i started Zenetane (isotretinoin) 40mg 6 days ago. So far, I have noticed dryness and itchiness. I know it's only been about a week, however I was wondering when the side effects get really bad, and will they last the whole course of treatment? I am a stocker at a huge corporation, so I work with a blade and I'm always lifting and on my feet. Will this eventually affect my job? I don't want to lose my job because of the side effects. Thanks!
