side effects, nutrient depletions, herbal interactions and health notes:
• Avoid alcohol. Alcohol use with this medication heightens the risk of gastric ulceration and bleeding.1
• Naproxen may also hinder absorption of folic acid and vitamin C.2
• Naproxen may raise blood potassium levels, especially in the elderly or in those with poor kidney function.3
• Take Naproxen with food to avoid stomach irritation.4
• Licorice may protect the stomach against NSAID damage.5
• The Food and Drug Administration (FDA) is working with the National Institutes of Health to review the available scientific information on naproxen following the decision of the National Institute on Aging to halt a clinical trial studying non-steroidal anti-inflammatory drugs in patients at risk of developing Alzheimer's disease. Preliminary information from the study showed some evidence of increased risk of cardiovascular events, when compared to placebo, to patients taking naproxen. In the meantime, FDA advises patients who are currently taking over-the-counter naproxen products to carefully follow the instructions on the label. Patients should not exceed the recommended doses for naproxen (220 milligrams twice daily) and should not take naproxen for longer than ten days unless a physician directs otherwise. Patients with questions about naproxen should consult their physicians.6
