What is nystatin?

Nystatin is an antifungal medication that fights infections caused by fungus.

Nystatin when taken by mouth is used to treat yeast infections in the mouth or stomach.

Oral nystatin is not absorbed into your bloodstream and will not treat fungal infections in other parts of the body or on the skin.

Nystatin may also be used for purposes other than those listed in this medication guide.

Important Information

Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

Before taking this medicine

You should not use nystatin if you are allergic to it.

How should I take nystatin?

Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

About nystatin suspension

Type of medicine An antifungal medicine
Used for Treatment of thrush in the mouth or throat
Also called Nystan®
Available as Oral suspension (drops)

Thrush is an infection caused by the Candida yeast fungus. The mouth is a common site where Candida causes infection. Candidal infection in the mouth is called oral thrush. The infection causes the mouth to become sore and red, and white spots sometimes develop.

Small numbers of Candida commonly live in a healthy mouth and are usually harmless. However, certain situations or conditions can cause an overgrowth of Candida and this can lead to a bout of oral thrush. These include wearing dentures, after a course of antibiotics, using corticosteroid inhalers, having diabetes or anaemia, being in poor health, and smoking. It is also quite common for young babies to have oral thrush.

Nystatin suspension (drops) are an option for the treatment of oral thrush. Nystatin works by killing the Candida fungus which is causing the mouth infection.

Before using nystatin suspension

To make sure this is the right treatment for you, before you start using nystatin it is important that your doctor knows:

  • If you are taking or using any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.
  • If you have ever had an allergic reaction to a medicine.
  • If you are pregnant or breastfeeding. Nystatin is not known to be harmful during pregnancy or breastfeeding, but it is still important that you tell your doctor.

How to use nystatin suspension

  • Before you start the treatment, read the manufacturer’s printed information leaflet from inside the pack. It will give you more information about how to use nystatin drops. If you have been given any additional information by your doctor, please read this also.
  • Use the suspension exactly as your doctor tells you to. It is to be used four times daily. Space the doses evenly throughout the day. Your doctor will tell you how many droppersful (ml) to use for each dose.
  • Shake the bottle well before you use the drops. Use the dropper to drop the liquid inside your mouth near to the affected areas but try not to touch your mouth with the dropper as you do this. Swish the suspension around your mouth a little and then keep it on the affected areas for as long as possible before you swallow. The longer the medicine is in contact with the site of infection the better.
  • It is recommended that you use the drops after mealtimes. This is to prevent the medicine from being washed out of your mouth too soon by anything you eat or drink.
  • If you forget to use the drops, have a dose as soon as you remember. Try to take the correct number of doses each day but do not take two doses at the same time to make up for a missed dose.
  • Most doctors recommend that you continue to use the drops for two days after your symptoms have gone – a typical course of treatment will last around seven days.

Getting the most from your treatment

  • If your symptoms have not improved after seven days of using the drops, make another appointment to speak with your doctor for further advice.
  • There are some things that you may be able to do to prevent further bouts of oral thrush. Please see the section ‘Can oral thrush be prevented?’ in the separate condition leaflets called Oral Thrush and Oral Thrush in Babies.

Can nystatin suspension cause problems?

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the ones associated with nystatin, although these occur only occasionally. You will find a full list in the manufacturer’s information leaflet supplied with your medicine. Speak with your doctor or pharmacist if any of the following continue or become troublesome.

Occasional nystatin side-effects What can I do if I experience this?
Mouth irritation or sensitivity Stop using the drops and speak with your doctor again
Feeling sick (nausea) or being sick (vomiting), diarrhoea Drink some water to replace any lost fluids. If it continues, speak with your doctor

If you experience any other symptoms which you think may be due to the medicine, please speak with your doctor or pharmacist for further advice.

How to store nystatin

  • Keep all medicines out of the reach and sight of children.
  • Store in a cool, dry place, away from direct heat and light.

How does this medication work? What will it do for me?

Nystatin belongs to the group of medications known as antifungals. Nystatin oral medications in liquid form are most often used to treat fungal infections in the mouth.

The liquid and tablets are used to treat a fungal infection of the intestine known as candidiasis. This occurs when the fungus known as Candida albicans overgrows in the intestine as a result of antibiotic or corticosteroid use. The medication may also be used to prevent fungal infections.

The powder can be used to make an oral liquid or added to creams or ointments. The skin cream and ointment are used to treat fungal skin infections. The vaginal cream and vaginal tablets are used to treat vaginal infections caused by Candida albicans.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

In some cases the solution should be held in the mouth for some time and gargled before swallowing.

For young infants and children, the solution may be mixed with milk, lukewarm formula, jam, or peanut butter. For adults, the usual dose is 400,000 to 600,000 units 4 times daily. Shake the bottle before use. Use an oral syringe to measure each dose of the liquid, as it gives a more accurate measurement than household teaspoons.

