Metformin is a commonly used antidiabetic medication, and the only oral medication approved for children and adolescents under 18 years old. Though reasonably effective, gastro-intestinal side effects are common (80% at initiation, and 10-30% after long term use). Metformin dosing at clinically recommended doses will be titrated per protocol during the study.
