Ethanol + Glipizide-metformin

MediHelp rates the interaction as major. Ethanol and Glipizide-metformin can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for. Alcohol, especially in binge or heavy use, impairs hepatic lactate clearance and may potentiate metformin-associated lactic acidosis. It also unpredictably alters glucose control and raises the risk of hypoglycemia with glipizide, and a disulfiram-like reaction is rarely reported with sulfonylureas.

MediHelp rates it major, on a four-level scale (minor, moderate, major, contraindicated) based on published labels and references. What to do, in brief: Advise patients to avoid excessive or binge drinking and to take alcohol only in moderation with food. Educate on hypoglycemia symptoms and consider stopping metformin in patients with chronic alcohol misuse.

MediHelp also lists interactions of Glipizide-metformin with, for example, Contrast media, Diatrizoate meglumine / diatrizoate, Diatrizoate. The full list is on the Glipizide-metformin page.
