Yes — Medicare does cover Nystop in most cases, through Part D prescription drug plans or the drug coverage built into a Medicare Advantage plan. Nystop is the brand name for nystatin topical powder, a prescription antifungal, and because it requires a prescription it qualifies as a Part D drug.1CMS. Medicare Prescription Drug Benefit Manual, Chapter 6 Plans place the generic version on their formularies far more consistently than the brand, usually on the lowest cost-sharing tier.
Part D, Not Part B
Nystop is a self-applied topical powder, which puts it squarely in Part D territory. Part B covers drugs given in a clinical setting or through durable medical equipment, and nystatin products are not flagged as Part B drugs on Medicare plan formularies.2Formulary Navigator. Tufts Medicare Preferred PDP Formulary If you have Original Medicare without a Part D plan, Nystop is not covered. You would need a standalone Part D plan or a Medicare Advantage plan that includes drug coverage.
Nystatin is one of the most commonly dispensed topical antifungals under Part D. In 2021, Part D beneficiaries filled about 1.9 million nystatin prescriptions, roughly 29 percent of all topical antifungal fills that year.3CDC.

Brand-Name Nystop vs. Generic Nystatin
Formularies vary, but the pattern is consistent: generic nystatin powder is covered by most Medicare plans, usually at Tier 1 with the lowest copay.5GoodRx. Nystop Medicare Coverage The brand-name Nystop may be on your plan’s drug list or it may not, and when it is, it often sits on a higher tier with a larger copay. Medicare drug plans commonly shift brand-name drugs to pricier tiers once a generic equivalent is available.6Medicare.gov. How Drug Plans Work
In practice, pharmacies dispense the generic unless the prescription says otherwise, and the generic is therapeutically identical. If there is a specific medical reason you need the brand, your prescriber can file a tiering exception with your plan.6Medicare.gov. How Drug Plans Work
What You’ll Pay
Your out-of-pocket cost depends on the plan, but because generic nystatin usually lands on Tier 1, copays tend to be modest — often well under the roughly $26 average full cost of a nystatin prescription in Part D.3CDC. Prescribing of Topical Antifungals for Medicare Part D Beneficiaries
Without insurance, prices differ sharply by version:
- Brand-name Nystop (60g): average retail price around $180.7SingleCare. Nystatin Without Insurance
- Generic nystatin powder (60g): average retail about $56, with discount programs bringing it as low as $22. Some discount cards price generic nystatin in the $13 to $22 range.8GoodRx. Nystop Pricing9Drugs.com. Nystop Price Guide
Because discount-card prices for generic nystatin can run below a typical Part D copay, it is worth checking the cash price before running the prescription through insurance.
Extra Help for Low-Income Beneficiaries
Medicare’s Extra Help program, also called the Low-Income Subsidy, cuts prescription costs significantly. In 2026, qualifying beneficiaries pay no Part D deductible or monthly premium, and generic copays are capped at $5.10. Those with income below $1,350 per month or full Medicaid coverage pay as little as $1.60 for generics.10Medicare Interactive.

How to Check Your Plan and What to Do If Coverage Is Thin
Every Part D and Medicare Advantage plan has its own formulary, so the only way to know for sure is to check yours. Medicare’s Plan Finder at medicare.gov/plan-compare lets you enter your prescriptions and pharmacies and see what each plan covers, any restrictions, and estimated annual costs.12CCHICAP. Using Medicare Plan Finder You can also call the number on your Medicare plan card or dial 1-800-MEDICARE.13Medicare Rights Center. Use Medicare Plan Finder
If your plan doesn’t cover Nystop, or puts it on an expensive tier, you have options:
- Ask for the generic. Most plans cover generic nystatin powder at Tier 1, and it’s the same medication.
- Request a formulary or tiering exception. Your prescriber can submit a request asking the plan to cover a specific formulation or apply a lower copay.6Medicare.gov. How Drug Plans Work
- Compare the cash price with a discount card against your copay.
- Switch plans during Open Enrollment, which runs October 15 through December 7, with changes effective January 1.13Medicare Rights Center. Use Medicare Plan Finder
A Note on OTC Antifungal Powders
Some Medicare Advantage plans include an over-the-counter benefit that covers antifungal powders, creams, and sprays. One 2026 Medicare Advantage OTC catalog, for example, lists antifungal powder at $9 and clotrimazole 1% cream at $8, purchasable with the plan’s OTC benefit card.14THP Medicare. 2026 OTC Item Catalog
These are not substitutes for Nystop. Nystatin targets Candida yeast specifically, while OTC options like clotrimazole and miconazole cover a broader range of fungi, including the molds behind athlete’s foot and ringworm.15GoodRx. Nystatin vs Clotrimazole If your prescriber chose nystatin, there was likely a reason — usually a yeast infection or a moist skin fold where the powder works best. Switching to an OTC product is a conversation to have with the doctor who wrote the prescription, not a straight swap.
