📖 Nystatin: Patient Information Guide
A plain-language walkthrough of Nystatin — what it treats, how it works, how it’s taken, side effects, warnings and interactions. Tap any section to expand it.
🎯What it's used for▾
Nystatin is an antifungal used across several forms to treat Candida yeast infections in different parts of the body.
- Topical creams (Mycostatin, Nystatin Cream, Nystatin): treat Candida infections of the skin and mucous membranes
- Nystatin ointment: treats cutaneous or mucocutaneous Candida infections of the skin
- Topical powders (Klayesta, Nyamyc, Nystop, Nystatin Topical Powder, Nystatin): treat skin and mucocutaneous Candida infections; particularly useful for moist lesions
- Nystatin Oral Suspension and Nystatin oral suspension: treat candidiasis (yeast infection) in the mouth and oral cavity
- Nystatin tablets: treat non-esophageal mucous membrane gastrointestinal candidiasis (Candida infections of the GI tract lining, excluding the esophagus)
⚙️How it works▾
Nystatin targets the cell membrane of Candida fungi. It binds to sterols — structural fats in the membrane — and punches holes in it. This causes the fungal cell's contents to leak out, which kills the organism or stops it from growing. Because human cells use different sterols, nystatin selectively harms fungal cells. It does not work against bacteria, viruses, or protozoa.
Nystatin is not absorbed through intact skin or mucous membranes, so topical forms act locally. Candida albicans generally does not develop resistance to nystatin during treatment, though some other Candida species (such as C. tropicalis and C. krusei) can become resistant — though this resistance tends to reverse once the drug is stopped.
💊How it's taken▾
Dosing and how you take nystatin depends entirely on the form your prescriber chooses.
- Oral suspension: Taken four times a day; swish in the mouth as long as possible before swallowing. For infants, use the dropper to place half the dose in each side of the mouth.
- Tablets: Taken three times a day by mouth.
- Topical creams and ointment: Applied to the affected skin area twice daily.
- Topical powders: Dusted onto affected areas two or three times daily; for foot infections, also apply inside footwear.
For all forms, keep treating for at least 48 hours after symptoms clear to help prevent the infection from returning. Follow your prescriber's exact instructions.
🤒Side effects — in detail▾
Side effects with nystatin are uncommon — reported in fewer than 1 in 1,000 users of topical forms.
- Burning at the application site
- Itching
- Skin rash
- Eczema (skin inflammation)
- Pain on application
- Allergic reactions
- Nausea or gastrointestinal upset (reported with very high oral doses only)
If you develop a significant rash, swelling, or signs of a serious allergic reaction, stop using nystatin and contact your doctor right away.
⚠️Warnings & precautions▾
- Allergy: Do not use nystatin if you've had an allergic reaction to it or any ingredient in the product.
- Right form for the right place: Topical creams, ointments, and powders are for skin use only — never use them in the eyes, take them by mouth, or use them vaginally. Each form is approved only for its indicated route.
- Resistance: Some Candida species can become resistant during treatment. If your infection isn't improving, let your prescriber know.
🔀What it interacts with▾
The FDA label for nystatin does not identify specific drug, food, or supplement interactions.
This is not a complete list of interactions. Always talk with your doctor or pharmacist before starting, stopping, or changing any medication.
📋Before taking it▾
- Tell your prescriber if you have ever had an allergic reaction to nystatin or to any ingredient in the preparation — using it again could cause a serious reaction
- Topical nystatin forms are safe for neonates (newborns) and older children as well as adults, but always follow the specific directions for age group
- Do not use topical nystatin in the eyes, take it orally (unless it is the oral form), or use it vaginally — it is not approved for those routes
🚑If you take too much▾
Oral doses of nystatin much higher than what is typically prescribed have caused nausea and gastrointestinal upset. If you think someone has taken too much, contact a poison control center or seek medical attention promptly.
📡Pharmacodynamics — effects in the body▾
Nystatin is both fungistatic (stops fungal growth) and fungicidal (kills fungi) against a wide range of Candida and other yeast-like fungi. It works by disrupting the fungal cell membrane, causing contents to leak out. It has no meaningful activity against bacteria, viruses, or protozoa, so it won't treat bacterial infections.
🔬Pharmacokinetics — how your body processes it▾
Nystatin is not absorbed through intact skin or mucous membranes. This means topical forms work locally at the site of application and do not enter the bloodstream in significant amounts, which limits systemic (whole-body) side effects from topical use.
📦How to store it▾
Nyamyc® (Nystatin Topical Powder, USP) Store at 20° to 25°C (68° to 77°F); excursions permitted to 15° to 30°C (59° to 86°F) . Avoid excessive heat (40°C/104°F). Keep out of reach of children.

