During the TB continuation phase, the dosing frequency is described as which?

• A. Daily
• B. Intermittently
• C. Weekly
• D. Monthly

Answer: (B)

Continuation phase dosing in TB treatment is typically intermittent rather than daily. After the initial intensive phase, the regimen is continued with fewer doses per week—often three times weekly—in many standard regimens. This intermittent approach keeps drug exposure above the needed level to prevent relapse and resistance while reducing the burden of taking medicine every day and making supervision easier. Daily continuation exists in some regimens, but the conventional continuation-phase schedule is described as intermittent (e.g., three times per week). Weekly or monthly dosing would generally be too infrequent to maintain effective drug levels throughout the continuation period.
