All patients in a defined group should receive the same regimen. Different groups might receive a different regimen. For example:
- All patients with a strain susceptible to first-line drugs should receive the same standard treatment regimen for 6 months, (may be extended up to 12 months, depending on the site of involvement).
- Patients who fail to respond to the first-line anti-TB drugs, will be tested with Gene Xpert and whenever possible both 1st line and 2nd line DST (LPA, Liquid culture & DST) will be done and patient will be managed as per DR TB guidelines.
