Actoplus Met XR

Actoplus Met XR is a prescription medication used to treat type 2 diabetes.

It is a single product containing 2 medications: immediate-release pioglitazone and extended-release metformin.

Pioglitazone belongs to a group of drugs called thiazolidinediones. These work by increasing the body’s sensitivity to insulin. Metformin belongs to a group of drugs called biguanides. These work by decreasing the amount of glucose absorbed from food and decreasing the amount of glucose that is produced by the liver.

This medication comes in tablet form and is taken one or two times a day, with food.

Common side effects of Actoplus Met XR include upper respiratory tract infection, edema, diarrhea, headache, muscle pain, and weight gain.

In combination with other medications to treat diabetes, Actoplus Met XR can also cause hypoglycemia (low blood sugar), which can cause blurred vision and dizziness. Do not drive or operate heavy machinery until you know how Actoplus Met XR affects you.

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Actoplus Met XR 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.

Tell your doctor if you are breastfeeding or plan to breastfeed.

No studies of the combination of ingredients in Actoplus Met XR have been evaluated in nursing women. The individual components have been detected in human breast milk.
