Perform periodically renal function, CBC and chemistry profile in patients receiving long-term therapy.
Lactation: Drug excreted in breast milk; effect on infant unknown; not recommended
Pregnancy-Lactation
Pregnancy
There are no adequate and well-controlled studies in pregnant women; data from observational studies regarding potential embryofetal risks of NSAID use in women in the first or second trimesters of pregnancy are inconclusive; NSAIDs inhibit prostaglandin synthesis, cause delayed parturition, and increase the incidence of stillbirth
Lactation
The naproxen anion has been found in the milk of lactating women at a concentration equivalent to approximately 1% of maximum naproxen concentration in plasma; developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for therapy and any potential adverse effects on breastfed infant from therapy or from underlying maternal condition
Interactions
May enhance methotrexate toxicity. Reduced BP response to ACE inhibitors or angiotensin II receptor antagonists. Increased risk of serious GI events (e.g. ulcer) w/ aspirin. Increased risk of GI bleeding w/ warfarin. May reduce the natriuretic effects of furosemide or thiazide diuretics. May increase serum lithium concentrations and reduce renal lithium clearance.
Delayed absorption w/ antacids, colestyramine or sucralfate. May interfere w/ the antihypertensive effects of beta-blockers (e.g. propranolol). May increase serum levels w/ probenecid.

Mechanism of Action
Naproxen, a propionic acid derivative, is a prototypical NSAID. It reversibly inhibits the cyclooxygenase-1 and -2 (COX-1 and -2) enzymes, thus resulting in reduced synthesis of prostaglandin precursors. It can inhibit platelet aggregation, has anti-inflammatory, analgesic and antipyretic actions.
