OLIDA 100 mg is a non-steroidal anti-inflammatory drug (NSAID) that contains sulindac, used to relieve pain and inflammation associated with conditions like rheumatoid arthritis, ankylosing spondylitis, bursitis, gout, and acute shoulder pain. It works by inhibiting the cyclooxygenase (COX) enzymes responsible for the production of prostaglandins, which are chemicals that promote inflammation and pain. By reducing these chemicals, sulindac helps alleviate symptoms like swelling, pain, and fever. OLIDA 100 mg is typically taken in doses of 100 mg to 200 mg twice daily, and it should be taken with food to reduce gastrointestinal side effects. Like other NSAIDs, it may cause side effects like gastrointestinal discomfort, nausea, or headaches, and it should be used cautiously in individuals with a history of stomach ulcers or gastrointestinal bleeding. It is important to use this medication under medical supervision to ensure safety and effectiveness.
