How is onychomycosis treated?

Onychomycosis treatment includes daily preventive measures, physical nail trimming, topical antifungal medications, oral antifungal medications, and surgical removal of infected nails. Onychomycosis is caused by dermatophyte infection of the nail plate; fungal invasion leads to nail thickening, discoloration, and structural damage. Consistent, standardized interventions can suppress fungal growth and promote healthy nail regeneration. If symptoms such as perionychial redness, swelling, pus formation, or severe pain occur, prompt medical evaluation and treatment at a hospital are recommended.

1. Daily Prevention: Keep hands and feet clean and dry; wear breathable shoes and socks; wash and sun-dry footwear and socks regularly; avoid sharing slippers or nail clippers with others; prevent nail trauma; minimize cross-contamination and prevent disease spread to other nails.

2. Physical Nail Trimming: Regularly file and trim thickened, brittle infected nails to remove fungus-invaded nail plate tissue. This reduces fungal reservoirs and enhances subsequent drug penetration. Take care not to injure surrounding healthy periungual skin during the procedure.

3. Topical Antifungal Medications: After cleaning and filing the affected nail, apply antifungal agents directly to the lesion to inhibit intra-nail fungal proliferation. Treatment duration is prolonged and must continue until a fully healthy new nail has grown out—do not discontinue prematurely.

4. Oral Antifungal Medications: When multiple nails are involved or topical therapy proves ineffective, systemic antifungal drugs may be prescribed under professional guidance. These agents act systemically to eradicate fungi. During treatment, regular monitoring of relevant physiological parameters is essential; dosage and duration must not be altered without medical supervision.

5. Surgical Removal of Infected Nails: For refractory or severe onychomycosis, surgical avulsion of the diseased nail may be performed to eliminate the completely destroyed nail plate. Postoperatively, proper wound care and concurrent antifungal therapy are required while awaiting gradual replacement by healthy nail growth.

Maintain foot dryness by changing shoes and socks frequently; avoid cutting nails too short to prevent periungual skin injury; monitor nail recovery regularly; and complete the full course of treatment to reduce the risk of onychomycosis recurrence.
