Flunixin is primarily used in veterinary medicine as a non-steroidal anti-inflammatory drug (NSAID) to manage pain, fever, and inflammation in animals. It is commonly administered to livestock, such as cattle, horses, and pigs, to alleviate discomfort associated with conditions like colic, mastitis, and respiratory infections. In cattle, it is often used to reduce inflammation following surgical procedures or to treat endotoxemia. Flunixin is also effective in managing musculoskeletal pain and inflammation in horses, particularly in cases of lameness or post-surgical recovery. Its potent anti-inflammatory and analgesic properties make it a valuable tool in improving animal welfare and ensuring faster recovery from illness or injury.
