Vaginal Thrush Treatment

Thrush is caused by candida, a type of yeast that's naturally present in the vagina, gut and skin of most people without causing any problems at all. Symptoms only appear when something disrupts the normal balance of bacteria and yeast, allowing candida to multiply. This is why thrush isn't something you catch from someone else in the usual sense, even though sexual contact can sometimes trigger an episode.

A number of everyday things can tip that balance. Taking a course of antibiotics is one of the most common triggers, since antibiotics kill off the bacteria that normally keep yeast in check. Pregnancy raises the risk too, because higher oestrogen levels change the vaginal environment. Poorly controlled diabetes, a weakened immune system, and hormone replacement therapy are also recognised risk factors, according to the NHS. Tight, non-breathable underwear and washing with soap or shower gel rather than water can make the area more prone to irritation as well, even if they don't cause thrush on their own.

Most women recognise thrush from the symptoms alone once they've had it confirmed the first time. The clearest signs are a thick, white vaginal discharge that's often compared to cottage cheese and doesn't usually smell, along with itching, soreness and irritation around the vulva and entrance of the vagina. Some people also notice stinging when they pee or discomfort during sex.

As part of our online consultation, you'll describe your symptoms and answer some questions about your medical history and whether this is a one-off episode or something that keeps recurring. Our pharmacist reviews this against clinical guidance to confirm whether over-the-counter treatment is appropriate. If your symptoms don't fit the usual pattern, if this is your first ever episode, or if you're under 16, over 60, pregnant, or have a weakened immune system, we'll recommend seeing a GP instead, in line with NHS guidance on when self-treatment isn't the right first step.

Treatment works by killing off the excess yeast causing the infection, and comes in three main forms: an external cream, a pessary you insert into the vagina, or a capsule you swallow. Creams containing clotrimazole are applied directly to the affected area and are good for easing external itching and soreness quickly, though they mainly treat symptoms on the skin rather than the underlying infection. A pessary delivers the antifungal medicine directly inside the vagina, working on the infection at its source, and our Combi option pairs this with an external cream so you get relief from itching alongside internal treatment. The oral capsule contains fluconazole and works from within the body after a single dose, with no applicator needed, which some people find more convenient.

Most cases clear up within 7 to 14 days of starting treatment, whichever option you choose. If you're prone to thrush coming back, it's worth knowing that treating it fully the first time, rather than stopping as soon as symptoms ease, gives the best chance of it not returning straight away.

Clearing an active infection is only part of the picture. Because candida is naturally present and simply needs the right conditions to overgrow, small daily habits make a real difference to how often thrush comes back. Washing the area with plain water or an emollient rather than soap, shower gel or scented washes helps avoid disturbing the natural balance further. Drying properly afterwards, wearing cotton underwear rather than synthetic fabrics, and avoiding tight-fitting underwear or tights all reduce the warm, moist conditions candida prefers.

If thrush keeps coming back, defined by the NHS as more than 4 episodes in 12 months, it's worth speaking to a GP rather than repeatedly self-treating. Recurring thrush sometimes needs a longer course of treatment, up to 6 months in some cases, and a GP can also check whether something else, such as diabetes or another underlying condition, is contributing
