Duetact lowers blood sugar. Take Duetact with the first meal of the day.
Duetact is a prescription medication used to treat Type 2 Diabetes. It is used in combination with diet and exercise. It is available as a single product containing 2 medications—pioglitazone and glimepiride.
Pioglitazone belongs to a class of drugs called thiazolidinediones. It helps the body control blood sugar levels by making the body more sensitive to insulin. Glimepiride is in a different class of drugs called sulfonylureas. It causes the pancreas to make more insulin and helps the body to use insulin more efficiently. This helps to control blood sugar.
Duetact is available as a tablet and is taken once daily, with the first meal of the day.
Common side effects of Duetact include hypoglycemia, upper respiratory tract infection, increased weight, and lower limb swelling.
Duetact may cause low blood sugar, also known as hypoglycemia. This can reduce your ability to concentrate or react. Do not drive or operate heavy machinery until you know how Duetact affects you, or if you are having any signs or symptoms of hypoglycemia.

Duetact falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well–controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.
