antituberculor drug has its side effects.
first to be witnessed are
1.bad taste in mouth and gastric upsets that will subside in a months time
2.loss of apetite is associated with it , apetite returns when the tubercular infection
starts to subside that is in 1-2 months time
4.long run ,side effects include mild to moderate loss in vision and hearing ...that resumes to near normal after few months of stopping the medication
so dont worry and just keep in mind that the medications are to be taken regularly without a single brake
hope this helps
