Thrush

Thrush is a common fungal infection that affects both men & women. To help prevent thrush, it's important to maintain good hygiene practices. If you suspect you have thrush, Boots offers different thrush treatment options. With medication, the thrush should clear up within a week but if it doesn’t, you should visit your GP.

Symptoms of thrush


    Thrush can cause discomfort, itching, and pain, and may be accompanied by discharge or a rash. In women, thrush can cause common symptoms such as:

  • An itchy vagina 
  • Soreness around the entrance of your vagina (the vulva)
  • Swelling of your vaginal lips (the labia)
  • Thick discharge
  • Pain when you wee
  • Pain during sex

It's important to note that not everyone with thrush will experience all of these symptoms, and some people may have no symptoms at all. If you’re experiencing any of these symptoms along with a fever, chills, nausea, vomiting and abdominal pain, you should see your GP straight away.

Oral thrush is a common fungal infection that affects the mouth and throat. In the mouth, thrush appears as white patches on the tongue, gums, or inside of the cheeks. These patches may be painful and can cause difficulty swallowing, as well as a loss of taste. Oral thrush can occur in people of all ages, but it is most common in infants and older adults.

There are several factors that can increase the risk of developing oral thrush. Poor oral hygiene, smoking, wearing dentures that don't fit properly, and having a weakened immune system can all contribute to the development of thrush. Additionally, taking antibiotics or certain medications that suppress the immune system can increase the risk of thrush.

With vaginal thrush comes a discharge that you shouldn’t normally see. Your discharge can turn yellow or stay white but be quite a lot thicker than usual (usually a cottage cheese consistency).

Men may experience redness, itching, and irritation on the penis. Find out more about male thrush.

Causes of thrush


Thrush is caused by a yeast fungus called candida, but don’t worry, it’s usually harmless. Candida loves warm, moist conditions. Your vagina can be the perfect breeding ground for thrush if the balance of your good bacteria that normally keep the fungus under control is disturbed. The main reason for getting thrush is because your balance of bacteria changes, but the following can also affect your bacteria balance:

  • If you're taking antibiotics
  • Irritated skin
  • Weakened immune system
  • Menopause
  • Pregnancy
  • If you've got a UTI (urinary tract infection)


While thrush isn’t a sexually transmitted disease, it can be triggered and sometimes passed on through sex. So, for that reason, you should avoid sex whilst you have thrush.

Thrush treatments


The most common treatment for thrush is antifungal medications. You can buy antifungal medicine from your local Boots pharmacy if you’ve been diagnosed with thrush in the past and know your symptoms. Our pharmacists are on hand to help recommend the best treatment for you. If discussing your symptoms makes you uncomfortable, our private consultation rooms offer a discreet space to address your concerns.

How do I treat recurring thrush infections?


If you have recurring thrush infections it is important that you do not self-treat and see your GP to determine the underlying cause and develop a more targeted treatment plan. With medication, the thrush should clear up within a week but if it doesn’t see your GP.

When should I see a doctor for thrush?

Early diagnosis and treatment can help prevent the infection from worsening and causing further discomfort. Additionally, some symptoms of thrush can be similar to those of other conditions, such as sexually transmitted infections, so it's important to get a proper diagnosis to ensure you receive the appropriate treatment.

You should also consult your doctor if you've tried over-the-counter treatments for thrush and your symptoms haven't improved, or if your symptoms worsen after starting treatment. 

If it's your first time or if you get it more than twice in six months, see your GP. If you’re pregnant and you get thrush, you should also see your GP or midwife.


Recurrent thrush infections may indicate an underlying health issue that needs to be addressed. Your doctor can help determine the cause of your symptoms and recommend the best course of action for your individual situation.

Preventing & managing thrush


From wearing cotton underwear to avoiding soaps or shower gels, there are certain things you can do to stop thrush from coming back.

Frequently asked questions

Thrush isn’t a sexually transmitted infection (STI), but it can be triggered and sometimes passed on through sex. It's important to note that some STIs can cause symptoms similar to those of thrush, such as genital itching and discharge.

If you are experiencing these symptoms and have had unprotected sex, it's important to get tested for STIs to rule out any potential infections, either by booking a visit to your local sexual health clinic or with an with a Boots Online Doctor STI Home test kit.5

Practising safe sex and getting regular STI testing can help reduce your risk of both conditions.

Men can also get thrush, not just through having sex with someone who already has it, (although this is the most common way) but through a disturbance of good bacteria. Just as a woman’s vagina can make a nice home for candida (the fungus previously discussed), so can the nice warm moist area of the penis. In men, thrush can cause redness, itching, and irritation on the penis. It may also cause a white, lumpy discharge that resembles cottage cheese. 

It's generally recommended that you avoid using tampons until the infection has cleared up. This is because tampons can irritate the vaginal area and potentially worsen symptoms of thrush. Additionally, tampons can absorb medication used to treat thrush, making it less effective.

Instead of using tampons, it's recommended that you use sanitary pads or panty liners until your thrush infection has been fully treated. You may also want to consider wearing loose-fitting clothing made from breathable fabrics like cotton, which can help reduce irritation and promote healing.

Thrush can sometimes come back after treatment, especially if the underlying cause of the infection is not addressed. For example, if thrush is caused by a weakened immune system or an uncontrolled medical condition like diabetes, it may be more likely to recur. Additionally, if you do not complete the full course of medication prescribed for your thrush infection, it may not be fully cleared up and could return.

To prevent thrush from coming back after treatment, it's important to address any underlying health issues that may be contributing to the infection. 

Thrush is not typically considered a contagious condition. However, it's important to note that some types of yeast infections can be spread through sexual contact. For example, men can develop thrush on the penis after having unprotected sex with a partner who has a vaginal yeast infection.

Additionally, babies can sometimes develop thrush after coming into contact with yeast in their mother's breast milk. If you are concerned about the potential for thrush to be spread to others, talk to your GP about steps you can take to reduce the risk of transmission and maintain good overall health.

If you have thrush, it's generally recommended that you avoid having sex until the infection has cleared up. This is because sexual activity can cause further irritation and discomfort in the affected area, potentially prolonging the healing process. Additionally, engaging in sex while you have thrush may increase the risk of passing the infection to your partner, especially if you're not using barrier protection like condoms. Once your symptoms have resolved and you've completed the full course of treatment prescribed by your doctor, it should be safe to have sex again. 

Vaginal itching is a common symptom that many women experience at some point in their lives. It can be caused by a variety of factors, ranging from mild irritations to more serious medical conditions. Some common causes of vaginal itching include yeast infections, bacterial vaginosis, sexually transmitted infections, and skin irritations from soaps, detergents, or personal care products.

If you're experiencing vaginal itching, it's important to pay attention to any accompanying symptoms and consult your doctor for a proper diagnosis. They can help determine the underlying cause of your discomfort and recommend the most appropriate treatment plan. In some cases, over-the-counter remedies may be sufficient to alleviate itching, while other situations may require prescription medications or further medical intervention. By addressing the root cause of the itching, you can work towards finding relief and maintaining good overall health.
