Celenax belongs to a group of medicines called nonsteroidal anti-inflammatory drugs (NSAID), and specifically a sub-group known as cyclooxygenase-2 (COX-2) inhibitors. Your body makes prostaglandins that may cause pain and inflammation. In conditions such as rheumatoid arthritis and osteoarthritis your body makes more of these. Celenax acts by reducing the production of prostaglandins, thereby reducing the pain and inflammation. Celenax is used in adults for the relief of signs and symptoms of rheumatoid arthritis, osteoarthritis and ankylosing spondylitis. You should expect your medicine to start working within hours of taking the first dose, but you may not experience a full effect for several days.
