Why do vial prices differ for the same drug strength?

Even when the dose (100 mg) is the same, the final price can change due to differences in:
- geography and currency,
- billing unit used (vial size vs. “per mg”),
- discounts and rebates negotiated by insurers or health systems,
- whether the listed figure is wholesale acquisition cost (WAC), list price, or another benchmark.

If you tell me your country (and whether you need list/WAC vs. an out-of-pocket estimate), I can help interpret what the figure on the page likely represents.

If you’re comparing costs, what’s the usual way to estimate total treatment cost?

Clinicians dose trastuzumab deruxtecan by patient weight and prescribed cycle schedule, then converts that into the number of vials needed per infusion. For cost comparisons, people often multiply:
- number of 100 mg vials required per dose
by
- the per‑vial price shown on the pricing source.

If you share the dosing regimen you’re using (mg per infusion and cycle frequency), I can help you translate the 100 mg vial price into a per‑cycle and per‑month estimate.
