onychomycosis, toenail
"After a month of taking this for a toenail infection I got a very bad rash over my entire body. It spread so quickly and became painful so I went to the ER where they confirmed it was a reaction to terbinafine. I went to a dermatologist who gave me a shot and put me on prednisone for 30 days and gave me some corticosteroid cream. After three weeks and merciless skin peeling my skin is almost back to normal. I was not able to take it long enough to help my toenails. I cannot recommend this medicine."
