Initial symptom improvement during TB therapy is typically seen after how long?

• A. 2 to 3 weeks
• B. 1 to 2 days
• C. 3 to 4 months
• D. 6 to 12 weeks

Answer: (A)

Initial symptom improvement during TB therapy is typically seen after about two to three weeks. This reflects how quickly the drugs reduce the bacterial burden and dampen the inflammatory response driving symptoms. Within this window, fever and systemic symptoms often resolve, energy returns, and weight or appetite can improve. Cough and sputum may begin to lessen as airway inflammation decreases, though some symptoms may take longer to resolve. Radiographic changes, on the other hand, lag behind clinical improvement and aren’t relied upon to judge early response. If there’s no improvement by two to three weeks, it’s important to reassess adherence, drug absorption or interactions, and the possibility of drug resistance or a different diagnosis.
