What special precautions should I follow?  

Before taking acetohexamide,

• tell your doctor and pharmacist if you are allergic to acetohexamide or any other drugs.
• tell your doctor and pharmacist what prescription and nonprescription medications you are taking, including vitamins.
• tell your doctor if you have or have ever had kidney, liver, thyroid, or heart disease or a severe infection.
• tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking acetohexamide, call your doctor immediately. Acetohexamide should not be taken by pregnant women.
• if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking acetohexamide.
• plan to avoid unnecessary or prolonged exposure to sunlight and to wear protective clothing, sunglasses, and sunscreen. Acetohexamide may make your skin sensitive to sunlight.

What special dietary instructions should I follow?  

Be sure to follow all exercise and dietary recommendations made by your doctor or dietitian. It is important to eat a healthful diet.

Alcohol may cause a decrease in blood sugar. Ask your doctor about the safe use of alcoholic beverages while you are taking acetohexamide.

What should I do if I forget a dose?  

Before you start taking acetohexamide, ask your doctor what to do if you forget to take a dose. Write down these directions so you can refer to them later.

As a general rule, take the missed dose as soon as you remember it unless it is almost time for the next dose. Do not take a double dose to make up for a missed one.
