Your current medication is a combination of three active generic ingredients: Glimepiride (1 mg), Metformin (500 mg), and Voglibose (0.2 mg). A suitable substitute would be any medication containing this exact same generic formulation in the same strengths. Since you have an underlying heart condition, it is highly recommended not to switch your medicine without consulting your doctor first. Slight variations in generic absorption can affect your blood sugar and heart health. Please consult your cardiologist or diabetologist so they can safely transition you to an equivalent alternative with this exact generic composition.
