Naprosyn

Naprosyn® (naproxen) is a prescription medicine used to reduce pain, inflammation, fever, and stiffness caused by many conditions, including injury, arthritis, gout, menstrual cramps, and other types of bone, muscle, or tendon pain. Naprosyn is part of a class of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). It comes in two forms -- Naprosyn (immediate-release) and EC-Naprosyn® (delayed-release).


Naprosyn is in a group of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). Naproxen works by reducing hormones that cause inflammation and pain in the body.


Naprosyn is used to treat pain or inflammation caused by conditions such as arthritis, ankylosing spondylitis, tendinitis, bursitis, gout, or menstrual cramps.


Naprosyn may also be used for other purposes not listed in this medication guide.



Side Effects

Get emergency medical help if you have any of these signs of an allergic reaction to Naprosyn: hives; difficulty breathing; swelling of your face, lips, tongue, or throat. Stop taking Naprosyn and seek medical attention or call your doctor at once if you have any of these serious side effects:



Less serious Naprosyn side effects may include:



This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.


Important information about Naprosyn

Naprosyn can increase your risk of life-threatening heart or circulation problems, including heart attack or stroke. This risk will increase the longer you use Naprosyn. Do not use Naprosyn just before or after having heart bypass surgery (also called coronary artery bypass graft, or CABG).


Seek emergency medical help if you have symptoms of heart or circulation problems, such as chest pain, weakness, shortness of breath, slurred speech, or problems with vision or balance.


Naprosyn can also increase your risk of serious effects on the stomach or intestines, including bleeding or perforation (forming of a hole). These conditions can be fatal and gastrointestinal effects can occur without warning at any time while you are taking Naprosyn. Older adults may have an even greater risk of these serious gastrointestinal side effects.


Call your doctor at once if you have symptoms of bleeding in your stomach or intestines. This includes black, bloody, or tarry stools, or coughing up blood or vomit that looks like coffee grounds.


Do not use any other over-the-counter cold, allergy, or pain medication without first asking your doctor or pharmacist. Many medicines available over the counter contain aspirin or other medicines similar to Naprosyn (such as ibuprofen or ketoprofen). If you take certain products together you may accidentally take too much of this type of medication. Read the label of any other medicine you are using to see if it contains aspirin, ibuprofen, or ketoprofen.


Do not drink alcohol while taking Naprosyn. Alcohol can increase the risk of stomach bleeding caused by Naprosyn. Avoid prolonged exposure to sunlight. Naprosyn can make your skin more sensitive to sunlight, and a sunburn may result.


Precautions and Warnings With Naprosyn

Asthma and diabetes are among the conditions you should let your healthcare provider know about before you take Naprosyn. A few of the people who should not take this medicine include those with an active bleeding condition, those who are allergic to Naprosyn or its inactive components.


Those who are pregnant or want to become pregnant must not take this medicine too.


Those who are breast-feeding: Naproxen appears in breast milk and could affect a nursing infant. If naproxen is essential to your health, you must discontinue breastfeeding until your treatment with naproxen is finished.


Some other precautions and warnings with Naprosyn include potential drug interactions, the risk of a heart attack or stroke in some people taking the drug, and the safety of taking Naprosyn if you have high blood pressure.


You should talk with your healthcare provider prior to taking Naprosyn® (naproxen) if you have:


Also let your healthcare provider know if you:


Also tell your healthcare provider about all other medicines you may be currently taking, including prescription and non-prescription medicines, vitamins, and herbal supplements.



Uses and Benefits of Naprosyn

Arthritis symptoms, painful menstrual cramps, and general pain, among other things, can all be treated with Naprosyn. The medicine can also be prescribed to children over the age of 2 for juvenile arthritis, and to children ages 12 and over for the reduction of pain and fever. Off-label uses for Naprosyn include treating symptoms of fibromyalgia or chronic fatigue syndrome.


Naprosyn uses include:


Naprosyn may be combined with other medications in several common cold, allergy, and flu products to help relieve common cold symptoms, such as fever or aches and pains.


How Does Naprosyn Work?

Naprosyn and other nonsteroidal anti-inflammatory drugs (NSAIDs) work by inhibiting the action of certain hormones (called prostaglandins) that cause inflammation and pain in the body. By blocking the effects of prostaglandins, Naprosyn is useful at reducing fever and pain related to a number of conditions. This includes pain and joint swelling associated with different forms of arthritis and other conditions, and pain related to inflammation or bone, muscle, or tendon injury.


