Generic Name: metformin and repaglinide (met FOR min and re PAG li nide)
Brand Names: PrandiMet
What is PrandiMet?
PrandiMet contains a combination of metformin and repaglinide. 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.
PrandiMet is used to improve blood sugar control in adults with type 2 diabetes.
PrandiMet is not for treating type 1 diabetes.
You should not use PrandiMet if you are allergic to metformin or repaglinide, if you have severe 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 PrandiMet together with gemfibrozil 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 this medicine.
PrandiMet may cause a serious condition called lactic acidosis. 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.

How should I take PrandiMet?
Take PrandiMet exactly as prescribed by your doctor. Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not use this medicine in larger or smaller amounts or for longer than recommended.
PrandiMet is usually taken 2 or 3 times daily, within 15 minutes before eating a meal. Follow your doctor's instructions. If you skip a meal, do not take your dose of PrandiMet. Wait until your next meal.
Your blood sugar will need to be checked often, and you may need other blood tests at your doctor's office.
Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, confusion, irritability, dizziness, or feeling shaky. Always keep a source of sugar with you in case you have low blood sugar. Sugar sources include fruit juice, hard candy, crackers, raisins, and non-diet soda. Be sure your family and close friends know how to help you in an emergency.
If you have severe hypoglycemia and cannot eat or drink, use a glucagon injection. Your doctor can prescribe a glucagon emergency injection kit and tell you how to use it.
Check your blood sugar carefully during times of stress, travel, illness, surgery or medical emergency, vigorous exercise, or if you drink alcohol or skip meals. These things can affect your glucose levels and your dose needs may also change. Do not change your medication dose or schedule without your doctor's advice.
Your doctor may have you take extra vitamin B12 while you are taking PrandiMet. Take only the amount of vitamin B12 that your doctor has prescribed.
PrandiMet is only part of a complete treatment program that may also include diet, exercise, weight control, and special medical care. Follow your doctor's instructions very closely.
Store at room temperature away from moisture, heat, and light. Keep the bottle tightly closed when not in use.
