Naprosyn is a brand-name medication whose active ingredient is naproxen. It belongs to the non-steroidal anti-inflammatory drug (NSAID) class and is used to relieve pain, reduce inflammation, and lower fever. Naprosyn is supplied as an oral pill in strengths of 250 mg and 500 mg. In Hong Kong, it is a prescription-only product regulated by the Hong Kong Department of Health’s Drug Office.
Naproxen inhibits the cyclooxygenase enzymes COX-1 and COX-2, which are responsible for converting arachidonic acid into prostaglandins. Prostaglandins promote pain, fever, and inflammation. By reducing prostaglandin synthesis, naproxen:
The drug is well absorbed after oral intake, reaching peak plasma concentrations in about 2 hours. Its effects can last 12 hours or longer, which is why dosing is often twice daily. Naproxen is metabolised primarily in the liver and excreted in the urine.

Overdose: Symptoms may include nausea, vomiting, stomach pain, drowsiness, or ringing in the ears. Seek emergency medical assistance; treatment is mainly supportive.

Dosing adjustments for renal or hepatic impairment, or for elderly patients, should be made by a qualified clinician.
