Which method is most effective to ensure compliance with TB medications?

• A. Direct observed therapy
• B. Monthly lab tests
• C. Self-monitoring
• D. Patient education

Answer: (A)

Ensuring adherence to TB treatment is crucial because the regimen is long and doses must be taken consistently to cure the infection and prevent drug resistance. Directly observed therapy addresses common barriers by having a health worker or trained observer watch the patient take each dose, ensuring no doses are missed. This supervision creates accountability, supports timely management of side effects, and helps keep the treatment on track across the full course.

While monthly lab tests help monitor safety and response, they don’t guarantee that medications are swallowed as prescribed. Self-monitoring relies on the patient’s own discipline, which can falter over many months. Patient education improves knowledge and understanding, but without supervision, adherence can still be inconsistent. Therefore, directly observed therapy is the most effective method for ensuring compliance with TB medications.
