About this trial
This study is a two-arm, pragmatic, open-label, randomized clinical trial to determine the efficacy of Therapeutic Drug Monitoring (TDM) in preventing premature discontinuation of Linezolid (LZD) in participants with Rifampicin-resistant tuberculosis (RR-TB). Following the initiation of treatment, participants will be monitored throughout the approximate 6-month duration of RR-TB therapy.

Disqualifiers
