How it works
Phenylbutazone is a nonsteroidal anti-inflammatory drug (NSAID) effective in treating fever, pain, and inflammation in the body. As a group, NSAIDs are non-narcotic relievers of mild to moderate pain of many causes, including injury, menstrual cramps, arthritis and other musculoskeletal conditions. Since the response to different NSAIDs varies from patient to patient, it is not unusual for a doctor to try a variety NSAIDs for any given condition. However, because of an unique risk of bone marrow suppression (causing dangerously low white blood counts), phenylbutazone is generally reserved only for short-term use in selected patients.
