Terbinafine
"Fungus on my right pinky finger got really bad. I tried Nystatin and tea tree oil which did not work at all. I went to my doctor and he prescribed me Terbinafine (Lamasil) and I had to take the pills for 42 days which were really gross. I finished it off and my nail grew half way in, only for my infection to come back a week later. The medication worked but the infection came back within 7 days. Upset I have to deal with the painful mess all over again."
