My wife is undergoing lymphnode TB treatment since Aug 2009 & is now 6 month pregnant , she is having Oxfloxacin 400 mg , INH 300 mg , Ethambuntal 800 mg each 1 tablet per day . Is this drugs going to have any side effects on the foetus. Please let me know
HI, I understand your concern.  Both High doses of Oxacillin, INH & Ethambutal are placed in category c for their use in pregnancy. Though there are no sufficient evidences about their teratogenicity, they are to be used with precautions in pregnancy when the benefits over weigh the side effects & they are essential for control of Tuberculosis in pregnant woman.  The doses offered to you are in normal range. & I feel you should believe your treating doctor & continue taking it as per the advice, while regular pregnancy check-ups are done.  Thanks.
