This is a prescription medicine. Tell your doctor about kidney or liver problems. Metformin is not suitable in significant kidney impairment. Stop and seek urgent care for signs of lactic acidosis (rare): rapid breathing, severe weakness, muscle pain or feeling very cold. Metformin should be paused around contrast-dye scans or serious illness. On its own it rarely causes low blood sugar, but the risk rises with insulin or a sulfonylurea. Stop and seek help for severe, persistent stomach pain (possible pancreatitis). Limit alcohol. Avoid in pregnancy/breastfeeding unless advised. Store in a cool, dry place.
