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

Mirabegron XR (brand name: Myrbetriq) is one of the most effective medications for overactive bladder — but it comes with a price tag that catches many patients off guard. Without insurance or a savings program, brand Myrbetriq retails for $450 to $625 per month. Generic mirabegron, when available, costs $450 to $663 at retail but can be significantly reduced with coupons. The good news: there are multiple legitimate ways to cut this cost substantially. Here is the complete savings playbook for 2026.

What Does Mirabegron XR Actually Cost in 2026?

Brand Myrbetriq 25 mg (30 tablets, retail): Approximately $458

Brand Myrbetriq 50 mg (30 tablets, retail): Approximately $625

Generic mirabegron ER 50 mg (30 tablets, retail): Approximately $450-$663

With insurance (typical copay): $0-$100 per month depending on plan tier and deductible status

Medicare Part D average: Approximately $180 per claim

Option 1: GoodRx — The Fastest Way to Lower Generic Costs

GoodRx is a free-to-use coupon service that negotiates discounted pricing at thousands of pharmacies. When generic mirabegron is in stock at a pharmacy near you, a GoodRx coupon can bring the cost down to approximately $121 for a 30-day supply — that's 73% off the average retail price. GoodRx works even if you have insurance, and in many cases, the GoodRx cash price is lower than your insurance copay.

How to use it: Go to GoodRx.com, type "mirabegron," enter your zip code, and compare prices at nearby pharmacies. Show the coupon at the pharmacy counter — either on your phone or printed.

Important note: Due to the 2025 patent litigation that disrupted generic mirabegron supply, not all pharmacies will have generic in stock. If GoodRx shows it available at a nearby pharmacy, call ahead to confirm before making the trip.

Option 2: SingleCare — An Alternative Coupon Service

SingleCare is another pharmacy discount program worth checking. Generic mirabegron ER with a SingleCare coupon costs approximately $189 per 30 tablets at select pharmacies. Prices vary by pharmacy location, so compare both GoodRx and SingleCare to find the best price in your area.

Option 3: The Astellas Momentum Savings Card (Brand Myrbetriq)

If you have commercial (employer-provided or private) health insurance and are taking brand-name Myrbetriq, the Astellas Momentum Savings Card can significantly reduce your out-of-pocket costs. This copay assistance card is available through Astellas's patient support program and is offered through the Myrbetriq official website.

This card is not available to Medicare, Medicaid, or other government insurance patients, as these programs prohibit manufacturer copay assistance. It is best suited for commercially insured patients whose plans cover Myrbetriq but have a high copay.

Patients who are uninsured or underinsured and meet income eligibility requirements may qualify for the Astellas Patient Assistance Program (PAP), which provides Myrbetriq at reduced or no cost. Eligibility is based on income relative to the federal poverty level. Your prescriber or their office can help complete the application.

To apply, ask your doctor's office about the Astellas patient support program or visit the manufacturer's official website for current enrollment information.

Option 5: Cost Plus Drugs (Mark Cuban's Pharmacy)

Mark Cuban's Cost Plus Drugs (costplusdrugs.com) offers generic medications at transparent, low prices. Check their site to see if generic mirabegron is available through their formulary. If it is, this can be one of the lowest cost-per-tablet options.

Option 6: Medicare Extra Help (Low-Income Subsidy)

If you are on Medicare Part D and have limited income and resources, you may qualify for Extra Help (also called Low-Income Subsidy or LIS). This federal program reduces premiums, deductibles, and copays for Medicare prescription drug coverage. Contact the Social Security Administration or your local Medicare office to check eligibility.

Option 7: Switch to Generic and Ask Your Pharmacy to Order It

If your doctor prescribed brand Myrbetriq, ask whether switching to generic mirabegron extended-release is appropriate for you. They contain the same active ingredient at the same dose. Generic is often covered at a lower insurance tier (Tier 1 vs. Tier 2-3 for brand), meaning a lower copay. When generic is in stock, it can be 80-85% cheaper than brand.

Savings Summary: Quick Reference

Generic + GoodRx: ~$121/month (when in stock)

Generic + SingleCare: ~$189/month (when in stock)

Brand Myrbetriq + Astellas Savings Card: Reduced copay for commercially insured patients

Uninsured/underinsured: Apply for Astellas Patient Assistance Program

Medicare with low income: Apply for Medicare Extra Help (LIS)
