What are the uses of this medicine?[edit | edit source]

Naproxen as naproxen or naproxen sodium tablets are indicated:

  • Naproxen as naproxen suspension is recommended for juvenile rheumatoid arthritis in order to obtain the maximum dosage flexibility based on the patient’s weight.

Naproxen as naproxen and naproxen sodium tablets are also indicated:

  • For relief of the signs and symptoms of tendonitis
  • For relief of the signs and symptoms of bursitis
  • For relief of the signs and symptoms of acute gout
  • For the management of pain
  • For the management of primary dysmenorrhea


How does this medicine work?[edit | edit source]

  • Naproxen (na prox' en) belongs to the propionic acid class of NSAIDs similar to fenoprofen, ibuprofen, ketoprofen and oxaprozin. The anti inflammatory and analgesic properties of NSAIDs such as naproxen are mediated by inhibition of tissue cyclo-oxygenases (Cox-1 and -2), which results in a decrease in pro-inflammatory prostaglandins, important mediators in inflammatory and pain pathways.
  • Naproxen has analgesic as well as antipyretic and antiinflammatory activity.
  • It has a longer half-life than other commonly used NSAIDs, making a twice daily regimen feasible.

What special precautions should I follow?[edit | edit source]

  • Several COX-2 selective and nonselective NSAIDs of up to three years duration have shown an increased risk of serious cardiovascular (CV) thrombotic events, myocardial infarction, and stroke, which can be fatal.
  • NSAIDs, including naproxen and naproxen sodium, can lead to onset of new hypertension or worsening of pre-existing hypertension, either of which may contribute to the increased incidence of CV events. Blood pressure (BP) should be monitored closely during the initiation of NSAID treatment and throughout the course of therapy.
  • Fluid retention, edema, and peripheral edema have been observed in some patients taking NSAIDs. Naproxen and naproxen sodium should be used with caution in patients with fluid retention, hypertension, or heart failure.
  • NSAIDs, including naproxen and naproxen sodium, can cause serious gastrointestinal (GI) adverse events including inflammation, bleeding, ulceration, and perforation of the stomach, small intestine, or large intestine, which can be fatal. NSAIDs should be given with care to patients with a history of inflammatory bowel disease (ulcerative colitis, Crohn’s disease) as their condition may be exacerbated.
  • Long-term administration of NSAIDs has resulted in renal papillary necrosis and other renal injury. Patients at greatest risk of this reaction are those with impaired renal function, hypovolemia, heart failure, liver dysfunction, salt depletion, those taking diuretics and ACE inhibitors, and the elderly.
  • No information is available from controlled clinical studies regarding the use of naproxen or naproxen sodium in patients with advanced renal disease. Therefore, treatment with naproxen and naproxen sodium is not recommended in these patients with advanced renal disease.
  • As with other NSAIDs, anaphylactoid reactions may occur in patients without known prior exposure to naproxen or naproxen sodium. Emergency help should be sought in cases where an anaphylactoid reaction occurs. Anaphylactoid reactions, like anaphylaxis, may have a fatal outcome.
  • NSAIDs, including naproxen and naproxen sodium, can cause serious skin adverse events such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which can be fatal. Patients should be informed about the signs and symptoms of serious skin manifestations and use of the drug should be discontinued at the first appearance of skin rash or any other sign of hypersensitivity.
  • In late pregnancy, as with other NSAIDs, naproxen and naproxen sodium should be avoided because it may cause premature closure of the ductus arteriosus.


What to do in case of emergency/overdose?[edit | edit source]

Symptoms of overdosage may include:

Management of overdosage:

  • Patients should be managed by symptomatic and supportive care following a NSAID overdose.
  • There are no specific antidotes.
  • Hemodialysis does not decrease the plasma concentration of naproxen because of the high degree of its protein binding.
  • Emesis and/or activated charcoal (60 to 100 g in adults, 1 to 2 g/kg in children) and/or osmotic cathartic may be indicated in patients seen within 4 hours of ingestion with symptoms or following a large overdose.
  • Forced diuresis, alkalinization of urine or hemoperfusion may not be useful due to high protein binding.


Can this medicine be used in pregnancy?[edit | edit source]

  • Pregnancy Category C.
  • There are no adequate and well-controlled studies in pregnant women.
  • Naproxen and naproxen sodium should be used in pregnancy only if the potential benefit justifies the potential risk to the fetus.
