Rosiglitazone and metformin combination is used to treat a type of diabetes mellitus called type 2 diabetes. It is used together with a proper diet and exercise to help control blood sugar levels.

Rosiglitazone helps your body use insulin better. Metformin reduces the absorption of sugar from the stomach, reduces the release of stored sugar from the liver, and helps your body use sugar better.

If you are rapidly gaining weight or having trouble breathing, chest pain or discomfort, extreme tiredness or weakness, irregular breathing, irregular heartbeat, or excessive swelling of the hands, wrist, ankles, or feet, check with your doctor right away. These may be symptoms of a heart problem or edema (fluid retention).

Let your doctor or dentist know you are taking this medicine. Your doctor may advise you to stop taking this medicine before you have major surgery or diagnostic tests, especially tests that use a contrast dye.

Under certain conditions, too much metformin can cause a serious condition called lactic acidosis. The symptoms of lactic acidosis are severe and appear quickly. Lactic acidosis usually occurs when other serious health problems are present, such as a heart attack or kidney failure. The symptoms of lactic acidosis include: abdominal or stomach discomfort, decreased appetite, diarrhea, fast or shallow breathing, a general feeling of discomfort, muscle pain or cramping, and unusual sleepiness, tiredness, or weakness. If you have more than one of these symptoms together, you should get immediate emergency medical help.

• Counseling—Other family members need to learn how to prevent side effects or help with side effects if they occur. Also, patients with diabetes may need special counseling about diabetes medicine dosing changes that might occur because of lifestyle changes, such as changes in exercise and diet. Furthermore, counseling on contraception and pregnancy may be needed because of the problems that can occur in patients with diabetes during pregnancy.
• Travel—Keep a recent prescription and your medical history with you. Be prepared for an emergency as you would normally. Make allowances for changing time zones and keep your meal times as close as possible to your usual meal times.
• In case of emergency—There may be a time when you need emergency help for a problem caused by your diabetes. You need to be prepared for these emergencies. It is a good idea to wear a medical identification (ID) bracelet or neck chain at all times. Also, carry an ID card in your wallet or purse that says that you have diabetes and a list of all of your medicines.
• Symptoms of fluid retention—Know what to do if you start to retain fluid. Fluid retention may worsen or lead to heart problems.

This medicine may cause hypoglycemia (low blood sugar). This is more common when this medicine is taken together with certain medicines.
