FAQ
Frequently Asked Questions
Ethionamide is a prescription antibiotic medication used specifically to treat tuberculosis (TB), particularly when the TB bacteria are resistant to first-line drugs.
No, it is a specialized, second-line drug. It is used only when standard, first-line TB treatments are ineffective or cannot be used due to side effects or drug resistance.
Common side effects can include significant gastrointestinal issues (nausea, vomiting, loss of appetite), metallic taste, and potential liver problems. It requires careful medical supervision.
Almost certainly not. It is a highly technical medical term. You would encounter it only in specialized medical English courses or contexts related to healthcare, pharmacy, or global public health.
