Abstract
At the University Centre for Chronic Diseases Dekkerswald, a tertiary tuberculosis (TB) referral hospital in The Netherlands, therapeutic drug monitoring (TDM) is used in patients in case of relapse TB, when there is delayed response to TB treatment, and when abnormal TB drug concentrations are suspected for other reasons. In this article, a case series is presented to illustrate the value of individualized TB drug dosing in four patients with low TB drug concentrations. Increased doses of the TB drugs, especially of rifampicin, resulted in adequate peak plasma concentrations and improved clinical response to treatment in these patients, while no adverse events occurred.
