Repaglinide is used alone or with other medications to control high blood sugar along with a proper diet and exercise program. It is used in people with type 2 diabetes. Controlling high blood sugar helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. Proper control of diabetes may also lessen your risk of a heart attack or stroke. It works by stimulating the body to produce more insulin. Insulin is a natural substance that allows the body to properly use sugar from the diet.
Read the Patient Information leaflet if one is available from your pharmacist before you start using repaglinide and each time you get a refill. If you have any questions, consult your doctor or pharmacist.

Repaglinide can cause low blood sugar (hypoglycemia) especially if you are taking other medicines for diabetes. Consuming large quantities of alcohol, not getting enough calories from food, or doing unusually heavy exercise may also lead to low blood sugar. Symptoms may include chills, cold sweat, dizziness, drowsiness, shaking, fast heartbeat, weakness, headache, fainting, tingling of the hands or feet, or hunger. It is a good habit to carry glucose tablets or gel to treat low blood sugar. If you don't have these reliable forms of glucose, raise your blood sugar quickly by eating a quick source of sugar such as table sugar, honey, candy, or drinking a glass of fruit juice or non-diet soda. Check with your doctor or pharmacist to find out what you should do if you miss a meal.
Symptoms of high blood sugar (hyperglycemia) include thirst, increased urination, confusion, drowsiness, flushing, rapid breathing, and fruity breath odor. If these symptoms occur, tell your doctor immediately. Your doctor may need to adjust your diabetes medication(s).
A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any of the following symptoms of a serious allergic reaction: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
