TB preventive therapy

TB preventive therapy involves taking medication to reduce the risk of developing active tuberculosis (TB) if you've been exposed or have a latent infection. Latent TB means the bacteria are in your body but not causing illness or symptoms. The therapy helps eliminate these hidden bacteria before they cause illness, especially for people at higher risk, such as those with immune system issues or recent exposure. Usually, it involves a course of antibiotics over several months. This approach is a key step in preventing the spread and serious health problems caused by TB.
