YELLOX is a prescription eye drop medication primarily used to reduce inflammation and pain following cataract surgery. The active ingredient in YELLOX is bromfenac, which belongs to a class of drugs known as nonsteroidal anti-inflammatory drugs (NSAIDs). By inhibiting the action of certain enzymes (cyclooxygenase-1 and -2) involved in the production of prostaglandins, substances in the body that mediate inflammation and pain, YELLOX effectively reduces these symptoms. It is typically administered as a 0.9 mg/mL ophthalmic solution and is used according to a healthcare provider's directions, often starting the day after cataract surgery and continuing for a prescribed period to ensure proper healing and comfort.
