What it is used for
- Athlete's foot
- Ringworm
- Jock itch
- Vaginal and external genital thrush (yeast infection)
- Fungal skin infections and some cases of nappy rash with fungal involvement
How it works
Clotrimazole damages the cell membrane of fungi and yeasts, stopping them from growing and clearing the infection. Applied to the affected skin or area, it works locally where the fungal infection is.
How it is taken
Comes as creams, sprays, solutions, and vaginal preparations (pessaries/internal creams), often available over the counter. Skin products are applied to the affected area, and vaginal products are inserted as directed. Wash and dry the area first, wash your hands after applying, and continue the full course even after symptoms ease to prevent return. Use it exactly as your doctor, pharmacist or the label directs.
No doses here on purpose. The right strength and schedule depend on you — only a doctor or pharmacist should set them. Always follow your prescription and the label.
Common side effects
- Mild burning, stinging or itching at the site
- Redness or peeling skin
- Mild irritation (including local irritation with vaginal products)
Serious effects — get help
- Signs of a severe allergic reaction such as facial swelling, widespread rash, blistering or difficulty breathing
- Severe local irritation, swelling or worsening rash
- No improvement or worsening of the infection despite treatment
If a reaction is severe — for example trouble breathing, swelling of the face or throat, or collapse — go to the nearest emergency room now or call your local emergency number. Do not wait for an online consultation.
Interactions to watch
- Other skin products on the same area (ask a pharmacist)
- Latex condoms and diaphragms can be weakened by some vaginal antifungal products (use extra precautions)
Who should take care
- Tell your clinician if you are pregnant or breastfeeding before using vaginal products
- See a clinician for a first-time genital infection or recurrent thrush
- Complete the full course to prevent the infection returning
- Avoid the eyes; for external skin and labelled areas only
- See a clinician if symptoms do not improve in the expected time
