Itraconazole
"I took one course of itraconazole (pulse therapy, 400mg/day during 1 week), after being unsuccessfully treated for onychomycosis of my 5th foot nail (I had it for years). So, since terbinafine didn't help, I decided to use this one, as my doctor advised. Now I have my new nail growing healthy,
so my decision is to continue the treatment with this drug."
