Precautions & warnings
What should I know before using Sectral® (acebutolol)?
Before using this drug, tell your doctor if:
- You are pregnant or breastfeeding. This is because, while you are expecting or feeding a baby, you should only take medicines on the recommendation of a doctor.
- You are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, such as herbal and complementary medicines.

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 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.
