Important Warnings

Not for type 1 diabetes or diabetic ketoacidosis. Metformin can rarely cause lactic acidosis—risk increases with kidney disease, severe dehydration, sepsis, heavy alcohol use, liver disease, or hypoxia/heart failure; assess renal function before and during therapy. Temporarily stop metformin before iodinated contrast procedures and major surgery as advised. Pancreatitis and severe joint pain have been reported with DPP-4 inhibitors—seek medical help for severe abdominal pain. Monitor blood glucose; risk of hypoglycaemia increases when combined with insulin or sulfonylureas.

Teneway M 500MG Tab may interact with the following:

Alcohol (increases lactic acidosis risk)

cationic drugs affecting renal tubular secretion (e.g.
