What is it?

Nystatin is a medication used to treat fungal infections of the mouth, skin, vagina, and intestinal tract.

Before using Mycostatin 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, such as herbal and complementary medicines.
  • If you have ever had an allergic reaction to a medicine.
  • If you are pregnant or breast-feeding. Nystatin is not known to be harmful during pregnancy or breast-feeding, but it is still important that you tell your doctor.

How to use Mycostatin 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 drops exactly as your doctor tells you to. The recommended dose is 1 ml (to the line on the dropper) four times daily. This dose is suitable both for adults and for children. It will be different to this if the drops have been prescribed for a very young baby. Space the doses evenly throughout the day.
  • 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.