📈 How widely Nystatin is used
A general measure of how commonly Nystatin is prescribed, based on Medicaid — one of the largest public drug programs. The figure below is prescriptions filled in Q1–Q4 2025, summed across every form and brand of the drug.
Think of this as a proxy for how widely Nystatin is used, drawn from freely available public data. Medicaid is just one program — these numbers don’t include Medicare, other government coverage, or commercial and cash-pay prescriptions, so real-world use is higher than what’s shown here.
How commonly is Nystatin prescribed? Of the 1,596 medications we measure, Nystatin ranks #102 by Medicaid prescriptions — more than 94% of them.
Utilization by Nystatin product
Pick a product to see its own Medicaid numbers. Each chip is one clinical product — a specific strength & dosage form as defined by RxNorm — with brand-name and generic versions combined.
nystatin 100000 UNT/ML Topical Cream Most dispensed
Summed across the 10 of 56 listed NDC products with Medicaid activity — every brand and generic of this exact strength & form. RxNorm 543546
nystatin 100 UNT/MG Topical Powder
Summed across the 20 of 59 listed NDC products with Medicaid activity — every brand and generic of this exact strength & form. RxNorm 646456
nystatin 100000 UNT/ML Oral Suspension
Summed across the 9 of 101 listed NDC products with Medicaid activity — every brand and generic of this exact strength & form. RxNorm 312055
nystatin 100 UNT/MG Topical Ointment
Summed across the 12 of 28 listed NDC products with Medicaid activity — every brand and generic of this exact strength & form. RxNorm 884308
nystatin 500000 UNT Oral Tablet
Summed across the 2 of 21 listed NDC products with Medicaid activity — every brand and generic of this exact strength & form. RxNorm 312059
Shares are of the Medicaid prescriptions shown here. Product grouping follows RxNorm (the National Library of Medicine’s drug terminology), so “one product” means one strength & dosage form regardless of manufacturer. Dollar figures are gross Medicaid reimbursement before mandatory rebates — rebates (often large, especially for brand-name drugs) are confidential, so actual net cost to Medicaid is lower than shown.
Source: Medicaid State Drug Utilization Data (CMS), aggregated by generic ingredient — summed across every NDC (all brands, strengths, salt forms and dosage forms) of Nystatin, and across all states and both fee-for-service and managed-care claims. A general popularity signal; it excludes Medicare, commercial insurance and cash prescriptions, so it is not total U.S. use. Based on the 53 of 265 listed Nystatin NDCs with Medicaid activity.

📈 What people report — real-world data (FDA FAERS)
After a medicine reaches the market, patients, doctors and drugmakers can send the FDA reports of problems they think may be linked to it. Here’s what’s been reported for Nystatin — a signal of what to watch for, not proof the drug caused it.
Source: openFDA, from the FDA Adverse Event Reporting System (FAERS). These are voluntary reports — they don’t prove the drug caused the effect, and counts reflect how often something was reported, not how often it actually happens. Reports also often name the very problem the medicine is taken for — a common reason to file one is that the drug didn’t help — so for a pain reliever you may see “pain” high on the list; that points to why the report was filed, not to the drug causing the symptom. This counts every report that lists Nystatin in any role, so the total runs higher than the FDA’s official dashboard, which counts only cases where the drug is the suspect. For the authoritative figures, see the FDA FAERS Public Dashboard. Always talk to your pharmacist or doctor.

🔬 Where this comes from
Core label, product, RxNorm, safety, and utilization data on this page come from the sources identified below. AI-written, editorial, and licensed sections are labeled separately.
How we combine label and product data
HelloPharmacist combines public FDA and NLM records; we don’t author the underlying clinical facts. We identified 70 FDA-filed SPL label sets within the page’s selected clinical scope after exact ingredient or ingredient-combination matching and applicable route/form matching. The representative label is the starting point for the displayed reference monograph; the 12 largest stored in-scope SPL records, which may include that representative, are compared section by section, and the longest available version of each section is retained. Forms, routes, brands, labelers, product-listed strengths, and product-record counts are aggregated separately from ingredient-matched FDA NDC Directory records; package records listed above are associated with the linked SPL; and the normalized concept hierarchy comes from NLM RxNorm.
For canonical ingredient pages, bounded product-attributed indication and administration excerpts may be added to the AI evidence, and the generator is instructed to preserve available product, brand, route, and form qualifiers instead of treating one label as universal. Where a section is identified as AI-written, its plain-language text is generated from bounded label evidence. New draft drug pages remain in the admin review queue before first publication. Upsher-Smith Laboratories, LLC is the representative DailyMed label linked for verification and dates; it is not the sole source used for the page.
This is general education, not medical advice — always consult your doctor or pharmacist about your medications and any medical condition. For the exact wording of the linked representative label, view that label on DailyMed; some displayed composite sections may come from other in-scope SPL labels.
