No authorized generic: There isn’t one.

Regular generic: Sold only in a different form, strength or formula. Switching to one would need a new prescription, so ask your prescriber whether it could work for you.

Prices are the average U.S. drugstores pay (source: Medicaid, September 23, 2026). What you pay depends on your plan or the pharmacy.

Co-pay cards can’t be used with Medicare (including Medicare Advantage), Medicaid, TRICARE or VA.

In the maker’s words

“With MOTPOLY XR Copay Savings, pay as little as $10 per month on your MOTPOLY XR prescriptions…”

From the maker’s offer on motpolyxr.com, checked September 25, 2026. What you pay depends on your plan. Co-pay cards can’t be used with Medicare (including Medicare Advantage), Medicaid, TRICARE or VA.

Before you use a discount card

Discount cards like GoodRx take money off the pharmacy’s cash price. For a brand-name drug, that price is often still high. With commercial insurance, Motpoly XR’s own card may bring it to as little as $10 a month.

Look up the discount-card price, then compare it with this estimate. You can use a maker’s card or a discount card, but usually not both on the same fill.

What pharmacies pay

The average U.S. drugstores pay for each strength (source: Medicaid, September 23, 2026). What you pay depends on your plan or the pharmacy.

Good to know

There’s no authorized generic of Motpoly XR.
“Commercial insurance” means a plan from a job, from the marketplace, or one you buy yourself. A retiree plan that’s part of Medicare counts as Medicare. Co-pay cards can’t be used with Medicare (including Medicare Advantage), Medicaid, TRICARE or VA.
Most cards need a sign-up on the maker’s site, and many work only if your plan covers the drug. Then give the card’s details to your pharmacy.
Don’t stop or change a medicine without talking to your pharmacist or prescriber.
