Etriflex 90 Tablet contains Etoricoxib 90mg, a selective cyclooxygenase-2 (COX-2) inhibitor used primarily for the management of pain and inflammation associated with various musculoskeletal conditions. It is commonly prescribed for osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and acute gouty arthritis, providing effective relief from joint pain, swelling, and stiffness. By selectively inhibiting the COX-2 enzyme, Etriflex 90 reduces the production of prostaglandins responsible for inflammation and pain, while minimizing gastrointestinal side effects often seen with non-selective NSAIDs. The tablet is typically taken once daily, with or without food, as directed by a healthcare professional. Patients should use Etriflex 90 with caution if they have a history of cardiovascular disease, gastrointestinal ulcers, or kidney impairment, and it is important to inform the doctor about any other medications being taken to avoid potential drug interactions. Common side effects may include headache, dizziness, and gastrointestinal discomfort. Etriflex 90 is not recommended during pregnancy or breastfeeding unless specifically advised by a physician. Always follow the prescribed dosage and consult a healthcare provider if symptoms persist or worsen.
