Terbinafine
tinea corporis
"I was prescribed Terbinafine for a Tinea Versicolor rash across my back and shoulders.  It wasn't very noticeable, but it irritated me in a cosmetic sense.  My doctor put me on a two month Terbinafine plan.  I have taken the medicine once a day orally for about three weeks.  As soon as I started taking it, I felt itchy all the time and urinated more than usual.  Then one Monday morning, I woke up covered in hot, itchy hives everywhere.  It's been three days now, the hives are still there, my upper and lower eyelids are swollen and my hands and feet are swollen to the point of pain.  I'd imagine I'm allergic."
