Synopsis

Currently advocated regimens for latent tuberculosis infection (LTBI) typically involve treatment durations that provide 60-90% efficacy in reducing progression to active tuberculosis, though the specific duration is not stated here (commonly 3-9 months depending on regimen). (6354243) A full course of LTBI treatment is often defined as 270 doses, which corresponds to approximately 9 months of daily isoniazid therapy. (5451105) Completion of the recommended LTBI treatment course reduces the risk of progression to active tuberculosis by 80% compared to those who do not complete treatment. (5451105)
