Symptoms of Rheumatoid Arthritis

GENERIC NAME: phenylbutazone

BRAND NAME: Butazolidine

DRUG CLASS AND MECHANISM: Phenylbutazone has been removed from the United States market due to the availability of newer drugs with less adverse effects. 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 of NSAIDs for any given condition. However, because of a unique risk of bone marrow suppression (causing dangerously low white blood counts), phenylbutazone is generally reserved only for short-term use in selected patients.

PRESCRIBED FOR: Phenylbutazone is used for the treatment of inflammation and pain that results from rheumatoid arthritis, ankylosing spondylitis, gouty arthritis, and osteoarthritis.

SIDE EFFECTS: Most patients benefit from NSAIDs with little side effects. However, serious side effects can occur, and generally tend to be dose related. Phenylbutazone is not a commonly used NSAID because of a unique potential for severe bone marrow toxicity, which results in dangerously low white blood cell counts. Therefore, it is often desirable to use the lowest effective dose to minimize side effects. The most common side effects of phenylbutazone involve the gastrointestinal system.