Skin cream or ointment: Apply cream or ointment liberally to affected areas twice daily or as prescribed by your doctor. Severe fungal infections may require the use of both oral and topical nystatin.

Vaginal cream: The usual dose is one full applicator (5 grams) inserted into the vagina daily. In severe infections, a dose of one applicator every 12 hours may be given. Usually, treatment is given for 2 weeks. Treatment should be continued during menstruation.

Vaginal tablets: The usual dose is one tablet inserted high into the vagina using the applicator, once or twice daily. Usually, treatment is given for 2 weeks. Treatment should be continued during menstruation.

To prevent a relapse, treatment should be continued for at least 48 hours after the symptoms go away, regardless of dosage form.

What is Nystatin oral suspension?

Nystatin oral suspension contains the antifungal medicine nystatin.

Nystatin oral suspension is used to treat infections of the mouth, throat and intestines with Candida species of fungi, in particular Candida albicans. These fungi are found naturally in the mouth and gut but can sometimes increase in numbers if the conditions in these areas change, and this can cause infection.

Nystan is a well-known brand name of nystatin oral suspension.

Nystatin oral suspension is only available on prescription in the UK.

How does Nystatin oral suspension work?

Nystatin kills fungi and yeasts by interfering with their cell membranes. It works by binding to a substance called ergosterol, which is an essential component of fungal cell membranes. This disrupts the cell membrane, causing holes to appear in it.

The cell membranes of fungi are vital for their survival. They keep unwanted substances from entering the cells and stop the contents of the cells from leaking out. As nystatin causes holes to appear in the cell membranes, essential constituents of the fungal cells can leak out. This kills the fungi and treats the infection.

Nystatin is not absorbed into the bloodstream, which allows it to act directly in the area of infection.

Nystatin Tablets Description

Nystatin is an antimycotic polyene antibiotic obtained from Streptomyces noursei. Its structural formula:

Nystatin Tablets are provided for oral administration as coated tablets containing 500,000 units nystatin.

Inactive ingredients: anhydrous lactose, carnauba wax, corn starch, D&C Yellow No. 10 Aluminum Lake, FD&C Blue No. 2 Aluminum Lake, FD&C Red No. 40 Aluminum Lake, hydroxypropyl cellulose, hypromellose, magnesium stearate, microcrystalline cellulose, polyethylene glycol, povidone, sodium starch glycolate, stearic acid, and titanium dioxide.

Nystatin Tablets – Clinical Pharmacology


Gastrointestinal absorption of nystatin is insignificant. Most orally administered nystatin is passed unchanged in the stool. In patients with renal insufficiency receiving oral therapy with conventional dosage forms, significant plasma concentrations of nystatin may occasionally occur.


Nystatin is both fungistatic and fungicidal in vitro against a wide variety of yeasts and yeast-like fungi. Candida albicans demonstrates no significant resistance to nystatin in vitro on repeated subculture in increasing levels of nystatin; other Candida species become quite resistant. Generally, resistance does not develop in vivo. Nystatin acts by binding to sterols in the cell membrane of susceptible Candida species with a resultant change in membrane permeability allowing leakage of intracellular components. Nystatin exhibits no appreciable activity against bacteria, protozoa, or viruses.

Indications and Usage for Nystatin Tablets

Nystatin Tablets are intended for the treatment of non-esophageal mucus membrane gastrointestinal candidiasis.


Nystatin Tablets are contraindicated in patients with a history of hypersensitivity to any of their components.



This medication is not to be used for the treatment of systemic mycoses. Discontinue treatment if sensitization or irritation is reported during use.

Carcinogenesis, Mutagenesis, Impairment of Fertility

No long-term animal studies have been performed to evaluate carcinogenic potential. There also have been no studies to determine mutagenicity or whether this medication affects fertility in males or females.


Teratogenic Effects

Category C

Animal reproduction studies have not been conducted with nystatin. It is also not known whether nystatin can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Nystatin should be given to a pregnant woman only if clearly needed.

Nursing Mothers

It is not known whether nystatin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when nystatin is administered to a nursing woman.

Adverse Reactions

Nystatin is well tolerated even with prolonged therapy. Oral irritation and sensitization have been reported. (See PRECAUTIONS: General.)


Diarrhea (including one case of bloody diarrhea), nausea, vomiting, gastrointestinal upset/disturbances.


Rash, including urticaria has been reported rarely. Stevens-Johnson syndrome has been reported very rarely.


Tachycardia, bronchospasm, facial swelling, and nonspecific myalgia have also been rarely reported.


Oral doses of nystatin in excess of five million units daily have caused nausea and gastrointestinal upset. There have been no reports of serious toxic effects of superinfections (see CLINICAL PHARMACOLOGY, Pharmacokinetics).

Nystatin Tablets Dosage and Administration

The usual therapeutic dosage is one to two tablets (500,000 to 1,000,000 units nystatin) three times daily. Treatment should generally be continued for at least 48 hours after clinical cure to prevent relapse.

