How much is tremfya with insurance?

Prices for Tremfya (guselkumab) with insurance vary a lot by country, plan, and your individual cost-sharing (deductibles, copays/coinsurance, formulary tier, prior authorization, etc.). Here’s a quick rundown to help you estimate:

- How it’s given: Tremfya is a 100 mg injection given at week 0, week 4, then every 8 weeks. That’s 8 injections in a year for most people.
- With US commercial insurance: many patients pay a small out-of-pocket per month (often $0–$50) after applying the manufacturer savings program, but other plans with higher deductibles or coinsurance can cost more. Government programs (like Medicare/Medicaid) may have different coverage and typically don’t use the same savings cards.
- List price (before insurance): the sticker price for a 100 mg dose is in the thousands of dollars. Eight doses per year means the annual pre-insurance cost is typically in the tens of thousands of dollars if you’re paying full price.

To get your exact number:
- Check your insurer’s formulary and your plan’s cost-sharing for Tremfya in your online account or by calling member services.
- Ask your pharmacist or clinic to run a benefits verification to show your estimated out-of-pocket.
- See if you qualify for Lilly’s Tremfya patient savings/assistance program.
- If you’re paying cash or comparing prices, you can check cash-price estimates (or discount programs like GoodRx) as a rough reference, though that won’t reflect insurance.

If you tell me your country and whether you have commercial insurance (and, if possible, your plan name) or government coverage, I can tailor the guidance and help you estimate more precisely.
