How to use acebutolol:
Use acebutolol as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Take acebutolol by mouth with or without food.
- Taking acebutolol at the same time each day will help you remember to take it.
- Continue to take acebutolol even if you feel well. Do not miss any doses.
- If you miss a dose of acebutolol, 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.
Ask your health care provider any questions you may have about how to use acebutolol.
Important safety information:
- Acebutolol may cause drowsiness, dizziness, or lightheadedness. These effects may be worse if you take it with alcohol or certain medicines. Use acebutolol with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
- Acebutolol may cause dizziness, lightheadedness, 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.
- Diabetes patients - Acebutolol may 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 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 more hungry. Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
- Do not suddenly stop taking acebutolol. Sharp chest pain, irregular heartbeat, and sometimes a heart attack may occur if you suddenly stop acebutolol. 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 acebutolol 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 acebutolol again.
- 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 acebutolol.
- If you have high blood pressure, do not use nonprescription products that contain stimulants. These products may include diet pills or cold medicines, including nasal sprays. Contact your doctor if you have any questions or concerns.
- If your doctor has instructed you to check your blood pressure and heart rate regularly, be sure to do so.
- Tell your doctor or dentist that you take acebutolol before you receive any medical or dental care, emergency care, or surgery.
- Use acebutolol with caution in the ELDERLY; they may be more sensitive to its effects.
- Acebutolol should be used with extreme caution in CHILDREN; safety and effectiveness in children have not been confirmed.
- PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using acebutolol while you are pregnant. Acebutolol is found in breast milk. Do not breast-feed while taking acebutolol.
