Cataheal 100mg Tablet is used to relieve pain and inflammation associated with osteoarthritis, rheumatoid arthritis and ankylosing spondylitis. It works by blocking the action of chemical messengers that cause pain and inflammation. Besides this, it helps reduce swelling and inflammation by breaking down the abnormal proteins at the site of inflammation. In some cases, this medicine may cause side effects such as nausea, vomiting, stomach upset, diarrhoea, headache, and dizziness. Before taking this medicine, you should tell your doctor if you are allergic to any of its components or if you are pregnant/breastfeeding, and about all the medications you are taking and pre-existing medical conditions.
