Tanning and prescription topical acne medication?

So my questions a little different than most tanning and acne medication questions. I already know from first hand experience what will happen if I tan in a tanning bed while using my acne medication (Ziana). I burn the h*** up!!! So what I'm needing to know is can I just wait till this burn goes away and get back in the tanning bed burn a little bit less and keep doing this until I no longer burn?? Will that ever happen? Because I honestly have my doubts... So my other option is just quit using the medication. Tanning usually clears up my acne quiet reasonably anyways. Anyways, if I just stop using it how long will it take before tanning will not cause me to burn any longer? Right away? Or does it take a while for your skin to go back to normal?? Thanks to any and all helpful answer! (:
