Long-term use of metformin for diabetes generally does not cause significant harm to the body. Metformin helps control blood glucose levels and prevent diabetic complications. If a patient has good tolerance, adverse reactions are typically uncommon. Patients should follow their physician’s instructions—starting with a low dose and taking metformin after meals. Regular follow-up examinations are also recommended.
