Generic Name: repaglinide/metformin (re-PAG-li-nide/met-FOR-min)
Brand Name: PrandiMet
PrandiMet may rarely cause a serious and sometimes fatal condition called lactic acidosis. Most of these cases have occurred in diabetic patients who also have certain kidney problems. The risk of lactic acidosis may be greater if you have liver problems, kidney problems, or heart failure. The risk may also be greater in patients who are elderly or drink alcohol. Lab tests, including kidney function, may be performed while you take PrandiMet.
Do not begin to take PrandiMet if you are older than 80 years old unless lab tests show that you do not have decreased kidney function. Do not take it if you have a severe infection, have low blood oxygen levels, or are dehydrated. Tell your doctor you take PrandiMet before you have any surgery or lab procedures.
Contact your doctor right away if you notice symptoms such as muscle pain or tenderness; unusual drowsiness, dizziness, or light-headedness; slow or irregular heartbeat; fast or difficult breathing; unusual stomach discomfort; or unusual weakness or tiredness. Contact your doctor right away if you start to feel unusually cold, or if you have a general feeling of being unwell.
PrandiMet is used for:
Treating type 2 (non-insulin-dependent) diabetes. It is used along with diet and exercise. It may be used alone or with other antidiabetic medicines.
PrandiMet is a meglitinide and biguanide combination. It works by decreasing the amount of sugar absorbed from food by the intestines and reduces the amount of sugar made in the liver. It also increases the amount of insulin in the blood and helps your body to use insulin and sugar more efficiently. This helps to control blood sugar levels.
Do NOT use PrandiMet if:
- you are allergic to any ingredient in PrandiMet
- you have type 1 diabetes (insulin-dependent diabetes)
- you have a severe infection, low blood oxygen levels, kidney or liver problems, high blood ketone or acid levels (eg, diabetic ketoacidosis), or severe dehydration
- you have had a stroke or a recent heart attack, or you are in shock
- you are 80 years old or older, unless lab tests show that you do not have decreased kidney function
- you will be having surgery or certain lab procedures
- you are taking gemfibrozil or NPH insulin
Contact your doctor or health care provider right away if any of these apply to you.

This may not be a complete list of all interactions that may occur. Ask your health care provider if PrandiMet may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
How to use PrandiMet:

- An extra patient leaflet is available with PrandiMet. Talk to your pharmacist if you have questions about this information.
- Take PrandiMet by mouth at least 15 to 30 minutes before each meal. If you skip a meal, do not take the dose for the skipped meal.
- Take PrandiMet on a regular schedule to get the most benefit from it. Taking PrandiMet at the same time each day will help you remember to take it.
- Continue to take PrandiMet even if you feel well. Do not miss any doses.
- If you miss a dose of PrandiMet, 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 PrandiMet.
Important safety information:
- Dizziness may occur while you are taking PrandiMet. This effect may be worse if you take it with alcohol or certain medicines. Use PrandiMet with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
- Follow the diet and exercise program given to you by your health care provider.
- Do not drink large amounts of alcohol while you use PrandiMet. Talk to your doctor or health care provider before you drink alcohol while you use PrandiMet.
- Tell your doctor or dentist that you take PrandiMet before you receive any medical or dental care, emergency care, or surgery.
- Be careful not to become dehydrated, especially during hot weather or while you are being active. Dehydration may increase the risk of PrandiMet's side effects.
- If vomiting or diarrhea occurs, you will need to take care not to become dehydrated. Contact your doctor for instructions.
- Carry an ID card at all times that says you have diabetes. Check your blood sugar levels as directed by your doctor. If they are often higher or lower than they should be and you take PrandiMet exactly as prescribed, tell your doctor.
- PrandiMet may cause low blood sugar. Low blood sugar may be more likely to occur if you skip a meal, exercise heavily, or drink alcohol. It may also be more likely if you take PrandiMet along with certain medicines for diabetes (eg, sulfonylureas, insulin). Low blood sugar may make you anxious, sweaty, weak, dizzy, drowsy, or faint. It may also make your heart beat faster; make your vision change; give you a headache, chills, or tremors; or make you hungrier. It is a good idea to carry a reliable source of glucose (eg, tablets or gel) to treat low blood sugar. If this is not available, you should eat or drink a quick source of sugar like table sugar, honey, candy, orange juice, or non-diet soda. This will raise your blood sugar level quickly. Tell your doctor right away if this happens. To prevent low blood sugar, eat meals at the same time each day and do not skip meals.
- Fever, infection, injury, or surgery may increase your risk for high or low blood sugar levels. If any of these occur, check your blood sugar closely and tell your doctor right away.
- PrandiMet may commonly cause stomach upset, indigestion, nausea, vomiting, or diarrhea at the beginning of treatment. If you develop unusual or unexpected stomach problems, or if you develop stomach problems later during treatment, contact your doctor at once. This may be a sign of lactic acidosis.
- Lab tests, including kidney function, fasting blood glucose, hemoglobin A1c, and blood counts, may be performed while you use PrandiMet. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
- Use PrandiMet with caution in the ELDERLY; they may be more sensitive to its effects. Low blood sugar levels may also be more difficult to recognize in elderly patients.
- PrandiMet should not be used 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 PrandiMet while you are pregnant. It is not known if this medicine is found in breast milk. Do not breast-feed while taking PrandiMet.
When used for long periods of time, PrandiMet may not work as well. If your blood sugar has been under control and then becomes hard to manage, contact your doctor. Do not change the dose of your medicine without checking with your doctor.
