Naprosyn (Naproxen Sodium) - Summary

 
 



Cardiovascular Risk

  • NSAIDs may cause an increased risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. This risk may increase with duration of use. Patients with cardiovascular disease or risk factors for cardiovascular disease may be at greater risk (see WARNINGS).
  • Naproxen as NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension is contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery (see WARNINGS).

Gastrointestinal Risk

  • NSAIDs cause an increased risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients are at greater risk for serious gastrointestinal events (see WARNINGS).
 

NAPROSYN SUMMARY

Cardiovascular Risk

Naproxen is a member of the arylacetic acid group of nonsteroidal anti-inflammatory drugs.

Naproxen as NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension are indicated for the treatment of rheumatoid arthritis, osteoarthritis, ankylosing spondylitis and juvenile arthritis.

Naproxen as NAPROSYN Suspension is recommended for juvenile rheumatoid arthritis in order to obtain the maximum dosage flexibility based on the patient's weight.

Naproxen as NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension are also indicated for the treatment of tendonitis, bursitis, acute gout, and for the management of pain and primary dysmenorrhea. EC-NAPROSYN is not recommended for initial treatment of acute pain because the absorption of naproxen is delayed compared to absorption from other naproxen-containing products (see CLINICAL PHARMACOLOGY and DOSAGE AND ADMINISTRATION).

Impact of a Fixed-Dose Combination of Naproxen and Esomeprazole Magnesium on Serum Thromboxane B(2) Inhibition by Low-Dose Aspirin Over 5 Days in Healthy Adults: A Phase I, Randomized, Double-Blind, Placebo-Controlled, Noninferiority Trial. [2011.11.09]
Background: Low-dose aspirin (LDA) and nonsteroidal anti-inflammatory drugs (NSAIDs) are often used concomitantly; however, some NSAIDs may interfere with LDA antiplatelet activity. OBJECTIVE: We evaluated the impact of coadministered enteric-coated naproxen 500 mg and immediate-release esomeprazole magnesium 20 mg (fixed-dose combination) on LDA-mediated platelet cyclooxygenase (COX)-1 inhibition... CONCLUSIONS: This pilot investigation suggests that LDA coadministered with naproxen/esomeprazole magnesium is noninferior to LDA alone for platelet COX-1 inhibition, as measured by serum TXB(2) concentration, in healthy volunteers.

Naprosyn review by 50 year old female patient

  Rating
Overall rating:  
Effectiveness:   Ineffective
Side effects:   Mild Side Effects
  
Treatment Info
Condition / reason:   muscle inflammation
Dosage & duration:   500 mg taken 2 times a day for the period of 6 weeks
Other conditions:   whiplash
Other drugs taken:   none
  
Reported Results
Benefits:   None. I was told it would take 6 weeks for the medicine to accumulate and become completely effective. It did not produce any results that were apparent. Not in inflammation reduction or in pain reduction due to the inflammation were any results ascertainable. I suffered while waiting for this medication to do anything. Further, you are told to consume food to protect the lining of your stomach from this medication. Not always something you want to do when you are experiencing a lot of pain because pain can make you feel like vomiting.
Side effects:   Stomach issues, burning The more adverse affect was the constant pain due to the continuing inflammation with the added and increasing reduction in movement, and muscle usage. Worst, was the waste of time. Another med could have been prescribed in the time I used this medicine that would have been more effective and time healing would not have been wasted. In fact, another anti-inflammatory was prescribed that provided immediate benefits (30 minutes) without the build-up in your system that the M.D. and pharmacist said Naprosyn requires before it becomes effective.
Comments:   Tried various dosages from the lowest, to more frequency. It simply had little affect on inflammation or pain. No other pain medication was added to this treatment and no other medication was given. I had a car accident and suffered whiplash, thoracic muscle strain, herniation of entire lumbar region, etc. Inflammation was rampant from hip level up. Any relief would have been noted and appreciated. Another drug was later prescribed, another anti-inflammatory, which proved just how much the naprosyn did not work. I had immediate pain relief in 30 minutes and notable inflammation reduction very quickly. In fact, after a 3 week loading of this drug, I was able to get out of bed, move around, and be functional! The Doctor insisted on trying this level, Naprosyn, first and then changed after 6 weeks, to supposedly stronger medication in some kind of protocol progression. I now tell my doctors which medication works and refuse anything else. They waste time on ineffective medications allowing suffering. I saw the doctors within the 6 week period declaring and their noting how ineffective this medication was.
