I've had scabies for the past 6 months, I've tried the cream being with L (not too sure on the actual name) but had an allergic reaction to it so tried the derbac lotion 4 times now and it still hasn't gone. I rang my doctors but they said there's nothing else they can give me. Is there literally nothing else I can try? My skin is awful from all the scratching, anti itch creams don't seem to be working!
