    The pill you have is possibly Metformin HCl Tab 500 MG
    Manufacturer: CARACO
    Imprint Code 397
    Color white
    Shape round

    You will find a description (but no image) in the prescribing information at

    Metformin is used to regulate blood glucose (sugar) levels. Metformin works in three ways: first, it reduces the amount of glucose produced by your liver; second, it reduces the amount of glucose absorbed from food through your stomach; and third, it makes the insulin that your body produces work better to reduce the amount of glucose already in your blood.
    Metformin is used to treat non-insulin-dependent diabetes mellitus (NIDDM or Type II diabetes). Metformin may be used alone or together with insulin or other diabetes medicines.
