Metformin 常見的副作用為腸胃道不適，如腹瀉、噁心與腹痛。這些症狀通常隨服用時間增加而改善，建議隨餐服用以減緩不適。A 是錯的，Metformin 單獨使用不易導致低血糖；C 錯，病人仍需攝取均衡碳水化合物；D 錯，此藥需規律服用以控制血糖。
Gastrointestinal disturbances such as abdominal discomfort and diarrhea are common side effects of metformin, often improving over time or with food intake. Unlike insulin or sulfonylureas, metformin alone rarely causes hypoglycemia, and it requires consistent daily dosing rather than PRN use for effective glycemic control.
