Thanks for your question on Health Care Magic.
I can understand your concern.
Practically, there is no harm in getting pregnant while on anti tubercular drugs.
Amongst anti tubercular drugs, only
streptomycin and
levofloxacin are teratogenic and can harm developing fetus.
So if currently you are taking any of these drugs then you should first stop these drugs and then you can conceive.
Maintaining good immunity and nutrition is also important while conceiving with anti tubercular drugs.
So also take
multivitamin tablet containing
folic acid,
vitamin b12, b6. Also start high protein diet.
So above mentioned precautions should be taken while conceiving with anti tubercular drugs.
Hope I have solved your query.
I will be happy to help you further.
Wish you good health. Thanks.
