Filgrastim therapy in a child with neutropenia induced by linezolid.

We describe the case of a young child with multidrug-resistant tuberculosis, treated with linezolid. The child developed severe neutropenia after 5 months of treatment. Filgrastim was used, a drug that officially is not indicated for non-cytostatic drug-induced neutropenia. This allowed the fast recovery of the patient's neutrophil-count. However, more experience with the off-label use of filgrastrim is needed in the pediatric population.
