Rimactazid is prescribed in cases of active treatment of tuberculosis when combined with other antibacterial drugs to ensure the effectiveness of treatment and prevent the development of bacterial resistance. It is used as a preventive measure for people who have been exposed to tuberculosis or those who are more susceptible to infection such as immunocompromised patients or individuals living in areas where the infection is highly prevalent.
Rimactazid works to prevent latent tuberculosis, where the microbe can remain dormant in the body for long periods before becoming active.
