How Riomet OD 500 mg Tablet works
Metformin lowers blood sugar by reducing the amount of glucose your liver releases and by helping your muscles respond better to your own insulin. It does not force your pancreas to make more insulin, which is why it rarely causes low blood sugar on its own.

Swallow the tablet whole with a glass of water. Do not chew, crush or break it unless your doctor has told you to. Take it with or just after food. Taking it at about the same time each day helps you remember. Follow the dose and the duration written on your prescription.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
