Abstract:
A 73-year-old woman, with tuberculosis of the large intestine, developed nausea as a side effect of the antituberculosis drugs. The nausea was treated with metoclopramide. Subsequently she developed severe medication-induced parkinsonism. As her symptoms initially mimicked a depressive disorder, drug-induced parkinsonism was only considered at a later stage. Due to drug-induced impaired function of the liver and kidney the patient had received a toxic dose of metoclopramide. Treatment with biperiden and withdrawal of the metoclopramide resulted in a reduction of the complaints within 3 months, after which the anti-tuberculosis medication could be reintroduced. Adjusting the dose of metoclopramide could possibly have prevented this severe side effect.
