I'm trying to understand my current TB treatment and could use some guidance. I've been dealing with abdomen TB and finished the first two months on Akurit 4 with four tablets a day. Now I'm on Combutol 1 gm and R Cinex 600 mg, along with a multi-vitamin. Initially, I started at 65 kg and now I'm at 68 kg, and I've noticed my appetite has increased, too. The doctor mentioned something about changing to a regimen with a full six months of rifampicin, and I'm a little confused about what that means for relapses and failures. Can you explain how this change might impact my recovery? Also, should I be concerned about the weight gain? I'm 34, by the way.
