When is the best time to take metformin extended-release tablets?

Metformin is a commonly used oral antidiabetic medication, especially suitable for patients with type 2 diabetes. The design of the extended-release tablets aims to prolong the drug's release time in the body, thereby maintaining stable blood glucose levels. Generally, the administration of metformin extended-release tablets is as follows: 1. Timing of administration: It is generally recommended to take the medication during or after meals. This helps reduce the likelihood of gastrointestinal discomfort, as food can alleviate the drug's irritation to the stomach. 2. Dosage frequency: If the physician prescribes twice daily, the doses are usually taken with breakfast and dinner, respectively. If once daily is prescribed, it is typically taken with dinner, as the drug's effect can then cover the period of nocturnal blood glucose elevation. Note that if any discomfort or questions arise, prompt consultation with a physician is advised.
