What might I notice if I have it (Symptoms)?

Candida albicans/yeast usually lives harmlessly on the skin and in the mouth, gut, and vagina. Occasionally, however, signs and symptoms can develop. This is commonly known as thrush, thrush infection or candida. 
Your chances of developing thrush increase if you:

  • are pregnant
  • wear tight clothing (such as tight jeans) or synthetic clothing (such as nylon underwear)
  • are taking antibiotics
  • are having chemotherapy
  • have uncontrolled diabetes, HIV or other illnesses that affect your immune system
  • use products that may irritate the vagina, such as vaginal deodorant or perfumed bubble bath or shower gel

How do I get tested?

It’s not always necessary to have a test for thrush. If you do have a test, a doctor or nurse may:

  • look at the genital area, the vagina or the penis
  • use a swab to collect a sample from the vagina
  • use a swab to collect a sample from the penis and genital area, including under the foreskin.

A swab looks like a cotton bud, but is smaller, soft and rounded. The swab is wiped over the parts of the body that could be affected and easily picks up samples. It only takes a few seconds and isn’t usually painful, though it may be uncomfortable for a moment.

Sometimes it’s possible for you to get the test result straight away. Otherwise you’ll have to wait up to two weeks to get your result.

What is the treatment?

Treatment is simple and only necessary if you have signs and symptoms of thrush.

  • You may be given antifungal cream to apply to the genital area, vaginal pessaries (tablets that you put into your vagina), pills or a combination. The doctor or nurse will tell you how to use the treatment.
  • You can buy some antifungal treatments from a pharmacy – these are useful if you’re sure you have thrush and want to treat it yourself. The pharmacist will answer any questions and explain how to use the treatment.
  • It’s very important to take the treatment as instructed and finish any course of treatment even if the symptoms go away earlier.
