Topica Adult: Apply Naproxen gel 2-6 times a day as required.
Hypersensitivity. Aspirin or NSAID allergy. Perioperative pain in the setting of CABG surgery. Pregnancy (3rd trimester)
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.
Pre-existing CV risk factors or disease e.g. fluid retention, CHF, hypertension. History of GI disease (bleeding or ulcers). Other forms of asthma. Hepatic impairment; closely monitor patients with any abnormal LFT. Renal impairment. Elderly. Lactation.
Oedema, palpitation, dizziness, drowsiness, headache, light headedness, vertigo, pruritus, skin eruption, ecchymosis, purpura, rash, fluid retention, abdominal pain, constipation, nausea, heartburn, diarrhoea, dyspepsia, stomatitis, flatulence, gross bleeding/perforation, indigestion, ulcers, vomiting, abnormal renal function, haemolysis, anaemia, increased bleeding time, elevated LFTs, visual disturbances, tinnitus, hearing disturbances, dyspnoea, diaphoresis, thirst. Potentially Fatal: Anaphylactic/anaphylactoid reactions. Exfoliative dermatitis, Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN).
Pregnancy category: C; D in 3rd trimester or near delivery.
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 ?-blockers (e.g. propranolol). May increase serum levels w/ probenecid.
