Stopped taking Accutane. How long before it will be out of my system?

I started taking accutane a month ago and I got sick the first week for two days and so it continued for a month I was never sick before accutane. I stopped taking it yesterday because I got swollen eyes, chronic headache, joint pain and back pain that goes with a burning throat and ears that never stops I can't eat or sleep. I took scedule 5 pain medication to numb the pain but it only worked for the back pain and headache. How long before accutane will be out of my system?
