Which statement about antitubercular therapy is accurate?

• A. TB treatment has no side effects
• B. TB cannot be cured with medications
• C. TB is always resistant to drugs
• D. TB can be cured by antitubercular drugs

Answer: (D)

Treating TB with a combination of antitubercular drugs can cure the infection when taken as prescribed and completed. This works because Mycobacterium tuberculosis is susceptible to a coordinated drug regimen that, over time, reduces and eliminates the bacterial load. Using multiple drugs together is essential to prevent the bacteria from developing resistance, which is why treatment relies on a defined, typically several-month course (often starting with a four-drug intensive phase followed by a continuation phase). Adherence is crucial, and programs that supervise therapy help ensure patients finish the course, leading to high cure rates. Keep in mind that these drugs can have side effects, so patients are monitored for hepatotoxicity, neuropathy, and other adverse effects, which is why supervision and regular checkups are part of successful therapy. The statement that TB cannot be cured with medications is incorrect, as drug-susceptible TB is curable with the right regimen. Drug resistance is not universal; some cases involve resistant strains, but that doesn’t negate the fact that appropriately treated TB can be cured in many patients.
