should not stop using acebutolol suddenly. Stopping suddenly may make your condition worse.
