How much does daptomycin cost per day?
Daptomycin pricing varies a lot by country, dose (mg/kg), treatment duration, and whether the pharmacy uses the brand product or a generic version (plus payer discounts and patient assistance). To estimate a per-day cost, you need (1) the vial strength(s) and (2) the patient’s prescribed daily dose in mg.
If you want, share the prescribed dose (e.g., 6 mg/kg daily for a specific weight) and your country (or whether you’re using US Medicare/Commercial pricing), and I can help convert a quoted price into an approximate “cost per day” and “cost per course” number.
What dose assumptions drive the per-day cost?
Daptomycin is typically prescribed once daily by weight, commonly as a fixed mg/kg regimen. That means daily cost scales with body weight and selected mg/kg. Small changes in dose can noticeably change the number of vials needed each day, which then changes the daily cost.
To calculate “cost per day” from any list price:
1) Convert dose to total mg/day (mg/kg × weight).
2) Determine how many vials/grams are used to cover that daily total.
3) Multiply by the per-vial price and adjust for partial vial use (if your pricing source provides vial-level costs).

Why “per day” can differ even with the same dose
Even with the same mg/kg and weight, daily cost may differ due to:
- vial sizes available and how the dispensing pharmacy bills partial vial usage,
- negotiated payer pricing vs list price,
- whether the course is inpatient vs outpatient,
- switching to an alternative formulation/brand or generic,
- insurance coverage, deductible/coinsurance, and patient assistance.
Tell me your numbers and I’ll compute a daily figure
Reply with:
- country (and insurance type if US),
- prescribed regimen (mg/kg) and patient weight (kg),
- whether you’re looking for brand vs generic (if known),
- the price you’re using (or I can use a referenced price you provide).
Then I’ll calculate an estimated daptomycin cost per day and per typical treatment course.
