Metformin Prescription Information

Metformin is a drug prescribed to control blood sugar levels in people with type 2 diabetes. It is available in generic form and under brands such as Fortamet and Glucophage. Metformin decreases sugar production and absorption in the body. It does not provide insulin but helps the body respond better to its own insulin.

Dosages

• Metformin is available in tablets of several different doses. Patients take standard tablets two or three times daily or an extended-release tablet once a day. Starting dose is usually 500 mg twice a day of the standard type or 500mg or 750mg once a day of the extended-release version.

Dosage Increase

• Physicians may increase the prescription dosage if necessary up to a maximum of 2000 mg or 2550 mg, depending on the type and brand.

Extended-Release Considerations

• Patients should not chew, crush or break an extended-release tablet, because this may cause too much medication to be released at once.

Avoiding Gastrointestinal Problems

• People should take metformin with food to reduce the possibility of nausea or diarrhea, which are common side effects, especially during the first few weeks.

Other Side Effects

• Other side effects associated with metformin include gas, bloating and loss of appetite. Reducing the dosage is a consideration if any side effects make the patient consider stopping the drug.
