Single-Dose Oral Treatment for Vaginal Thrush

Fluconazole Thrush Capsule 150 mg Overview

Fluconazole Thrush Capsule 150 mg is an oral antifungal medicine used to treat vaginal thrush (vulvovaginal candidiasis). It contains fluconazole, which works systemically to clear the fungal infection from within the body.

In the UK, the 150 mg capsule is a pharmacy medicine (P) supplied for uncomplicated vaginal thrush in adults. It is taken as a single dose, offering a convenient alternative to topical antifungal creams or pessaries.

Understanding Vaginal Thrush

What causes thrush?

Vaginal thrush is most commonly caused by an overgrowth of Candida albicans, a yeast that normally lives harmlessly in the body. Changes in the vaginal environment can allow Candida to multiply, leading to symptoms.

Triggers may include antibiotic use, hormonal changes, stress, tight clothing, diabetes, or immune changes.

Common symptoms

Thrush typically causes intense itching, soreness, redness, and swelling around the vulva, along with a thick, white discharge often described as “cottage-cheese like”. Pain during sex or stinging on urination can also occur.

What Is Fluconazole 150 mg?

Fluconazole 150 mg is a systemic antifungal from the triazole class. Unlike topical treatments that act locally, fluconazole is absorbed into the bloodstream and treats the infection throughout the body.

It is particularly useful for people who:

• prefer oral treatment
• find topical products messy or inconvenient
• have not responded fully to creams or pessaries

How Does Fluconazole Work?

Antifungal mechanism

Fluconazole works by inhibiting ergosterol synthesis, an essential component of the fungal cell membrane. Without ergosterol, the fungal cell membrane becomes damaged, preventing the fungus from growing and allowing the infection to clear.

How quickly it works

Symptoms often begin to improve within 24–48 hours, though complete relief may take several days as inflammation settles and tissue heals.

What Fluconazole Treats — and What It Does Not

What it treats

Fluconazole 150 mg is used to treat:

• uncomplicated vaginal thrush
• thrush symptoms such as itching, soreness, and discharge

What it does not treat

Fluconazole does not:

• treat bacterial vaginosis
• treat sexually transmitted infections
• prevent future episodes of thrush
• provide instant symptom relief

If symptoms are unusual or severe, further assessment is required.

Who Is Fluconazole Thrush Capsule For?

Fluconazole may be suitable for:

• adult women aged 18 to 60 years
• those with previously diagnosed thrush
• uncomplicated, typical symptoms

A pharmacist will usually confirm suitability before supply.

Who Should Avoid Fluconazole

Fluconazole is not suitable if:

• you are allergic to fluconazole or other azole antifungals
• you are pregnant or trying to conceive
• you have liver disease
• you have kidney problems (unless advised)
• this is your first episode of thrush
• symptoms are recurrent (more than twice in 6 months)

In these cases, medical advice is recommended.

How to Take Fluconazole Thrush Capsule

Dosage

• Take one 150 mg capsule as a single dose
• Swallow with water
• Can be taken with or without food

Important usage advice

• Do not take more than one capsule unless advised
• Avoid alcohol if you feel unwell
• Continue to monitor symptoms for improvement

Safety, Warnings and Side Effects

Common side effects

Some people may experience:

• headache
• nausea
• stomach discomfort
• mild skin rash

These effects are usually short-lived.

Liver considerations

Fluconazole is processed by the liver. Rarely, it can affect liver function, particularly in people with existing liver conditions or those taking certain medicines.

When to Seek Medical Advice

Speak to a GP or pharmacist if:

• symptoms do not improve within 7 days
• symptoms worsen or change
• you experience severe abdominal pain or jaundice
• thrush keeps returning
• discharge has a strong odour or unusual colour

These may indicate a different diagnosis or the need for alternative treatment.

Use in Pregnancy and Breastfeeding

Fluconazole 150 mg is not recommended during pregnancy. Topical antifungal treatments are usually preferred. Breastfeeding women should seek medical advice before use.

How Fluconazole Compares to Other Thrush Treatments

Fluconazole vs thrush creams and pessaries

Topical treatments act locally and are often first-line, especially in pregnancy. Fluconazole offers a convenient oral option for those who prefer a single capsule.

Fluconazole vs repeated topical use

Oral treatment may be helpful where topical treatments have not been effective or tolerated, provided there are no contraindications.

Supporting Vaginal Health

To help reduce the risk of thrush:

• avoid perfumed soaps and washes
• wear breathable cotton underwear
• avoid tight clothing
• change out of damp clothing promptly

Small lifestyle adjustments can help prevent recurrence.
