Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) commonly used to relieve pain, reduce inflammation, and lower fever. It works by inhibiting enzymes in the body that contribute to inflammation and pain signaling. Naproxen is often prescribed for conditions such as arthritis, menstrual cramps, and other types of acute pain. This medication is available in both prescription and over-the-counter forms. It is important to follow dosage instructions carefully, as excessive use can lead to side effects like stomach upset or increased risk of heart problems. Always consult a healthcare professional before starting or stopping naproxen.