Can Children Use Naprosyn?

Children over the age of two can use Naprosyn for the treatment of juvenile arthritis symptoms.

Off-Label Uses

On occasion, your healthcare provider may recommend this product for treating something other than the conditions discussed in this article. This is called an “off-label” use. At this time, there are several off-label Naprosyn uses. These include the treatment of:



Dosage

This dosage information does not include all the information needed to use Naprosyn safely and effectively. See full prescribing information for Naprosyn. The information here is not a substitute for medical advice. ALWAYS consult your doctor or pharmacist.


Geriatric Patients

Studies indicate that although total plasma concentration of naproxen is unchanged, the unbound plasma fraction of naproxen is increased in the elderly. Caution is advised when high doses are required and some adjustment of dosage may be required in elderly patients. As with other drugs used in the elderly, it is prudent to use the lowest effective dose.


Patients With Moderate to Severe Renal Impairment

Naproxen-containing products (such as Naprosyn) are not recommended for use in patients with moderate to severe and severe renal impairment (creatinine clearance <30 ml/min).

To maintain the integrity of the enteric coating, the EC-NAPROSYN tablet should not be broken, crushed or chewed during ingestion. NAPROSYN Suspension should be shaken gently before use.


During long-term administration, the dose of naproxen may be adjusted up or down depending on the clinical response of the patient. A lower daily dose may suffice for long-term administration. The morning and evening doses do not have to be equal in size and the administration of the drug more frequently than twice daily is not necessary.


In patients who tolerate lower doses well, the dose may be increased to naproxen 1500 mg/day for limited periods of up to 6 months when a higher level of anti-inflammatory/analgesic activity is required. When treating such patients with naproxen 1500 mg/day, the physician should observe sufficient increased clinical benefits to offset the potential increased risk. The morning and evening doses do not have to be equal in size and administration of the drug more frequently than twice daily does not generally make a difference in response.


Juvenile Arthritis

The use of NAPROSYN Suspension is recommended for juvenile arthritis in children 2 years or older because it allows for more flexible dose titration based on the child's weight. In pediatric patients, doses of 5 mg/kg/day produced plasma levels of naproxen similar to those seen in adults taking 500 mg of naproxen.


The recommended total daily dose of naproxen is approximately 10 mg/kg given in 2 divided doses (ie, 5 mg/kg given twice a day). A measuring cup marked in 1/2 teaspoon and 2.5 milliliter increments is provided with the NAPROSYN Suspension. The following table may be used as a guide for dosing of NAPROSYN Suspension:

Acute Pain Including Painful Menstrual Periods

For acute pain relief or treatment of painful menstrual periods, the usual adult dose is Naprosyn 500 mg to start, followed by 250 mg every six to eight hours as needed. The maximum recommended daily dosage of Naprosyn is 1250 mg per day.

Rheumatoid Arthritis, Osteoarthritis, and Ankylosing Spondylitis

The recommended starting dosage of Naprosyn for most people with rheumatoid arthritis, osteoarthritis, or ankylosing spondylitis is Naprosyn 250 mg, 375 mg, or 500 mg twice a day. After several weeks, if pain is still present, your healthcare provider may choose to increase your dose up to a maximum of Naprosyn 1500 mg per day. If pain still does not improve, your healthcare provider may recommend other options for pain relief.

If you are prescribed EC-Naproxyn®, the recommended dosage is 375 mg or 500 mg twice a day.


Acute Gout

The recommended starting dose is 750 mg of NAPROSYN followed by 250 mg every 8 hours until the attack has subsided. EC-NAPROSYN is not recommended because of the delay in absorption.

Naprosyn (naproxen) for Rheumatoid Arthritis: I've had RA for 4 years. 500mg naproxen tablets were my first treatment. They definitely helped the day get better and be able to function daily. However, they did not stop the morning stiffness and pain or the build up of inflamation in my body. I definitely needed a more serious drug to stop the progression of the disease.

Comment: It was as if it was immediate relief because within 6 - 8 hrs. I no longer had the excruciating pain in my heal that nearly crippled me. I could hardly walk and now I can walk without limping. It was throwing my alignment of my spine out. I am very thankful for this drug. I am thankful my doctor prescribed this medication. My doctor said it was an inflamation in my heal.
