What is the first treatment for tuberculosis?

Tuberculosis is an infection that can affect the lungs or other parts of the body. Treatment normally uses more than one antibiotic because the bacteria can be difficult to eliminate and may become resistant if medicines are used incorrectly. The exact medicines and length of treatment depend on the infection site, test results, previous treatment, and your overall health.

Assessment may include a tuberculosis screening test, samples for laboratory testing, and a chest X-ray when lung involvement is suspected. A positive screening result does not by itself show whether active disease is present, so your clinician interprets it alongside symptoms and other findings.

Take each prescribed antibiotic exactly as directed and do not stop when you begin to feel better. Tell the treatment team about every medicine, supplement, pregnancy, liver problem, or previous antibiotic reaction. Keep appointments so symptoms, side effects, and test results can be reviewed.

Follow infection-control advice carefully if pulmonary tuberculosis is suspected. Ask how to reduce close-contact exposure at home and when work, school, or travel restrictions can be lifted. Do not share leftover antibiotics or use someone else's treatment.

Seek urgent medical help for severe breathing difficulty, coughing blood, confusion, fainting, chest pain, or rapidly worsening illness. Contact the treatment team promptly for yellowing of the skin or eyes, severe vomiting, a widespread rash, or unusual vision changes after starting medicine, because these may signal a serious reaction.

Ask which tests confirm active disease, how the antibiotic combination should be taken, which side effects need immediate advice, whether household contacts need screening, and how follow-up will check your response.
