Can I take metformin with GLP-1 medications?

Yes, metformin and GLP-1 medications are commonly prescribed together and have complementary mechanisms. Metformin improves insulin sensitivity and reduces hepatic glucose production, while GLP-1 agonists enhance insulin secretion, suppress glucagon, and reduce appetite. Many type 2 diabetes patients take both medications simultaneously. For weight loss, some providers prescribe metformin alongside GLP-1s to enhance insulin sensitivity and potentially reduce weight regain risk. There are no significant drug interactions between metformin and GLP-1 medications. Both can cause gastrointestinal side effects, so starting them together may increase nausea initially.
