Naprosyn SR is a medication that belongs to a family of medicines called Non-Steroidal Anti-Inflammatory Drugs (NSAIDs). It is primarily used to relieve pain and reduce inflammation.

Use and Dosage

The recommended starting dose of naproxen controlled-release is 750 mg taken once daily.

Your doctor may adjust your dose according to your response. The lowest dose needed to control pain and inflammation should be used.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

Naproxen controlled-release is best taken after a meal, or with food or milk. Do not lie down for about 15 minutes to 30 minutes after taking this medication. Swallow the tablets whole, and do not crush or chew them.

It is important to take this medication exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed dose. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store this medication at room temperature and keep it out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

Get emergency medical help if you have signs of an allergic reaction to naproxen (runny or stuffy nose, wheezing or trouble breathing, hives, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling).

Stop using naproxen and seek medical treatment if you have a serious drug reaction that can affect many parts of your body. Symptoms may include skin rash, fever, swollen glands, muscle aches, severe weakness, unusual bruising, or yellowing of your skin or eyes.

  • Kidney problems – little or no urinating, painful or difficult urination, swelling in your feet or ankles, feeling tired or short of breath

Naprosyn SR is available in the following forms and strengths:

  • Naprosyn SR SA tablet:
    • 750 mg


What happens if I miss a dose?

Since naproxen 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 for the missed dose.

What happens if I overdose?

Seek emergency medical attention.

What to avoid?

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

Avoid taking aspirin or other NSAIDs unless your doctor tells you to.

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 (such as ibuprofen or ketoprofen). Taking certain products together can cause you to get too much of this type of medication.

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