About DOTs

National TB treatment guidelines strongly recommend using a patient-centered case management approach - including directly observed therapy (DOT) - when treating persons with active TB disease. DOT is especially critical for patients with drug-resistant TB, HIV-infected patients, and those on intermittent treatment regimens (i.e., 2 or 3 times weekly). DOT means that a trained health care worker or other designated individual (excluding a family member) provides the prescribed TB drugs and watches the patient swallow every dose.
