What differs when you have PCOS?
| What changes | What the label says |
|---|---|
| Hypoglycemia | When you use it with insulin or a sulfonylurea, low blood sugar becomes more likely, and those doses may need to be lowered. |
| Taken with birth control pills | Birth control pills may not work as well for a while. Use a method that is not oral, or add a barrier method after you start and each time the dose goes up. |

Coverage for PCOS
A GLP-1 used only for weight loss has no coverage under Medicare Part D.
According to the Medicare GLP-1 Bridge, Zepbound is priced at $50 each month for anyone who qualifies under its rules.
Wherever Medicaid offers coverage, weight-loss GLP-1s normally require prior authorization.
