From the Guidelines
The recommended treatment for athlete's foot (tinea pedis) is typically an over-the-counter topical antifungal medication such as clotrimazole 1% (Lotrimin), miconazole 2% (Micatin), or terbinafine 1% (Lamisil AT). These medications should be applied to the affected areas twice daily for 1-2 weeks, continuing for at least one week after symptoms resolve to prevent recurrence. According to a study published in Pediatrics 1, T pedis is prevalent in warm, humid environments and affects men more than women, with the predominant causes being T rubrum and T mentagrophytes. Some key points to consider when treating athlete's foot include:
- Keeping feet clean and dry
- Changing socks daily
- Wearing breathable footwear
- Avoiding walking barefoot in public areas For more severe or resistant cases, prescription-strength topical medications like ciclopirox or oral antifungals such as terbinafine 250mg daily for 2 weeks may be necessary. It is essential to note that if the infection doesn't improve after two weeks of treatment, spreads to other body parts, or if you have diabetes or a weakened immune system, consulting a healthcare provider for more specialized treatment is crucial. Antifungal medications work by disrupting the fungal cell membrane or inhibiting ergosterol synthesis, which is essential for fungal cell survival, as noted in the context of treating infectious diseases associated with organized sports and outbreak control 1.
From the FDA Drug Label
DOSAGE AND ADMINISTRATION Sufficient Econazole Nitrate Cream, 1% should be applied to cover affected areas once daily in patients with tinea pedis, tinea cruris, tinea corporis, and tinea versicolor, and twice daily (morning and evening) in patients with cutaneous candidiasis Early relief of symptoms is experienced by the majority of patients and clinical improvement may be seen fairly soon after treatment is begun; however, candidal infections and tinea cruris and corporis should be treated for two weeks and tinea pedis for one month in order to reduce the possibility of recurrence The recommended treatment for athlete's foot (tinea pedis) is to apply Econazole Nitrate Cream, 1% once daily to cover the affected areas for one month to reduce the possibility of recurrence 2.
- Key points:
- Apply cream once daily
- Treat for one month
- Reduce recurrence possibility
- Important consideration: If a patient shows no clinical improvement after the treatment period, the diagnosis should be redetermined 2.
From the Research
Treatment Options for Athlete's Foot
- Topical antifungal agents are a common treatment for athlete's foot, as mentioned in 3.
- Oral griseofulvin may be used for more resistant cases, as stated in 3.
- Terbinafine 1% cream has been shown to be effective in treating athlete's foot, with a significant cure rate compared to placebo, as demonstrated in 4.
- A comparison of terbinafine 1% cream and clotrimazole 1% cream found that terbinafine was more effective in treating tinea pedis, as shown in 5.
Duration and Frequency of Treatment
- Terbinafine 1% cream can be applied twice daily for 1 week, as mentioned in 5.
- A single-dose terbinafine 1% formulation has also been shown to be effective in treating athlete's foot, as demonstrated in 6.
- Oral terbinafine can be taken once daily for 2 weeks to treat moccasin tinea pedis and tinea manuum, as stated in 7.
