Dosing and Administration

Geriatric Patients
Studies indicate that although total plasma concentration of Naproxen is unchanged, the unbound plasma fraction of Naproxen is increased in the elderly. Caution is advised when high doses are required and some adjustment of dosage may be required in elderly patients. As with other drugs used in the elderly, it is prudent to use the lowest effective dose.

Patients with Moderate to Severe Renal Impairment
Naproxen-containing products are not recommended for use in patients with moderate to severe and severe renal impairment (creatinine clearance < 30 mL/min).

Rheumatoid Arthritis, Osteoarthritis and Ankylosing Spondylitis

275 mg (Naproxen 250 mg with 25 mg sodium) twice daily
