What is the next set of drugs after treating ptb infection with 4d drug combination after 2 months? Im asking this because i forgot the treatment rogram i went through 14 yrs ago when was infected by tb. This is for me to answer doctors asking for my program whenever they see my scars in the xray to know if i really went medication or not. I can no longer see my doctor since he migrated to anothr country more than 10 yrs ago. Thank you
