Welcome To HealthcareMagic forum,
The best treatment for t.cruris is to take a fungicidal antifungal tablet. like terbinafine
(250mg) ONCE DAILY...for a month ..Or you can also take tab fluconazole
(150mg) one tab once a wk for 4 wks...use a anti fungal powder in day time and a anti fungal cream at night...this would completely cure your problem.
