The Pharmacist’s Take By · Clinical pharmacist · Written

Nystatin is an antifungal for Candida yeast infections of the skin, mouth or gut, depending on the form. It latches onto sterols (fat-like building blocks) in the yeast cell wall and makes it leaky, and having been on the market since about 1964 and available as a generic, it is a familiar standby and a common first choice for mild thrush and skin-fold yeast rashes. Very little gets absorbed into the body, so it is very well tolerated, and the occasional complaint is burning, itching or rash where it goes on. Stop it and call your doctor if you notice an allergic reaction, such as a worsening rash, swelling or severe itching.

Clinical pearls

  • For thrush, split the liquid between both sides of the mouth and hold it there as long as possible before swallowing.
  • For babies, give the liquid with a dropper and hold off feeding for 5 to 10 minutes afterward.
  • Powder suits very moist rashes and can be dusted inside shoes for foot yeast, while cream beats ointment in skin folds.
  • Keep going until the rash or white patches are fully gone, not just fading, since yeast stopped early can return.

Patient information guide A plain-language walkthrough of Nystatin, written from its FDA label.

What Nystatin is used for

▾

Nystatin is an antifungal used for Candida yeast infections. The exact use depends on the product.

  • Topical cream, ointment and powder (including Mycostatin, Nyamyc, Nystop and Klayesta): Candida infections of the skin or mucous membranes.
  • Nystatin Oral Suspension: Candida infection in the mouth.
  • Nystatin tablets: Candida infection of the digestive tract lining, not including the esophagus.

Topical products are not for whole-body, oral, vaginal or eye infections.

How Nystatin works

▾

Nystatin binds to sterols in the cell wall of yeast. This changes how leaky the wall is, and the cell’s contents spill out. It can both slow yeast growth and kill yeast.

Candida albicans does not generally become resistant during treatment. Some other Candida species can become resistant, and they may also resist amphotericin. That resistance fades once nystatin is stopped.

Nystatin dosage

▾

The form decides how you use it. Always follow your prescriber and the product label.

  • Oral suspension: about four times daily. Swish half in each side of the mouth and hold it as long as possible before swallowing.
  • Tablets: about three times daily, continued at least 48 hours after cure.
  • Cream or ointment: twice daily until healed.
  • Topical powder: two or three times daily until healed, including inside footwear for foot infections.

Dosing details from the FDA-approved label

From the Nystatin prescribing information (“Dosage and Administration”). Doses are set by your prescriber for your product, condition, kidney function and age — never change a dose on your own.

  • Oral suspension: Infants
    • 2 mL (200,000 units) four times daily
    • In infants and young children, use dropper to place one-half of dose in each side of mouth
    • Avoid feeding for 5 to 10 minutes; limited clinical studies in premature and low birth weight infants indicate that 1 mL four times daily is effective
  • Oral suspension: Children and Adults
    • 4 to 6 mL (400,000 to 600,000 units) four times daily (one-half of dose in each side of mouth)
    • Retain in the mouth as long as possible before swallowing; continue for at least 48 hours after perioral symptoms have disappeared and cultures demonstrate eradication of Candida albicans
  • Oral tablets: usual therapeutic dosage
    • One to two tablets (500,000 to 1,000,000 units nystatin) three times daily
    • Continue for at least 48 hours after clinical cure to prevent relapse
  • Topical powder: Adults and Pediatric Patients (Neonates and Older)
    • Apply to candidal lesions two or three times daily until healing is complete
    • Very moist lesions are best treated with the powder; for fungal infection of the feet, dust on the feet and in all foot wear
  • Topical cream: Adults and Pediatric Patients (Neonates and Older)
    • Apply liberally to affected areas twice daily or as indicated until healing is complete
    • Very moist lesions are best treated with nystatin topical dusting powder
  • Topical ointment
    • Apply liberally to affected areas twice a day or as indicated until healing is complete
    • Cream is usually preferred in candidiasis involving intertriginous areas; very moist lesions are best treated with topical powder
Read the label’s full dosing text

DOSAGE AND ADMINISTRATION Very moist lesions are best treated with the topical dusting powder. Adults and Pediatric Patients (Neonates and Older): Apply to candidal lesions two or three times daily until healing is complete. For fungal infection of the feet caused by Candida species, the powder should be dusted on the feet, as well as, in all foot wear.

