Naprosyn (Naproxen) belongs to a class of medications called nonsteroidal anti-inflammatory drugs (NSAIDs). This medication works by stopping the body's production of a substance that causes pain, fever, and inflammation. Naprosyn is used for treating pain or inflammation caused by conditions such as rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, tendinitis, bursitis, gout, or menstrual cramps. This medicine could be used to treat dental pain, headache, or painful monthly periods.

What happens if I miss a dose?

Since Naprosyn is sometimes used only when needed, you may not be on a dosing schedule.

If you are on a schedule, use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line. 

Where should I keep my medicine?

Keep out of reach of children.

Store at room temperature. Keep container tightly closed.

Throw away any unused medicine after the expiration date.

What should I avoid while taking Naprosyn?

Avoid drinking alcohol. It may increase your risk of stomach bleeding.

Avoid taking aspirin while you are taking Naprosyn.

You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medicine affects you.

Ask your doctor before taking any other medication for pain, arthritis, fever, or swelling. Many medicines available over the counter contain aspirin, salicylates, or other medicines similar to naproxen.

Ask your doctor using an antacid, and use only the type your doctor recommends. Some antacids can make it harder for your body to absorb naproxen.
