Taken with insulin or sulfonylureas	Combining this medicine with insulin or a sulfonylurea, including glipizide or glimepiride, increases the chance of low blood sugar. Your doctor may reduce the doses of those medicines.	All of them

Medicare Part D can cover these medicines when they are prescribed for diabetes or cardiovascular disease.

Part D plans may cover a GLP-1 for type 2 diabetes, moderate to severe sleep apnea or fatty liver disease.

Medicare Part D does not pay for a GLP-1 used only for weight loss.

Under the Medicare GLP-1 Bridge, Zepbound is listed at $50 per month for people who meet its rules.

Where Medicaid covers weight-loss GLP-1s, prior authorization is standard.
