[|Human|] Hello doc. Im a 35 y/o housewife taking care of my two nephews dx to have PTB. Is there any medicine that i can take in order to prevent myself from being infected since ive been exposed to them even before they were diagnosed and treatment started?
[|AI|]  HiT hanks for choosing Chat Doctor for your query. Since TB is highly contagious disease, the close contacts of a person with pulmonary (lung) tuberculosis are prone to develop infection because TB spreads by Chat Doctor. Visit the treating doctor for the skin testing like Contour test. You will have to take Isoniazid tablet once daily for 6 months or Isoniazid and Rifampcin once daily for 3 months. This will prevent you from TB infection. This preventive treatment should be given to all family members including the housemaid and servants. I hope your query is being explained.Feedback in this regard is highly appreciated.
