Hello! Thank you for asking HCM! I understand your concern! Answer: The treatment of onychomycosis (nail fungus) depends on the clinical type, the number of affected nails, and the severity of it. Topical treatments alone are generally unable to cure onychomycosis because of insufficient nail plate penetration. The best solution is a combination of systemic and topical treatment because increases the cure rate. But the rate of recurrence is high. Itraconazole tablet, is a good choice. Trosyd cream is tioconazole,so you can find another medicine with the same component but with another commercial name. Hope my answer was helpful!
