According to the South African National Tuberculosis Association, TB patients can develop MDRTB if they stop taking their medication too soon or if they take it erratically.
Menurut Asosiasi Tuberkulosis Nasional Afrika Selatan, pasien TB dapat memperkembangkan MDRTB jika mereka berhenti meminum obat terlalu dini atau jika mereka meminumnya secara tidak teratur.
