Rituximab (brand names: MabThera®, Rituxan®, Truxima®, etc.) is one of the most expensive biologics on the market, and the yearly cost can vary widely depending on the indication, dose, infusion schedule, and whether a biosimilar is used.
Below is a quick snapshot of what patients and payers might expect in the United States (prices are approximate and can shift with market changes, discounts, and insurance negotiations).
| Factor | Typical Scenario | Estimated Cost per Year |
|------------|----------------------|-----------------------------|
| Drug itself | 1 g IV on day 1 & day 15, then 1 g monthly (common for rheumatoid arthritis or low‑grade lymphoma) | $70,000–$90,000 |
| High‑dose schedule | 375 mg/m² weekly × 4 weeks, then 100 mg/m² monthly (often used for non‑Hodgkin lymphoma) | $80,000–$120,000 |
| Biosimilar (e.g., Truxima®) | Same dosing as above | $45,000–$70,000 (10‑20 % savings) |
| Short‑term use | 2–3 infusions only (e.g., a single course for a flare) | $20,000–$30,000 |
| Cost per vial | 500 mg vial (generic pricing varies) | $3,500–$4,500 (so 2–3 vials ≈ $7,000–$13,500 per infusion) |
What drives the cost?
1. Dosage & body surface area (BSA): Rituximab dosing is weight‑based (375 mg/m²). A 70 kg patient (~1.9 m²) would receive ~700 mg per infusion, roughly 1.4 vials.
2. Treatment duration: Chronic conditions (e.g., RA) often require yearly infusions, while some cancers need intense, short‑term courses.
3. Biosimilar vs. originator: Biosimilars are typically 10–20 % cheaper, but many insurers still list the originator first.
4. Insurance & copay tiers: Out‑of‑pocket costs can range from a few hundred dollars to several thousand, depending on your formulary and deductible.
5. Infusion center fees: The drug is usually infused in a clinical setting, adding $200–$500 per visit.
Quick tips for patients
- Ask your prescriber about biosimilar options – they can often be switched without loss of efficacy.
- Check your insurer’s formulary – some plans have “preferred” brands with lower copays.
- Explore patient assistance programs – many manufacturers offer co‑insurance help or patient support funds.
- Track your total cost – beyond the drug, include infusion fees, lab monitoring, and any additional medications.
