Answer 4 Administer isoniazid, rifampin, and ethambutol for 9 months. Pregnant women who are suspected of having TB must be treated without delay, irrespective of the stage of the pregnancy. The preferred treatment regimen is isoniazid, rifampin, and ethambutol administered for 9 months. If the likelihood of isoniazid resistance is low (less than 4% in the community), then ethambutol may be excluded. Streptomycin can cause ototoxicity and therefore should be avoided. The teratogenic potential of pyrazinamide is unknown; therefore, it is not recommended for use during pregnancy.1 REFERENCE 1. Core curriculum on tuberculosis. 4th ed.
