Hi Doctor, I Was Diagnozed Last July 2015 With Minimal

hi doctor, I was diagnozed last july 2015 with minimal ptb and was given FIXCOM3 for 3 mos...and my medication ends today oct 13, 2015... I go back to my doctor and he said that I will take RIMACTAZID 450 mg for another 3 mos...but he never tells me to take another x-ray? would it be ok to take this RIMACTAZID? and how long is the medication in my case?bec my doctor tell me that after taking the FIXCOM3 he said that I'll be going back to him to give me a certification so that I can look for my job?thanks
