The answer to this question depends on the severity or degree of athlete’s foot progression. Normally, infections from this type of fungus can range from mild to severe. Although in all cases a positive outcome can be expected, only the milder infections are eliminated within a period of 2 to 3 weeks. Topical medications or oral antifungal drugs should be maintained for the prescribed period, with the aim of minimizing relapses or recurrences.
Sometimes athlete’s foot fungal infections are not easy to eradicate, even if strong antifungal or antimicrobial drugs are being used, not just simple home remedies. In these cases, treatment must last longer, up to approximately 6 weeks. It is necessary to continue with the treatment for a longer period, even if the fungus has apparently disappeared. This long-term treatment with antifungal medications, even beyond the time when the fungi have disappeared from sight, is necessary to prevent athlete’s foot infections from returning in the most severe cases.
To reduce the treatment time to the shortest possible period, prophylactic measures must be taken, such as keeping feet clean and dry, wearing socks to prevent the fungus from being absorbed into shoes, avoiding keeping feet in humid environments for too long, avoiding contact with places where you suspect the infection is present, among others.
