Suggest Treatment For Facial Zits And Itching

Hi. I have been using betnovate cream on my face for years now. I wash my face before going to sleep every night and apply it on my face. I tried to stop using it but can't cos my skin gets very itchy and red and small zits start appearing on forehead, cheeks and chin if i do not apply it on my face for a day even. I have a very oily skin and i started using betnovate cream without any consultation with a doctor. Therefore i am now completely dependent on betnovate in order to avoid zits and itchiness. What should i do? I want to discontinue using betnovate cream..please suggest what should i do?
