What is thrush?

ThrushThrush is a yeast infection and is the second most common cause of a vaginal discharge (the most common being Bacterial Vaginosis). It is caused by yeast called candida, small amounts of which commonly live on the skin and around the vaginal area.

This candida may invade the vagina and, under suitable conditions, can multiply, causing the unpleasant symptoms of thrush.

Treating thrush

There are many effective types of thrush treatment. If you think you have thrush, it is advisable to see your doctor immediately. If they diagnose the condition, you will probably be prescribed an anti-fungal cream and/or a vaginal pessary (a tablet you insert into your vagina); there is also an oral tablet, which some women prefer.

These methods of thrush prevention are also available from your pharmacist without a prescription.


There are some simple measures you can take, which could help prevent thrush:

  • Avoid excessive washing (or douching) of the vagina: this may alter the normal balance of bacteria, making symptoms more likely to develop
  • Avoid using perfumed intimate products as these can disrupt the natural vaginal balance
  • Avoid tight-fitting underwear or tights and wear cotton underwear and loose-fitting trousers and skirts
