Naprosyn is a pain medication used to reduce inflammation and pain caused by various conditions including arthritis, tendinitis, and menstrual cramps.

Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that blocks the binding of some enzymes to produce analgesic and anti-inflammatory effects by reducing prostaglandin synthesis. This inhibitory action allows Naprosyn to reduce pain related to inflammation for a variety of conditions, especially rheumatic ones.

This anti-inflammatory medication is a good alternative to aspirin and other NSAIDs because Naprosyn has proven more tolerable with a lower incidence of adverse events. Naproxen also has a longer half-life meaning that fewer doses are needed each day.

Uses and Dosage

The dose of Naprosyn that is prescribed will vary depending on the individual and condition being treated. Always follow your doctor’s directives and read packaging labels carefully.

  • Swallow tablet whole
  • For arthritis and ankylosing spondylitis, most take 250 or 500mg twice daily
  • Doses can increase up to 1500mg a day for periods of up to 6 months when required
  • For pain management and acute tendonitis or bursitis, most take 500mg and then 250mg every 6 to 8 hours as needed
  • For acute goat, adults are recommended to start with 750mg and then take 250mg every 8 hours until the attack has subsided
  • Doses generally shouldn’t exceed 1200mg a day
  • Store at room temperature away from moisture and heat

Side Effects

Naprosyn may cause some side effects to develop while it reduces pain and inflammation. Speak with your doctor for more information regarding any symptoms you may encounter when taking naproxen.

  • Headache, dizziness, drowsiness

  • Swelling or rapid weight gain
  • Any skin rash no matter how mild
  • Signs of stomach bleeding (bloody or tarry stools, coughing up blood, vomit that looks like coffee grounds)

Allergic Reactions

Do not take Naprosyn if you are allergic to naproxen or if you have ever had an allergic reaction after using Naprosyn. If you develop signs of an allergic reaction, stop using this medication and contact your doctor.

Naprosyn allergy symptoms may include:

  • Runny or stuffy nose
  • Wheezing or trouble breathing
  • Hives
  • Swelling in face or throat
  • Fever
  • Sore throat
  • Burning eyes
  • skin pain

Do not use Naprosyn if you have a history of allergic reaction to aspirin or other NSAIDs.

Naproxen may increase your risk of having a fatal heart attack or stroke, especially if taken long-term, at high doses, or if you have heart disease.

Do not use Naprosyn immediately before or after having heart bypass surgery to help avoid complications.

Seek immediate medical attention if you have chest pain, weakness, shortness of breath, slurred speech, or problems with vision or balance.

Naproxen may cause stomach or intestinal bleeding which could be fatal. This is more likely to occur in older adults taking Naprosyn but can happen to anyone without warning during treatment.

Avoid drinking alcohol while taking Naprosyn because it can increase your risk of stomach bleeding.

Avoid taking aspirin or other NSAIDs at the same time as Naprosyn unless told to do so by your doctor.

Consult with your doctor to determine the safety of you taking Naprosyn if you have any of the following:

  • Heart disease, high blood pressure, high cholesterol, diabetes, or if you smoke
  • History of heart attack, stroke, or blood clot
  • History of stomach ulcers or bleeding
  • Asthma
  • Liver or kidney disease
  • Fluid retention
  • if you take aspirin daily to prevent a heart attack or stroke

Consult with your doctor about taking medication for pain, arthritis, fever, or swelling with Naprosyn. Many over the counter medicines contain similar ingredients to naproxen, such as aspirin or salicylates, and can cause you to have too much of a certain type in your system.

Ask your doctor before taking an antacid and only use what your doctor recommends. Some antacids can decrease your body’s ability to absorb naproxen.

Some other drugs can interact with naproxen and cause adverse reactions. Tell your doctor about all the medications you take, including over the counter medicine, vitamins, and herbal products, but especially any of the following:

  • Cholestyramine
  • Cyclosporine
  • Digoxin
  • Lithium
  • Methotrexate
  • Pemetrexed
  • Phenytoin or similar seizure medications
  • Probenecid
  • Warfarin or similar blood thinners
  • Diuretic
  • Heart or blood pressure medication
  • Insulin or oral diabetes medicine

Consult with your doctor before taking Naproxen if you also take an antidepressant such as citalopram, escitalopram, fluoxetine, paroxetine, or vilazodone. When used in combination with any NSAID these medications can cause you to bruise or bleed easily.

Do not use Naprosyn while pregnant unless your doctor explicitly tells you to do so. Taking any NSAID during the last 20 weeks of pregnancy can lead to complications as well as serious heart or kidney problems in your baby.

Ask your doctor about the risks of breastfeeding while using Naprosyn.

Consult with your doctor before giving this medication to anyone under 12 years of age.

Naprosyn is not an approved treatment for anyone younger than the age of 2. Do not give this pain medication to any child without first consulting your doctor.

What is the difference between Naproxen and Ibuprofen?

Both naproxen and ibuprofen are nonsteroidal anti-inflammatory drugs (NSAIDs) used to reduce pain and inflammation, but they differ in some ways. Naproxen is a long-acting drug that allows for less frequent dosing than ibuprofen, but it is more likely to cause an upset stomach.

How long does Naprosyn stay in your system?

Naproxen is a long-acting NSAID with an elimination half-life of 12 to 17 hours. This means that the drug takes this long to reduce its concentration by half until it is eliminated from your system. Naprosyn should therefore be out of your system within 94 hours, depending on your dosage and your body’s metabolism.
