What is the most important information I should know about glimepiride and pioglitazone (Duetact)?

Do not take glimepiride and pioglitazone for longer than recommended. Taking this medication for longer than 1 year (12 months) may increase your risk of developing bladder cancer. Talk with your doctor about your specific risk.

Before taking glimepiride and pioglitazone, tell your doctor if you have congestive heart failure or heart disease, a history of bladder cancer, a history of heart attack or stroke, liver disease, or kidney disease.

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, tremor, 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.

Certain oral diabetes medications may increase your risk of serious heart problems. However, not treating your diabetes can damage your heart and other organs. Talk to your doctor about the risks and benefits of treating your diabetes with glimepiride and pioglitazone.
