Nystatin for oral thrush

About nystatin suspension

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.