Nystatin for Candida infection

This leaflet is about the use of nystatin for Candida infection, which is a type of fungal infection (caused by a yeast-like fungus). Candida is also commonly known as thrush. Nystatin is used to prevent or treat Candida infection in the mouth, throat and intestine.

This leaflet has been written for parents and carers about how to use this medicine in children. Our information sometimes differs from that provided by the manufacturers, because their information is usually aimed at adult patients. Please read this leaflet carefully. Keep it somewhere safe so that you can read it again.

Name of drug

Brand name: Nystan®

Why is it important for my child to take this medicine?

Candida (thrush) is an infection caused by a yeast-like fungus. Nystatin kills the fungus and so gets rid of the infection, or stops an infection from developing.

Some of the fungus may remain after the symptoms of the infection have gone. It is therefore important that you continue to give the medicine as your doctor has prescribed, to make sure that all the fungi are killed, otherwise the infection may come back. Please do not stop early.

What is nystatin available as?

Liquid medicine (suspension): 100,000 units in 1 mL; contains sucrose and may contain alcohol. If you have any concerns or questions, speak with your child’s doctor or pharmacist.

When should I give nystatin?

For treatment of an infection: When used to treat an infection, nystatin is usually given four times each day after food. This should be after breakfast, after lunch, after tea and at bedtime. These times should be at least 3 hours apart.

For prevention of infection: When used to prevent infection, nystatin is given once a day, after a meal. This should be at about the same time each day.

Give the medicine at about the same time(s) each day so that this becomes part of your child’s daily routine, which will help you to remember.

How much should I give?

Your doctor will work out the amount of nystatin (the dose) that is right for your child. The dose will be shown on the medicine label.

It is important that you follow your doctor’s instructions about how much to give.

How should I give nyastin?

Nystatin should always be given after a meal or some food, not before it.

  • Shake the medicine well. Measure out the right amount using an oral syringe or medicine spoon. You can get these from your pharmacist. Do not use a kitchen teaspoon as it will not give the right amount.
  • Put the medicine into your child’s mouth. They should keep it in their mouth for as long as possible – the longer it is in contact with the infected area, the better it will work.
  • Your child should then swallow or spit out the medicine, depending on what your doctor has told you to do.

Do not dilute the medicine or mix it with food or drink.

When should the medicine start working?

Your child should start to get better after taking the medicine for 2 days. They should continue to take the medicine even after they start to feel better, as it takes a while to kill all the fungus.

What if my child is sick (vomits)?

  • If your child is sick less than 30 minutes after having a dose of nystatin, give them the same dose again.
  • If your child is sick more than 30 minutes after having a dose of nystatin, you do not need to give them another dose. Wait until the next normal dose.

What if I forget to give it?

If you are giving it four times a day to treat an infection: If you miss a dose, wait until the next normal dose. Do not give the missed dose.

If you are giving it once a day to prevent infection: Give the missed dose as soon as you remember, as long as this is at least 12 hours before the next normal dose. You do not need to wake your child up to give a missed dose.

What if I give too much?

Nystatin is normally a safe drug and it is unlikely to cause any problems if you give an extra dose by mistake.

If you are worried that you may have given your child too much nystatin, contact your doctor or local NHS services (111 in England and Scotland; 0845 4647 in Wales). Have the medicine container or packet with you if you telephone for advice.

Are there any possible side-effects?

We use medicines to make our children better, but sometimes they have other effects that we don’t want (side-effects).

Nystatin may cause some minor side-effects when your child first starts taking it. These should wear off after a few days. If they are still a problem after a week, contact your doctor for advice.

  • Your child may get a skin rash or itching, although this is unlikely. You can apply an aqueous cream or cream for itching.
  • Your child may feel sick.
  • Your child’s mouth and throat may feel sore or feel irritated.

There may, sometimes, be other side-effects that are not listed above. If you notice anything unusual and are concerned, contact your doctor. You can report any suspected side-effects to a UK safety scheme at

Can other medicines be given at the same time as nystatin?

  • You can give your child medicines that contain paracetamol or ibuprofen, unless your doctor has told you not to.
  • Check with your doctor or pharmacist before giving any other medicines to your child. This includes herbal and complementary medicines.

Is there anything else I need to know about nystatin?

  • If your child is taking nystatin to treat an infection, it is important that they take the whole course of treatment. The Candida fungi may remain after your child starts to feel well; however, it is important to kill all the fungi to make sure that the infection doesn’t come back.
  • If your child has a dental brace or dentures, ask your doctor or pharmacist about how to clean them.
  • Never save medicine for future illnesses. Throw away any unused medicine or return it to the pharmacy.

General information about medicines

  • If you think someone else may have taken the medicine by accident, contact your doctor for advice.

Where should I keep this medicine?

  • Keep the medicine in a cupboard, away from heat and direct sunlight.
  • Make sure that children cannot see or reach the medicine.
  • Keep the medicine in the container it came in.
