Naproxen is used for pain, swelling, and stiffness connected with arthritis or painful menstrual periods. May cause stomach problems. It may be taken with food or milk to prevent nausea.
Naproxen is both an over-the-counter and a prescription medication. The over-the-counter form is used to treat minor aches and pains, and to reduce fever. The prescription form is used to reduce pain, redness, swelling, and heat (inflammation) from conditions such as different types of arthritis, menstrual cramps, and other types of short-term pain. Naproxen belongs to a class of drugs called non-steroidal anti-inflammatory drugs, or NSAIDs. These work by stopping substances in your body that cause inflammation and pain.
Naproxen comes as a regular tablet, an enteric coated tablet (delayed-release tablet), an extended-release (long-acting) tablet, and a suspension (liquid) to take by mouth. The extended-release tablets are usually taken once a day. The tablets, enteric coated tablets, and suspension are usually taken twice a day for arthritis. The tablets and suspension are usually taken every 8 hours for gout, and every 6 to 8 hours as needed for pain. If you are taking naproxen on a regular basis, you should take it at the same time(s) every day.
Naproxen is available as tablets, caplets, gelcaps, and liquid gels to take by mouth. It is usually taken every 8 to 12 hours.
Common side effects of naproxen include stomach pain, heartburn, nausea, and gas. Naproxen can aslo cause dizziness or drowsiness. Do not drive or operate heavy machinery until you know how this medication will affect you.
