Thrush is a common yeast infection that affects men and women. It's usually harmless but it can be uncomfortable and keep coming back. It is not classed as a sexually transmitted infection (STI).
You can buy antifungal medicine from pharmacies if you've had thrush diagnosed in the past and you know the symptoms.
A pharmacist can recommend the best treatment for you. Ask if they have a private area to talk if you're embarrassed.
You should not use antifungal medicine more than twice in 6 months without speaking to a pharmacist or doctor.
