Hello,

Thank you for posting a query.

Look, for tuberculosis, you sister is taking drugs like rifampicin, isoniazid, ethambutol and pyrazinamide. These are very much effective against tuberculosis bacteria.

But, these drugs have some side effects like gastrointestinal disturbances like nausea, vomiting, bloating. Peripheral neuritis, myalgia, orange color urine are all side effects of the drugs you are taking.

So, the condition is not harmful. You do not have to worry. She has to continue the drugs. So, give her ondansetron group of drug for prevention of vomiting. A lansoprazole group of drug should also be considered. It will lower the gastrointestinal problems. She has to take A multivitamin agent .

Consult with her treating doctor for the above mentioned drugs.

Hope this information suffices. Let me know, if you have any more question.

Regards.
