The full course of TB treatment lasts from six months to a year, depending on the individual’s choice. TB applies to a chronic infectious disease caused by Mycobacterium tuberculosis, so the treatment course is relatively longer. The standardized regimen for first-time TB patients is usually 6 months, with the first 2 months as intensive treatment and the last 4 months as consolidation. For patients who have been retreated from TB, the regimen is usually 8 months, divided into two main phases, including the first 3 months of intensive treatment and the last 5 months of consolidation treatment. For drug-resistant TB, the treatment regimen may be longer, taking about 1 year, and in some cases even extending to 1.5 years. If tuberculosis is suspected, it is recommended to consult a doctor, who will formulate a treatment plan and a course of treatment according to the patient’s condition.
