Can you pause with an Isotretinoin treatment a few months with no impact on the outcome?

I have been taking Isotretinoin for approx 2 months and now I have to pause treatment for approx 2-6 months. What I am asking is if the treatment result will be negative if I restart the treatment after this period? Will the body response differently after a restart? Could there be a risk that the body develops resistance if the body has been exposed to medicine at an earlier time, like in my case? Please answer the above questions, preferably by a dermatologist! THANKS!
