The dosing of Glucophage® (metformin) or Glucophage XR® (metformin ER) your healthcare provider prescribes will vary depending on a number of factors, including:
* How well your diabetes is controlled
* Other medical conditions you may have
* Other medications you may currently be taking.
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you do to so.
For regular (not long-acting) Glucophage, the dosing varies with age, as follows:

* Age 10 to 16 -- The starting dose is Glucophage 500 mg twice daily. The maximum dose for people in this age group is Glucophage 2000 mg total per day, divided into two or three doses.
* Age 17 and over -- The starting dose is Glucophage 500 mg twice daily or 850 mg once daily. The maximum dose for people in this age group is 2550 mg total daily, divided into two or three doses per day.

For the long-acting form, Glucophage XR, the starting dose is Glucophage XR 500 mg once daily, and the maximum dose is Glucophage XR 2550 mg once daily.
