Dysmenorrhea: 500 mg should be given initially followed by 250 mg at 6-8 hour intervals for up to 5 days.

CNS: Headache, insomnia, inability to concentrate and cognitive dysfunction have been reported.

Naproxen should be given under close supervision to patients with a history of gastrointestinal disease. As Naproxen is eliminated to a large extent (95%) by urinary excretion via glomerular filtration, it should be used with great caution in patients with impaired renal function and the monitoring of serum creatinine clearance is advised in these patients. Naproxen is not recommended in patients having baseline creatinine clearance less than 20 ml/minute.

Naproxen should be used during pregnancy only if the potential benefits justify the potential risks to the fetus. Naproxen has been found in the milk of lactating mothers. Because of the possible adverse effects of prostaglandin-inhibiting drug on neonates, use in nursing mother should be avoided.

Naproxen can reduce the anti-hypertensive effect of propranolol and other beta-blockers. Probenecid given concurrently increases Naproxen plasma levels and extends its half-life considerably. Concurrent administration of methotrexate may enhance its toxicity due to reduced tubular secretion.

Significant over dosage of the drug may be characterized by drowsiness, heartburn, indigestion, and nausea or vomiting. Animal studies indicate that the prompt administration of activated charcoal in adequate amounts would tend to reduce markedly the absorption of the drug.

Keep in a cool and dry place (30°C), protected from light. Keep out of the reach of children.

Active peptic ulceration and hypersensitivity to Naproxen. Naproxen should not be given to patients in whom aspirin or other nonsteroidal anti-inflammatory/analgesic drugs induce asthma, rhinitis or urticaria.
