Internal Treatment for Vaginal Thrush (Candidiasis)

Canesten Pessary Overview

Canesten Pessary is an antifungal treatment used to treat vaginal thrush, a common fungal infection caused by Candida species. It contains clotrimazole, which works by killing the yeast responsible for infection and relieving internal symptoms.

In the UK, Canesten Pessaries are available as an over-the-counter pharmacy medicine, commonly used when symptoms of thrush are clear and previously diagnosed.

Understanding Vaginal Thrush

What causes thrush

Vaginal thrush is caused by an overgrowth of Candida yeast, most commonly Candida albicans. This can occur when the natural balance of vaginal flora is disrupted, for example by antibiotics, hormonal changes, illness, pregnancy or immune changes.

Symptoms typically include internal irritation, soreness, abnormal discharge and itching, although itching is often more noticeable externally.

Why internal treatment is used

While creams treat external symptoms, pessaries deliver antifungal treatment directly inside the vagina, targeting the source of infection and helping clear yeast overgrowth more effectively.

What Is Canesten Pessary?

Canesten Pessary contains clotrimazole, a broad-spectrum antifungal medicine. It is designed for internal vaginal use, where it dissolves and releases medication directly at the site of infection.

Pessaries are often used as a single-dose or short-course treatment, depending on the strength supplied.

How Does Canesten Pessary Work?

Antifungal action

Clotrimazole works by interfering with ergosterol synthesis, an essential component of fungal cell membranes. Without ergosterol, yeast cells become damaged and are unable to survive.

Clearing infection at source

By treating the infection internally, the pessary helps reduce yeast levels within the vagina, supporting symptom resolution and reducing the risk of recurrence when used correctly.

What Canesten Pessary Helps With — and What It Does Not

What it helps with

Canesten Pessary is used to treat:

• vaginal thrush (candidiasis)
• internal vaginal yeast infection
• thrush symptoms such as soreness and discharge

It is most effective when symptoms clearly match thrush.

What it does not treat

Canesten Pessary does not:

• treat bacterial vaginosis
• relieve external symptoms alone
• prevent thrush from recurring
• treat sexually transmitted infections

External creams may be needed alongside internal treatment for full symptom relief.

Who Is Canesten Pessary For?

Canesten Pessary may be suitable for:

• adult women with previous thrush diagnosis
• individuals with typical thrush symptoms
• those preferring internal treatment

A pharmacist can help confirm suitability based on symptoms.

Who Should Avoid Canesten Pessary

Do not use Canesten Pessary if:

• you are unsure whether symptoms are thrush
• this is your first episode of vaginal symptoms
• symptoms include strong odour, pelvic pain or bleeding
• you are allergic to clotrimazole

Medical advice should be sought if symptoms are atypical.

How to Use Canesten Pessary

The pessary is inserted high into the vagina, usually at bedtime using the supplied applicator. This allows the medicine to work overnight while lying down.

Hands should be washed before and after use. The pessary should be used exactly as directed.

Safety, Warnings and Side Effects

Canesten Pessary is generally well tolerated. Mild burning or irritation may occur briefly after insertion. If severe discomfort develops, treatment should be stopped and advice sought.

Avoid sexual intercourse during treatment unless advised, as the medicine may weaken latex condoms or diaphragms.

When to Seek Medical Advice

Speak to a GP or pharmacist if:

• symptoms do not improve within 7 days
• thrush keeps recurring
• symptoms worsen
• you are unsure about the diagnosis

Further investigation may be needed.

Use in Pregnancy and Breastfeeding

Canesten Pessary is commonly used during pregnancy on professional advice. Applicators are often avoided in pregnancy, and insertion may be done by hand instead.

Breastfeeding use should also be discussed with a healthcare professional.

How Canesten Pessary Compares to Other Thrush Treatments

Pessary vs oral capsule

Oral fluconazole treats thrush systemically, while pessaries treat infection locally. Choice depends on preference, pregnancy status and symptom pattern.

Pessary vs external creams

Pessaries treat internal infection. External creams relieve itching and soreness and are often used alongside internal treatment.

Canesten Pessary Summary

Canesten Pessary provides effective internal treatment for vaginal thrush by targeting yeast infection at its source. When used correctly and combined with appropriate hygiene measures, it helps clear infection and relieve symptoms.

Persistent, recurrent or unusual vaginal symptoms should always be assessed by a healthcare professional.
