Dexamethasone therapy in patients with brain tumors--a focus on tapering.

Administration of corticosteriods in brain tumor patients requires an understanding of the physiology of the adrenal system and desired patient response. Close attention to other concomitant medications will ensure adequate amounts of all drugs, including dexamethasone. Nurses need to assess patients' tolerance of dexamethasone, discuss these findings with physicians and pharmacists, and educate both patients and family members on doses and tapering schedules tailored to individual patient needs.
