Pharmacy tech tips
- Zepbound cartons hold 4 single-dose pens, which is a 28 day supply at any strength.
- Single-dose vials for the self-pay program are billed by total mL, not by pen count.
- A titration fill that mixes strengths is still counted one weekly dose at a time.
Frequently asked questions
How do you calculate day supply for Zepbound?
Multiply the number of single-dose pens by seven. A carton of four pens dosed once weekly is a 28 day supply.
Is Zepbound a 28 or 30 day supply?
It is a 28 day supply. Four weekly doses cover four weeks, so entering 30 days can cause a refill too soon rejection on the next fill.
