Hi Doctor I Have Been Using Betnovate N For Almost

Hi Doctor
I have been using Betnovate N for almost 3 yrs now. It started with a Doctor prescribing me Betnovate N for skin rashes I had and after that whenever I stopped rashes and the itch came back and forced me to use Betnovate N again.
Now if I try to stop its use, after 3-4 days my face starts getting itchy and red.
please give me a remedy for this.

Thanks
