From the Guidelines
Prescription antifungal creams, such as clotrimazole 1%, miconazole 2%, or terbinafine 1%, are the most effective treatment for athlete's foot, and should be applied twice daily for 2-4 weeks. When treating athlete's foot, it is essential to consider the causative organisms, which are often T rubrum and T mentagrophytes, as noted in a study on infectious diseases associated with organized sports 1. To effectively manage the infection, apply the cream to the affected areas, typically the fissures and scaling between toes, after washing and thoroughly drying your feet. Some key points to keep in mind when using these medications include:
- Keeping your feet clean and dry
- Wearing breathable footwear
- Changing socks daily
- Avoiding walking barefoot in public areas These antifungal creams work by disrupting the fungal cell membrane or inhibiting essential enzymes needed for fungal growth. If symptoms persist after 4 weeks of treatment or worsen at any point, it is crucial to consult your healthcare provider, as you may need oral antifungal medication for more extensive infection.
