Etorixib 90 mg Tablet contains etoricoxib, which is a non-steroidal anti-inflammatory drug (NSAID) that primarily helps reduce pain and inflammation. It does not address the underlying causes of autoimmune diseases or allergies, but it may help relieve pain, swelling, or joint discomfort associated with conditions such as rheumatoid arthritis or osteoarthritis. It should be used only under a doctor’s guidance, as long-term use or use in certain conditions can have side effects. For treating autoimmune diseases or allergies themselves, disease-specific medications or therapies prescribed by a doctor are required.
