Rosiglitazone/Metformin

Generic Name: Rosiglitazone/Metformin (ROE-zi-GLI-ta-zone/met-FOR-min)Brand Name: Avandamet

Rosiglitazone/Metformin 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 who drink alcohol. Lab tests, including kidney function, may be performed while you take Rosiglitazone/Metformin .

Do not begin to take Rosiglitazone/Metformin if you are more 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 or low blood oxygen levels, or are dehydrated. Tell your doctor you take Rosiglitazone/Metformin 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 lightheadedness; 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.

Thiazolidinedione antidiabetics such as Rosiglitazone/Metformin may cause or worsen heart failure in some patients. They may also increase the risk of certain other severe heart problems (eg, chest pain, heart attack). Tell your doctor if you have a history of heart failure. Rosiglitazone/Metformin should not be used to treat patients with moderate to severe heart failure. You will be monitored for signs of heart failure when you start Rosiglitazone/Metformin and when your dose increases. Contact your doctor at once if you develop swelling of the hands, ankles, or feet; shortness of breath; sudden unexplained weight gain; chest pain; numbness of an arm or leg; sudden severe headache, dizziness, or vomiting; sudden vision changes; or fainting. Your doctor may need to stop your medicine or change your dose.

Rosiglitazone/Metformin is used for:

Treating type 2 diabetes. It is used along with diet and exercise. It may be used alone or with other antidiabetic medicines.

Rosiglitazone/Metformin is a thiazolidinedione and biguanide antidiabetic combination. It works by decreasing the amount of sugar that the liver produces and the intestines absorb. It also helps to make your body more sensitive to the insulin that you naturally produce.

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.

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.
  • An increased incidence of bone fracture has been reported in women who take Rosiglitazone/Metformin . Tell your doctor if you have a history of bone fracture, low calcium intake, or weak bones (eg, osteoporosis). Tell your doctor right away if you experience any unusual bone pain.
  • Lab tests, including fasting blood sugar, hemoglobin A1c, eye examinations, and liver function, may be performed while you use Rosiglitazone/Metformin . These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
  • Use Rosiglitazone/Metformin 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 the elderly.
