The Zepbound label: points for older adults
What changes	What the label says
Acute Kidney Injury Due to Volume Depletion	Vomiting or diarrhea can cause fluid loss, which may lead to kidney injury. Drink fluids and report heavy fluid loss.
Hypoglycemia	Low blood sugar is more likely if you take it with insulin or a sulfonylurea, and you may need to lower those doses.
Taken with insulin or sulfonylureas	Using it with insulin or a sulfonylurea raises the risk of low blood sugar, so those doses may need lowering.
Taken with warfarin and narrow-range drugs	Some drugs, such as warfarin, need closer monitoring because small level changes matter.

According to the FDA labels: FDA label (DailyMed).

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 will not pay for a GLP-1 that is used only for weight loss.

The Medicare GLP-1 Bridge lists Zepbound at $50 per month for people who meet its rules.

Medicaid usually requires prior authorization when it covers weight-loss GLP-1s.
