Amifampridine (Fampyra) is a specialty medication approved for treating Lambert‑Eaton Myasthenic Syndrome (LEMS). Because it’s a rare‑disease therapy, the cost can be substantial, but the exact amount you’ll pay depends on a few key factors:
| Factor | What it means | Typical impact on your bill |
|--------|---------------|-----------------------------|
| Manufacturer’s list price | The “sticker price” set by Pfizer (the brand name Fampyra) | Roughly $30,000 – $40,000 per year (based on public estimates and news reports). |
| Insurance coverage / formulary tier | Whether your plan lists Amifampridine as a covered drug, and at what tier (e.g., tier 1 vs. specialty). | If it’s covered, you’ll pay a copay or coinsurance (often 20‑30 % of the list price). If not covered, you’ll be responsible for the full list price or a negotiated discount. |
| Manufacturer discount / pharmacy benefit manager (PBM) negotiation | Many plans negotiate rebates or discounts with the manufacturer. | The discount can reduce the net price by 20‑40 % for insured patients, but the exact figure depends on your contract. |
| Financial assistance / patient assistance program | Pfizer’s “Fampyra Assistance Program” is available for patients who meet income and insurance eligibility criteria. | Can cover 50‑100 % of the drug cost; the application process is usually straightforward online or by phone. |
| State or federal insurance programs | Medicare, Medicaid, and some state health plans may have specific rules for rare‑disease drugs. | Some programs negotiate special rebates; others may require prior authorization or a “specialty drug” designation. |
| Prescription location | Where you fill the medication (e.g., specialty pharmacy, retail pharmacy). | Specialty pharmacies often have dedicated assistance staff and may help navigate insurance and financial aid. |
Quick Take‑away
- List price: ~$30‑40 k per year.
- With insurance: Expect a copay/coinsurance of 20‑30 % of that amount if the drug is covered and you’re on the right formulary tier.
- Without insurance: The full list price is payable unless you qualify for the patient assistance program.
- Assistance available: Pfizer offers a patient assistance program; many insurers also provide negotiated rebates that lower your out‑of‑pocket cost.

How to find out what you’ll pay
1. Ask your prescriber for your insurer’s formulary status (they usually can pull this quickly).
2. Call your insurance (or check the online member portal) to confirm:
- Whether Amifampridine is on formulary.
- What copay/coinsurance applies.
- Whether prior authorization or a prior step‑therapy requirement is needed.
3. Contact the manufacturer’s assistance program if the drug is not covered or if you’re on a high‑cost plan. You can apply online at:
