Phenylbutazone Compound Basics
Phenylbutazone is available by prescription only. Phenylbutazone is a non-steroidal anti-inflammatory drug (NSAID) used to treat chronic arthritis and pain following surgery in horses. Phenylbutazone is used to treat pain and inflammation, limping or lameness, decreased activity or exercise, stiffness, decreased movement of joints, and pain following surgery. Like other NSAIDs, phenylbutazone works by inhibiting the formation of prostaglandins.
