What is different for seniors?

Mounjaro: what the label says about older adults
What changesWhat the label says
Concomitant Use of Insulin Secretagogues or Insulin: HypoglycemiaCombining it with insulin or a sulfonylurea makes low blood sugar more likely, so those doses may need to be lowered.
Acute Kidney Injury Due to Volume DepletionFluid loss from vomiting or diarrhea may lead to kidney injury. Drink fluids and report heavy fluid loss.
Taken with insulin or sulfonylureasUsing it with insulin or a sulfonylurea raises the chance of low blood sugar. Examples of sulfonylureas include glipizide and glimepiride.
Taken with warfarin and narrow-range drugsSome medicines, such as warfarin, need closer monitoring when small changes in their level matter.

Coverage for seniors

Medicare Part D may 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 cover a GLP-1 used only for weight loss.

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