What Is Naproxen?

Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) commonly used to relieve pain, inflammation, and swelling associated with various conditions. As an NSAID, it works by inhibiting the production of prostaglandins, chemicals in the body that contribute to pain and inflammation. Naproxen is available both over-the-counter and in prescription-strength formulations.

Its primary uses include the management of conditions such as osteoarthritis, rheumatoid arthritis, gout, and ankylosing spondylitis. Additionally, naproxen is often employed to alleviate pain from injuries, menstrual cramps, and headaches. It belongs to the same class of medications as ibuprofen and aspirin.

Naproxen is available in various forms, including tablets, extended-release tablets, and liquid formulations. It is typically taken with food or milk to reduce the risk of stomach upset. While generally considered effective, naproxen, like other NSAIDs, is associated with potential side effects, including gastrointestinal issues and an increased risk of cardiovascular events. Individuals with certain medical conditions or taking specific medications should consult their healthcare provider before using naproxen to ensure its suitability for their circumstances.
