Vial and syringe

What do GLP-1 vials look like?

Zepbound is supplied as a single-dose pen and a single-dose vial at strengths of 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg and 15 mg, each per 0.5 mL [1]. It is also supplied in a multi-dose vial holding four 0.6 mL doses per 2.4 mL vial, in concentrations from 4.17 mg/mL up to 25 mg/mL [1]. Mounjaro is supplied the same way, as 2.5 mg through 15 mg per 0.5 mL in a single-dose pen or single-dose vial [2]. A vial is drawn up with a separate syringe, unlike a pen injector, which delivers a dose without a separate draw-up step.

Does insurance treat the vial the same as the pen?

Not always. The Medicare GLP-1 Bridge program includes only the Zepbound KwikPen formulation; the single-dose vial and single-dose pen formulations are not available through that program [3]. A patient using the Medicare GLP-1 Bridge for Zepbound needs the KwikPen specifically, not a vial-and-syringe presentation, to access that coverage [3].
