Can acne relapse after an intensive Accutane treatment?

I was faced with acne in high school and went through a long struggle until I managed to cure myself of pimples and blackheads. I have oily skin and any touch of a hand or a little dust made a pimple/blackhead appear. After a while my entire face was full of large pimples and blackheads due to excess sebum. I took Accutane for 6 months and after four months I had smooth skin. Indeed, I felt a lot of so-called side effects but I got rid of acne. Since then four years have passed, but I think it started to reappear. Is it possible for acne to relapse even after all this time?
