From the Guidelines
The treatment for itchy foot fungus (tinea pedis) typically involves antifungal medications applied directly to the affected areas, with terbinafine being a preferred option due to its high cure rates and low relapse rates, as supported by studies such as 1 and 1. For mild to moderate cases, over-the-counter topical antifungals like clotrimazole (Lotrimin), miconazole (Micatin), or terbinafine (Lamisil AT) should be applied to clean, dry feet twice daily for 1-4 weeks, continuing for at least one week after symptoms resolve to prevent recurrence. Some key points to consider in the treatment of tinea pedis include:
- The importance of keeping feet clean and dry, wearing breathable footwear, changing socks daily, and avoiding walking barefoot in public areas to prevent reinfection, as emphasized in 1.
- The use of prescription-strength topical medications like ciclopirox or oral antifungals such as terbinafine (250mg daily for 2-6 weeks) or itraconazole (200mg daily for 1-2 weeks) for more severe or resistant infections, with terbinafine being preferred due to its superior efficacy and safety profile, as noted in 1.
- The need to consult a healthcare provider if symptoms worsen, include blisters or open sores, or don't improve after two weeks of treatment, as these may indicate a more severe infection or the need for alternative treatments, as suggested in 1. It's also important to note that antifungal medications work by disrupting the fungal cell membrane or inhibiting essential enzymes needed for fungal growth, and that treatment should be tailored to the individual patient's needs and circumstances, taking into account factors such as the severity of the infection, the patient's medical history, and potential drug interactions, as discussed in 1 and 1.

Treatment Options for Itchy Foot Fungus (Tinea Pedis)
The treatment for itchy foot fungus, also known as tinea pedis, can be managed through various methods, including:
- Topical therapy: applying an antifungal cream or ointment to the affected area, as seen in studies 3, 4, 5
- Oral therapy: taking antifungal medications orally, as discussed in studies 6, 7
Topical Treatment
Topical treatment is an accepted and successful method for managing tinea pedis, with cure rates of > or = 80% achievable through the application of an antifungal twice or 3 times a day for 3-4 weeks 3. Terbinafine, a new antifungal, has been shown to give equally good results when applied once or twice daily for 1-2 weeks 3, 4, 5.
Oral Treatment
Oral therapy is usually used for chronic conditions or when topical treatment has failed 7. The effectiveness of oral antifungal agents such as fluconazole, itraconazole, and terbinafine in treating tinea pedis has been reviewed in study 6. Terbinafine has been found to be more effective than griseofulvin, and terbinafine and itraconazole are more effective than no treatment 7.
Comparison of Treatments
Studies have compared the efficacy of terbinafine and clotrimazole in treating tinea pedis, with terbinafine showing superior results 4, 5. A comparison of oral treatments found that terbinafine is more effective than griseofulvin, and terbinafine and itraconazole are more effective than no treatment 7.
Key Findings
- Terbinafine is a highly effective treatment for tinea pedis, with cure rates of up to 93.5% achievable through topical application 4
- Oral terbinafine is effective in treating tinea pedis, with a daily dose of 250 mg for 2 weeks showing good results 6
- Itraconazole and fluconazole are also effective oral treatments for tinea pedis, although the evidence is limited by the small number of studies and poor reporting of trial methods 7
