You can get cortisone cream from the chemist without a prescription, but it's not a great idea to use much of it as it remains in the body. I used it out of necessity while I was pregnant with Christine, as my skin itched so much I was tearing welts in myself as I slept. No harm came of it, but it is something to be aware of.
Only use it as necessary, try the sorbolene first and see if you get good results from that.
