Tecnu. Best stuff I ever bought. If you can't find it at your pharmacy, then it may be that you need to ask your pharmacist for it. I had a terrible case of deadly nightshade rash years ago and my skin actually bled. Nothing worked, even cortisone shots. Someone told me about Tecnu and it saved me. It stops the itching immediately and starts to dry up the rash at once. It's great stuff. You'll never use calamine lotion again.
