How quickly does metformin work after taking dosage in morning?

A doctor has provided 1 answer

Quick. peaks in 3 hr: Food can slow down absorption and cause incomplete absorption. The mean time to peak levels after an 850 mg tablet (not XR) is about 3.3 hours +/- 1 hour http://www.drugs.com/pro/glucophage.html
