What should I watch for while taking acetohexamide?
Visit your prescriber or health care professional for regular checks on your progress. Learn how to monitor blood or urine sugar and urine ketones regularly. Check with your prescriber or health care professional if your blood sugar is high, you may need a change of dose of acetohexamide. Do not skip meals.

Ask your prescriber or health care professional if you should avoid alcohol. If you have mild symptoms of low blood sugar, eat or drink something containing sugar at once and contact your prescriber or health care professional.

Make sure family members know that you can choke if you eat or drink when you have serious symptoms of low blood sugar, such as seizures or unconsciousness. They must get medical help at once.
