How to Save Money on Lubiprostone in 2026: Coupons, Discounts, and Patient Assistance

If you've ever looked at the price tag for Amitiza without insurance, you know the sticker shock is real. Brand-name Amitiza can cost $400–$530 per month for a 30-day supply of 24 mcg capsules. Even with insurance, copays can be steep. The good news is that in 2026, there are more ways than ever to bring that cost down — from generic Lubiprostone to pharmacy discount cards to patient assistance programs. Here is everything you need to know.

What Does Lubiprostone Cost in 2026?

Here's a breakdown of what you can expect to pay out of pocket in 2026 without insurance or discount programs:

• Brand Amitiza 24 mcg (60 capsules, 30-day supply): $400–$530 at retail
• Brand Amitiza 8 mcg (60 capsules, 30-day supply): $400–$530 at retail
• Generic Lubiprostone 24 mcg (60 capsules, 30-day supply): $60–$150 at retail; as low as $33–$50 with discount cards

The single biggest money-saving step most patients can take is switching to generic Lubiprostone — if they haven't already.

Step 1: Switch to Generic Lubiprostone

Generic Lubiprostone became available after Amitiza's patents expired in 2024–2025. It contains the same active ingredient at the same dose and is FDA-approved as therapeutically equivalent to brand Amitiza. Switching to generic can reduce your monthly cost by up to 85% — from as much as $530 to as low as $33 with a discount card. Ask your doctor or pharmacist if you can switch.

Step 2: Use a Pharmacy Discount Card

Pharmacy discount cards are free to use and can dramatically reduce the price of generic Lubiprostone — often below your insurance copay. The best options:

• GoodRx: Generic Lubiprostone as low as $33 per 60 capsules (30-day supply) at participating pharmacies. GoodRx coupons are available at goodrx.com — no membership required for basic coupons.
• SingleCare: Generic Amitiza available for approximately $36 per 60 capsules at participating pharmacies. Compare with GoodRx — prices can vary by $20 or more between services.
• RxSaver: Another discount card comparison platform worth checking. Prices can vary by pharmacy location.

Important: Discount cards cannot be used at the same time as insurance. When you use a discount card, you're paying out of pocket. If your insurance copay is lower than the discount card price, use insurance. If the discount card is lower, use that instead.

Step 3: Patient Assistance Programs

If you're uninsured, underinsured, or facing financial hardship, patient assistance programs (PAPs) can provide Lubiprostone at little or no cost. Key programs to know about:

• Mallinckrodt Patient Assistance Program: Mallinckrodt, which owns Amitiza, offers a patient assistance program where eligible uninsured patients may receive their medication at no cost. Contact your doctor's office or Mallinckrodt directly to apply.
• Takeda Patient Assistance Program: Takeda (former US marketer of Amitiza) also offers a patient assistance program. Check eligibility requirements at Takeda's website.
• NeedyMeds.org: A nonprofit database of all patient assistance programs. Search for Lubiprostone or Amitiza to find all available programs in one place.
• RxAssist.org: Another comprehensive PAP database maintained by a nonprofit organization.

Step 4: Check Your Insurance Coverage

Lubiprostone is covered by most Medicare and insurance plans, though often at Tier 3 on Medicare Part D formularies. Your specific copay depends on your plan. To maximize your savings:

• Call your insurance to ask about Tier placement and your specific copay for generic Lubiprostone
• Ask your doctor to submit a prior authorization if required — this is typically needed for coverage approval
• Consider using your plan's mail-order pharmacy for 90-day supplies, which often come with a lower per-pill cost

Step 5: Ask About a 90-Day Supply

Whether you're using insurance, a discount card, or paying cash, filling a 90-day supply is typically cheaper per capsule than filling 30 days at a time. Ask your doctor to prescribe a 90-day supply if clinically appropriate, and check if your pharmacy offers a discount for larger quantities.
