Hi,welcome to healthcare magic
Although the TB medication
can cross the placenta barrier, some of the drugs used in TB are thought to have minimal effect on the fetus.
The drugs that cannot be used because of potential harmful effects include:streptomycin
,amikacin,flouroquinolones and capreomycin which are usually the second line drugs.
You partner should do a pregnancy
test to determine if she is pregnant and if positive visit the doctor for an assessment.
I hope this helps
