Abstract
Naproxen was used as an antipyretic agent in febrile pediatric cancer patients with evidence of active malignant disease. Sixteen children with leukemia and lymphoma who had fever for more than 72 hours were given naproxen to control fever. Their ages ranged from 16 months to 17 years. There were ten female and six male patients. Their temperature was > 38.3°C and the leukocyte count ranged from 400/μl to 33.3 × 103/μl, with an absolute neutrophil count (ANC) from 0 to 4514/μl. The children had no evidence of infection by clinical or laboratory evaluations. All patients were receiving triple antibiotics when naproxen was started. Fourteen patients responded to naproxen with complete lysis of fever within 6 hours of initiation of treatment. Two patients did not respond to naproxen, but proved to have culture‐positive infections. There were no side effects from the drug. Naproxen is an effective antipyretic in patients with cancer. It may be useful as a means of differentiating fever secondary to active malignant disease from that due to infection.