Nystatin side effects

▾

Side effects from topical nystatin are uncommon. When they occur, they can include:

Common side effects

  • Burning where applied
  • Itching
  • Rash
  • Eczema
  • Pain on application
  • Allergic reactions

When to get medical help

  • Seek medical help if you develop signs of an allergic reaction, such as a worsening rash, swelling or severe itching.
  • Call your doctor if burning, itching or pain gets worse after you start using it.
  • Call your doctor if the infection does not clear with treatment.

Nystatin warnings and precautions

▾

Do not use nystatin if you are allergic to any of its ingredients.

Topical nystatin is not for infections that involve the whole body, or for the mouth, vagina or eyes.

Before taking Nystatin

▾
  • Tell your doctor if you have ever had an allergic reaction to nystatin or any ingredient in the product.
  • Do not use topical nystatin in the mouth, vagina or eyes.
  • Infants and children can use oral suspension and topical products, following label directions.

Nystatin overdose

▾

Oral doses above five million units a day have caused nausea and stomach upset. Contact a pharmacist, doctor or poison control if you take too much.

What Nystatin does in the body

▾

Nystatin is both fungistatic (stops yeast growing) and fungicidal (kills yeast) in lab tests. It works against many yeasts and yeast-like fungi, including several Candida species. It has no appreciable activity against bacteria, protozoa or viruses.

How your body processes Nystatin

▾

Nystatin is not absorbed from intact skin or mucous membranes. It stays at the site where it is applied.

How to store Nystatin

▾

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.

Nystatin: pharmacist answers to common questions

Quick, plain-English answers to the questions patients ask most about Nystatin — the kind of thing our pharmacy team would talk through with you at the counter.

What is nystatin treating?

▾
It treats Candida yeast infections. Creams, ointment and powder are for the skin. The liquid is for the mouth. Tablets are for the digestive tract lining.

How do I use the liquid for a mouth infection?

▾
Place half the dose in each side of your mouth and keep it there as long as you can before swallowing. For babies, use the dropper and avoid feeding for 5 to 10 minutes. Keep going for at least 48 hours after symptoms are gone, unless your prescriber says otherwise.

How often do I apply the cream or powder?

▾
Cream and ointment are usually applied twice a day. Powders are used two or three times a day. Keep using it until the area has healed, and follow your prescriber’s directions.

Will it cause side effects?

▾
Side effects are uncommon. Some people notice burning, itching, rash or pain where it is applied. Call your doctor if these show up or get worse.

Who should not use it?

▾
Anyone who has had an allergic reaction to nystatin or its ingredients should avoid it. Topical forms are not for the mouth, vagina or eyes.

What if I take too much by mouth?

▾
Very large oral amounts, over five million units in a day, have caused nausea and stomach upset. If you think you took too much, call your pharmacist, doctor or poison control.

Is Nystatin available over the counter?

▾
No. Nystatin is a prescription medicine: every Nystatin product listed with the FDA is prescription only, so it is not sold over the counter. Your prescriber decides whether it is appropriate for you, and your pharmacist dispenses it.

When was Nystatin first available?

▾
The earliest FDA record we hold for Nystatin is from 1964: its first approval in Drugs@FDA or its earliest product listing in the NDC Directory, whichever is older. Many older medicines were in use before their first formal FDA approval, so this is the earliest date on record, not necessarily when Nystatin was first used.

Who makes Nystatin?

▾
39 companies currently list Nystatin products in the FDA's NDC Directory, including Bryant Ranch Prepack, A-S Medication Solutions, NuCare Pharmaceuticals,Inc.. That count includes repackagers and distributors as well as manufacturers (companies that sell only the raw ingredient are not counted), so fewer companies actually make it; the label on your bottle names the one that supplied yours.

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.

Nystatin recall history

A recall is when a specific batch of a medicine is pulled from the market — usually a manufacturing issue, not a problem with the drug itself. Class I is most serious, Class III least.

The FDA’s enforcement reports list 2 Nystatin recalls since July 2021. One of them is still ongoing and is listed first. A recall names specific lots from one company, so check the lot number on your own bottle rather than assuming every product is affected; your pharmacist can check whether your supply came from an affected lot.
