It belongs to the Non-Steroidal Anti-inflammatory Drugs (NSAIDs) class and is indicated in the treatment of musculo-skeletal disorders such as arthritis, acute attack of gout etc. It is not used in migraine. Long-term use of Xenobid can result in a number of serious side effects such as high blood pressure, peptic ulcers, oedema, blood disorders, serious cardiovascular and cerebrovascular events etc.
