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).
Check if you have thrush
Thrush symptoms in women
- white vaginal discharge (often like cottage cheese), which does not usually smell
- itching and irritation around the vagina
- soreness and stinging during sex or when you pee
Thrush symptoms in men
- irritation, burning and redness around the head of the penis and under the foreskin
- a white discharge (like cottage cheese)
- an unpleasant smell
- difficulty pulling back the foreskin
Thrush in other areas
Thrush can affect other areas of skin, such as the armpits, groin and between the fingers.
This usually causes a red, itchy or painful rash that scales over with white or yellow discharge. The rash may not be so obvious on darker skin.
Sometimes thrush causes no symptoms at all.

Non-urgent advice: See a GP or go to a sexual health clinic if:
- you have the symptoms of thrush for the first time
- you're under 16 or over 60
- thrush keeps coming back (more than 4 times in 12 months)
- treatment has not worked
- you're pregnant or breastfeeding
- you have thrush and a weakened immune system – for example, because of diabetes, HIV or chemotherapy
Sexual health clinics can help with thrush
Sexual health clinics treat problems with the genitals and urine system.
Many sexual health clinics offer a walk-in service, where you do not need an appointment.
They'll often get test results quicker than GP surgeries.
What happens at your appointment
The GP or sexual health clinic will want to confirm it's thrush and rule out other infections.
You'll be asked about your symptoms.
If it's not clear it's thrush:
- a doctor or nurse may look at your vagina, penis or skin
- a cotton bud may be wiped over the discharge to test for other infections
You'll usually need antifungal medicine to get rid of thrush. This can be a tablet you take, a tablet you insert into your vagina (pessary) or a cream to relieve the irritation.
Thrush should clear up within 7 to 14 days of starting treatment.
You do not need to treat partners unless they have symptoms.
You might need to take treatment for longer (for up to 6 months) if you keep getting thrush (you get it more than 4 times in 12 months).
A GP or sexual health clinic can help identify if something is causing your thrush, such as your period or sex.
They'll recommend how often you should use treatment.
A pharmacist can help with thrush
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.
Things you can do yourself to ease discomfort and prevent thrush returning
use water and emollient (like E45 cream) instead of soap to wash the affected area
dry properly after washing
wear cotton underwear
avoid sex until thrush has cleared up if sex is uncomfortable
do not use soaps or shower gels
do not use douches or deodorants on your vagina or penis
do not wear tight underwear or tights
If you have sex during treatment, be aware that antifungal creams can damage condoms and diaphragms. This means your contraception might not work.
What causes thrush
Thrush is not classed as a sexually transmitted infection (STI), but it can be triggered by sex.
Thrush is caused by a fungus called candida that is normally harmless.
Thrush tends to grow in warm, moist conditions and develops if the balance of bacteria changes.
This can happen if:
- your skin is irritated or damaged
- you're taking antibiotics
- you have poorly controlled diabetes
- you have a weakened immune system (for example, because of HIV or chemotherapy)
- you're having hormone replacement therapy (HRT)
- you're pregnant
