I'm really worried about my TB treatment. My first doctor prescribed AKT4, but I found out it might be less than what's needed for my weight, which is 67kg. So I talked to another pulmonologist who recommended I switch to DOTS and do the full 6-month course. I've already taken AKT4 for a month before switching. I'm just concerneddid the switch affect my treatment at all? Should I be tested for multi-drug resistant TB?
