What is metformin and repaglinide (Prandimet)?
Metformin and repaglinide are oral diabetes medications that help control blood sugar levels. Repaglinide works by causing the pancreas to produce insulin. Metformin works by decreasing glucose (sugar) production in the liver and decreasing absorption of glucose by the intestines.
The combination of metformin and repaglinide is used together with diet and exercise to treat type 2 (non-insulin dependent) diabetes.
Metformin and repaglinide may also be used for other purposes not listed in this medication guide.
What are the possible side effects of metformin and repaglinide (Prandimet)?
Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
Hypoglycemia, or low blood sugar, is the most common side effect of metformin and repaglinide. Symptoms include headache, hunger, weakness, sweating, tremors, irritability, trouble concentrating, rapid breathing, fast heartbeat, fainting, or seizure (severe hypoglycemia can be fatal). Carry hard candy or glucose tablets with you in case you have low blood sugar.
This medication may cause lactic acidosis (a build-up of lactic acid in the body, which can be fatal). Lactic acidosis can start slowly and get worse over time. Get emergency medical help if you have even mild symptoms of lactic acidosis, such as:
- muscle pain or weakness;
- numb or cold feeling in your arms and legs;
- trouble breathing;
- feeling dizzy, light-headed, tired, or very weak;
- stomach pain, nausea with vomiting; or
- slow or uneven heart rate.
Less serious side effects may include:
- nausea, diarrhea; or
- runny or stuffy nose, sneezing, cough, or cold symptoms.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

What is the most important information I should know about metformin and repaglinide (Prandimet)?
You should not use this medication if you are allergic to metformin (Glucophage) or repaglinide (Prandin), if you have kidney disease or type 1 diabetes, or if you are in a state of diabetic ketoacidosis (call your doctor for treatment with insulin).
You should not use metformin and repaglinide together with gemfibrozil (Lopid) or NPH insulin (such as isophane insulin).
If you need to have any type of x-ray or CT scan using a dye that is injected into your veins, you will need to temporarily stop taking metformin and repaglinide.
Some people develop lactic acidosis while taking metformin. Early symptoms may get worse over time and this condition can be fatal. Get emergency medical help if you have even mild symptoms such as: muscle pain or weakness, numb or cold feeling in your arms and legs, trouble breathing, stomach pain, nausea with vomiting, slow or uneven heart rate, dizziness, or feeling very weak or tired.
Take care not to let your blood sugar get too low. Low blood sugar (hypoglycemia) can occur if you skip a meal, exercise too long, drink alcohol, or are under stress. Symptoms include headache, hunger, weakness, sweating, tremors, irritability, or trouble concentrating. Carry hard candy or glucose tablets with you in case you have low blood sugar. Other sugar sources include orange juice and milk. Be sure your family and close friends know how to help you in an emergency.
