My husband has a skin condition, dermatitis of unknown origin. He was prescribed prednisone and an antibiotic for one week and 100 mg of cyclosporine for a month . He finished the prednisone and the antibiotic and it cleared it up almost 100%. Since he stopped taking it it is now starting to get bad again. The itching is almost unbearable. He wants to stop taking the cyclosporine. Can he?
