What is Invanz (ertapenem) and how is “cost per dose” typically quoted?
Invanz is the brand name for ertapenem, an antibiotic given as an injection (or IV infusion) for certain serious bacterial infections. “Cost per dose” is usually calculated from (1) the vial size (commonly 1 g for adults), (2) the number of vials used per administration, and (3) the payer setting (cash price vs. commercial insurance vs. Medicaid/340B), which can change the effective price a lot.
What affects the Invanz cost per dose the most?
The main drivers are:
- Dose strength used (often 1 g per adult dose, but the exact regimen depends on indication).
- Route (IM vs IV) and whether administration requires additional supplies.
- Treatment setting and contract pricing (hospital buy price vs pharmacy cash price).
- Patient assistance programs and insurance formulary status.

If you tell me your situation, I can narrow it to a real “per dose” estimate
“Cost per dose” can be very different depending on dose and payer. If you share:
- the dose (e.g., 1 g),
- route (IV or IM),
- country (US vs another),
- and whether you want cash price, insurance copay, or hospital/wholesale-style pricing,
I can help compute a more meaningful per-dose figure using the available pricing context.
