My mother is taking pulmonary tb medicine from past six months. Only infections noticed but no cavities as such when detected. She is better now but read few blogs where it is mentioned that tb medicines cause lung damage and also cause secondary infections later. Is this true? What precaution to take? Pls advice.

Wash your hands often,avoid smoking, stay upto date on covid vaccines,avoid second hand smoke and also avoid air pollution.Also patient is advised infuenza vaccinaion.
