I am a 27 yr old female. Single mom of two (5 yrs and a 6mo old) I have been told that I have latent tb. And that I should take either isoniazid or rifampin. My concern is my liver and risk of irreversible damage. I'm also concerned if I would be able to still work (I work with food in a hospital) and take care of my kids. I want to be there for them. But I'm honestly scared. What's your advice?
