Hi got skin itchy and rash for more than 1 month, I tried c- zine, it went away very quick, but it back after 2 days, that s why I visited doctor, she gave me prenisolone 50mg a day for four days, but it did not work. At least it did not work like c zine. I could not sleep since I had it, I woke up at mid night with my skin burning Not sure if you can give me an advice, today I took the last dose and I don t think that I will have it again
