Celecoxib is a medication that belongs to a class of drugs known as nonsteroidal anti-inflammatory drugs (NSAIDs). It is primarily used to relieve pain, reduce inflammation, and lower fever. Celecoxib works by inhibiting an enzyme called cyclooxygenase-2 (COX-2), which plays a key role in the inflammatory process. This medication is commonly prescribed for conditions such as arthritis, acute pain, and menstrual discomfort. While it can be effective in managing pain and inflammation, it is important to use celecoxib under the guidance of a healthcare professional due to potential side effects and interactions with other medications.
