What is clotrimazole 1% cream?
Clotrimazole 1% cream is a white topical cream containing clotrimazole 10 mg per gram (1% w/w) as the active ingredient. Clotrimazole belongs to a class of medicines called imidazole antifungals and acts against the fungi responsible for a range of skin infections.
In the context of genital thrush, clotrimazole 1% cream is used to relieve external symptoms affecting the skin of the vulva or the penis. It is a cutaneous (skin) preparation and is not suitable for insertion into the vagina. Internal vaginal thrush requires a separate intravaginal treatment such as a pessary or internal cream.
Available pack sizes include 20 g and 50 g tubes. Not all pack sizes may be available. The cream contains cetostearyl alcohol and benzyl alcohol as excipients, which are noted in the PIL as ingredients that may cause local skin reactions in some people.
Good to know:Clotrimazole 1% cream treats external symptoms on the skin surface only. If you also have internal vaginal symptoms such as internal itching or abnormal discharge, a vaginal pessary or internal antifungal treatment may also be needed. A prescriber or pharmacist can advise on the most appropriate combination.
External thrush symptoms: What clotrimazole cream can help with
External genital thrush can cause itching, redness, soreness, and irritation on the skin of the vulva or penis. These symptoms are caused by a Candida yeast overgrowth on the skin surface, rather than inside the vagina, and respond to topical antifungal treatment applied to the affected area.
Clotrimazole 1% cream is licensed for the treatment of candidal skin infections, including those affecting the genital area. When applied as directed to clean, dry skin, it can relieve the external symptoms associated with thrush.
Thrush is not a sexually transmitted infection. It can affect people regardless of sexual activity.
Important: Seek assessment from your GP or a sexual health clinic before using this product if any of the following apply: this is your first time experiencing these symptoms; you have had more than two episodes in the last six months; you or your partner have had an STI; you are under 16 or over 60; you are pregnant or breastfeeding; or you experience unusual discharge, bleeding outside your normal period, sores, blisters, fever, pelvic pain or pain when urinating. These symptoms may indicate a condition requiring a different treatment.
How clotrimazole works
Clotrimazole works by disrupting the cell membrane of the Candida fungus. It interferes with the production of ergosterol, a component essential to fungal cell membrane integrity, causing the membrane to break down and the fungal cell to die. Applied to the surface of the skin, clotrimazole acts locally at the site of infection.
Clotrimazole 1% cream does not penetrate to internal tissues. It is effective at treating fungal infections on the skin surface but cannot treat an infection inside the vagina. Symptom relief may begin within a few days of starting treatment, but the full course should always be completed as directed in the PIL.
How to use clotrimazole 1% cream
The following guidance is based on the current UK patient information leaflet and SmPC for Canesten Cream (Bayer plc, medicines.org.uk, last revised 2024). Always read the PIL supplied with your specific product before use, as instructions may vary between manufacturers.
Preparation
- Wash your hands thoroughly before applying the cream.
- Clean the affected area gently and allow it to dry completely before application.
Application
- Apply a thin layer of cream to the affected skin and rub in gently.
- A strip of cream approximately half a centimetre long is sufficient to cover an area roughly the size of the hand.
- Apply two to three times daily as directed in the PIL.
- Wash your hands thoroughly after each application.
Duration
For candidal skin infections, the PIL advises that treatment should be continued for at least two weeks. Continue for as long as directed in your PIL, even if symptoms improve before the course is complete.
Important: Do not apply clotrimazole 1% cream inside the vagina, near the eyes, or inside the mouth. It is for external skin use only. Do not use to treat nail or scalp infections.
- Fire safety note: The PIL for Canesten Cream includes the following warning: do not smoke or go near naked flames during use. Fabric including clothing and bedding that has been in contact with this product burns more easily and is a serious fire hazard.
- Missed applications: If you forget to apply the cream, apply it as soon as you remember and then continue as normal. Do not apply a double amount to make up for a missed application.
- If symptoms do not improve: If symptoms have not improved within the timeframe specified in your PIL, or if they worsen at any point, stop using the cream and contact your GP or prescriber.
Who should seek assessment before using this product
Clotrimazole 1% cream is not appropriate for everyone without prior medical guidance. Seek assessment before use if any of the following apply.
- First episode: If this is the first time you have had these symptoms, a clinical assessment is recommended to confirm the cause before starting treatment.
- Recurrent symptoms: More than two episodes in the past six months requires clinical review rather than repeated self-treatment.
- Pregnancy and breastfeeding: Speak to your GP or midwife before using any antifungal treatment during pregnancy or while breastfeeding.
- Age: Seek medical advice before use in children and in adults over 60.
- Diabetes or weakened immune system: Fungal infections may be more persistent in these groups and may require medical assessment and management.
- Penile symptoms with discharge: Penile discharge alongside itching or redness may indicate a condition other than thrush, including an STI, and requires clinical assessment.
- Allergies: Do not use if you are allergic to clotrimazole, cetostearyl alcohol, benzyl alcohol, or any other ingredient listed in the PIL supplied with your product.
- Tacrolimus or sirolimus: An interaction between clotrimazole and tacrolimus or sirolimus has been reported. If you are taking either of these medicines, speak to your doctor before using clotrimazole.
Side effects and precautions
As with all medicines, clotrimazole 1% cream can cause side effects, although not everyone will experience them.
Local skin reactions
The most commonly reported side effects are local reactions at the site of application, including mild burning, stinging, or itching. These are usually temporary. The cream contains cetostearyl alcohol, which may cause local skin reactions such as contact dermatitis in some people. Benzyl alcohol, also present in the cream, may cause allergic reactions and mild local irritation.
Allergic reaction
If you experience signs of a serious allergic reaction, including swelling of the lips, face, throat or tongue, difficulty breathing or swallowing, widespread rash or hives, or dizziness and faintness, stop using the cream immediately and seek emergency medical help. If redness, burning, pain or itching at the application site worsens rather than improves, stop using the product and contact your doctor.
Effect on latex contraception
Clotrimazole cream may damage latex condoms and diaphragms, reducing their reliability as contraception. If applying clotrimazole cream to the genital area, use an alternative method of contraception during treatment. Check the PIL supplied with your specific product for guidance on the recommended duration of this precaution.
Report any suspected side effects to the MHRA via the Yellow Card scheme.
