From the Guidelines
To treat a fungal foot rash, apply clotrimazole cream to the affected area twice weekly for 4 weeks, as this regimen has been shown to be effective in managing similar fungal infections, such as T cruris 1. When using clotrimazole cream, it is essential to follow proper application and hygiene techniques to maximize its effectiveness and prevent the spread of the infection.
- Before application, wash and thoroughly dry the affected area, as fungi thrive in moist environments.
- Apply a thin layer of cream and gently massage it into the skin until absorbed.
- Wash your hands before and after application to prevent spreading the infection.
- For best results, wear clean cotton socks and well-ventilated shoes during treatment, and avoid walking barefoot in public areas like pools or showers. Clotrimazole works by disrupting the fungal cell membrane, preventing growth and reproduction of the fungus.
- Most people see improvement within a few days, but completing the full treatment course is essential to prevent recurrence.
- If symptoms worsen or don't improve after two weeks, consult a healthcare provider as you may need a stronger prescription antifungal medication, such as terbinafine or oral itraconazole, which have been shown to be effective in treating fungal infections 1.

From the Research
Treatment for Fungal Foot Rash using Clotrimazole Cream
- Clotrimazole is an antifungal agent effective in treating dermatophytosis, cutaneous candidiasis, and tinea vesicolor 2.
- A controlled double-blind clinical trial compared topical clotrimazole with its vehicle in treating 66 patients with dermatophytic infections of the skin of the feet, and clotrimazole proved to be effective in treating tinea pedis of both the interdigital and the plantar hyperkeratotic types 2.
- However, a study comparing terbinafine and clotrimazole in treating tinea pedis found that terbinafine was more effective than clotrimazole in terms of mycological cure and effective treatment 3.
Comparison with Other Treatments
- A study comparing oral terbinafine with clotrimazole cream in interdigital tinea pedis found that oral terbinafine was as effective and well-tolerated as clotrimazole cream 4.
- Another study found that terbinafine was more effective than griseofulvin, and terbinafine and itraconazole were more effective than no treatment in treating fungal infections of the skin of the foot 5.
Mechanism of Action
- Clotrimazole is a fungistatic agent, limiting fungal growth but depending on epidermal turnover to shed the still-living fungus from the skin surface 6.
- Fungicidal drugs like terbinafine are often preferred over fungistatic drugs like clotrimazole for treatment of dermatophytic fungal infections, as they can kill the fungal organisms and have higher cure rates with shorter treatment times 6.
