What to know about naproxen

What is naproxen?

Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) used for the treatment of pain, inflammation, and fever. It works by blocking the production of prostaglandins, which are substances in the body that cause pain and inflammation.


Naproxen is used for the treatment of mild to moderate pain, inflammation, and fever, including menstrual cramps, headaches, toothaches, and minor aches and pains.

The prescription form of naproxen is also used for the treatment of more severe pain, such as that associated with arthritis or an injury.

Brand names:

Some common brand names for naproxen include Aleve, Anaprox, EC-Naprosyn, and Naprosyn.


The active ingredient in naproxen is naproxen sodium. Other inactive ingredients in the medication may vary depending on the manufacturer and form of the medication.

Dosage and forms:

Naproxen is available in both over-the-counter and prescription forms. It can be taken orally in the form of tablets or capsules, and it is also available as a suspension for people who have difficulty swallowing pills.

The recommended dose of naproxen sodium depends on the reason for use and should be taken as directed by a healthcare provider.

Side effects:

Common side effects of naproxen sodium include upset stomach, heartburn, nausea, dizziness, and headache. More serious side effects can occur, such as stomach ulcers, bleeding, and kidney damage.


Naproxen sodium can interact with other medications, including blood-thinning medications, aspirin, and other NSAIDs. Taking naproxen sodium with these medications can increase the risk of stomach bleeding and other side effects.

People who are taking other medications should inform their healthcare provider before taking naproxen sodium to ensure that it is safe to take and to avoid any potential drug interactions.

Pregnancy and breastfeeding:

Naproxen should not be taken by women who are pregnant or breastfeeding.


People with a history of stomach problems, kidney disease, or liver disease should use naproxen sodium with caution.

People who are taking blood-thinning medications or have a history of bleeding disorders should also use naproxen sodium with caution.


Naproxen is a widely used NSAID that can be effective in relieving pain and reducing inflammation. As with all medications, it is important to use naproxen sodium exactly as directed by a healthcare provider and to be aware of potential side effects and interactions. If you have any questions or concerns about using naproxen sodium, it is best to consult with a healthcare provider.
