Glutamine (Endari) can cost over $3,000 a month without help. Learn about copay programs, GoodRx coupons, and patient assistance options that can dramatically reduce your cost.
Glutamine (Endari) for sickle cell disease isn't cheap. The average retail price for a 30-day supply is more than $3,200 — and without insurance or financial assistance, that cost is simply out of reach for most patients. Even with insurance, the specialty tier placement, prior authorization requirements, and high copays can create serious financial strain.
The good news: several programs exist specifically to help patients afford Glutamine. Here's a complete breakdown of every savings option available in 2026.
How Much Does Glutamine (Endari) Cost Without Insurance?
Without insurance or a discount program, Glutamine is extremely expensive:
Average retail price: ~$3,200–$3,471 for 180 packets (30-day supply)
With GoodRx coupon: As low as ~$1,013 for a 30-day supply — a 68–71% reduction
60-day supply cash price: Approximately $2,773 at cash pricing
These prices apply to both brand-name Endari and the FDA-approved generic L-glutamine oral powder (available since July 2024). Prices vary by pharmacy and location.
Option 1: Emmaus Copay Assistance Program (Commercially Insured Patients)
If you have commercial or private insurance, this is likely your best option. The Endari Commercial Copay Assistance Program is run by Emmaus Medical and significantly reduces your monthly out-of-pocket costs:
You pay: as little as $10 per monthly prescription (the first $10 of your copay)
Emmaus pays: the remainder of your copay, up to an annual limit
Who qualifies: commercially insured patients in the U.S., Puerto Rico, or U.S. territories; you must be 18+ to enroll for yourself or a minor
Who does NOT qualify: patients with Medicare, Medicaid, or other federally funded insurance programs
How to enroll: Visit endarirx.com/copay-assistance, complete the Patient Financial Assistance Application, or call 855-723-5646.
Option 2: Endari Support Program (Uninsured or Underinsured Patients)
If you don't have insurance or can't afford your prescription, the Endari Support Program may provide Glutamine at minimal or no cost. Emmaus launched this program in December 2020 in partnership with TheraCom Specialty Pharmacy (part of AmerisourceBergen).
Intended for: patients unable to afford the cost of treatment and lacking adequate insurance coverage
Cost: minimal or no-cost medication, depending on eligibility
How to apply: Call 1-855-723-5646 or visit endarirx.com/esp to complete the online application
Option 3: GoodRx Coupon
GoodRx offers discount coupons for L-glutamine that can reduce the retail price by up to 71%. This option is available to anyone — regardless of insurance status — and works at participating specialty pharmacies.
Price with GoodRx: As low as ~$1,013 for a 30-day supply (180 packets of 5g)
How to use it: Get a free GoodRx coupon at goodrx.com/endari, then show it to the pharmacist when picking up your prescription
Important: You cannot use a GoodRx coupon together with your insurance. Use whichever gives you the lower price.
Option 4: Other Discount Cards (SingleCare, WellRx, RxSaver)
In addition to GoodRx, several other pharmacy discount programs may offer competitive pricing on L-glutamine at specialty pharmacies near you. It's worth comparing prices on:
SingleCare (singlecare.com)
WellRx (wellrx.com)
RxSaver by RetailMeNot (rxsaver.com)
Option 5: Medicare Part D and the $2,000 Cap
For Medicare Part D beneficiaries, Glutamine is typically placed on Tier 5 (specialty tier). This can mean high initial costs. However, starting in 2025, Medicare Part D has an annual $2,000 out-of-pocket cap. Once you reach this cap, your plan covers 100% of your covered medications for the rest of the year — which can be a major benefit for sickle cell patients taking multiple specialty drugs.
Option 6: SCD-Specific Financial Assistance Programs
Several non-profit organizations provide financial assistance to help cover medication costs for people with sickle cell disease:
HealthWell Foundation: Covers insurance premiums and copays for SCD patients (check if currently accepting applications)
Patient Advocate Foundation: Health equity fund for SCD patients in high-vulnerability areas
Sickle Cell Disease Association of America: Resources and referrals for financial assistance; visit sicklecelldisease.org
Quick Summary: Glutamine Savings Options in 2026
Commercially insured: Emmaus copay program → as low as $10/month
Uninsured/underinsured: Endari Support Program → minimal or no cost
Medicare Part D: $2,000 annual OOP cap as of 2025; cannot combine with manufacturer copay cards

Frequently Asked Questions
With commercial insurance, your cost depends on your plan's tier placement and prior authorization. Most plans require prior auth and place Glutamine on a specialty tier. With the Emmaus copay assistance program, commercially insured patients can pay as little as $10/month. Medicare Part D patients are now protected by a $2,000 annual OOP cap (effective 2025).
If you have no insurance, the Endari Support Program (for patients who can't afford the medication) may provide it at minimal or no cost. Call 1-855-723-5646 to check eligibility. Alternatively, a GoodRx coupon can reduce the retail price from ~$3,200 to as low as ~$1,013 per 30-day supply at participating specialty pharmacies.
Yes, but you cannot use both simultaneously. If your GoodRx price is lower than your insurance copay, you can choose to use the GoodRx coupon instead. Present it at the specialty pharmacy checkout in place of your insurance card. Compare both prices before filling.
Medicare Part D covers Glutamine, but it's typically on Tier 5 (specialty tier), which means higher cost sharing. Most Medicare plans require prior authorization and quantity limits. As of 2025, Part D has a $2,000 annual OOP cap, which significantly limits maximum out-of-pocket spending. Medicare patients cannot use manufacturer copay assistance programs.
The generic L-glutamine oral powder by ANI Pharmaceuticals (FDA-approved July 2024) may be available at a lower price than brand-name Endari at some specialty pharmacies. However, as a specialty medication, prices remain high without assistance. Ask your specialty pharmacist to check both brand and generic prices before filling.
