- Differential Diagnosis
- Try building your search one term at a time, and be as specific as you can! Search term example: "chronic cough".
- Do not enter multiple findings such as "anemia, chronic cough, weight loss, vomiting" all at the same time.
- After selecting your term from the search results a list of possible diagnoses will be generated. If the list is too long, you will be able to narrow it down by entering additional terms.
- Do not enter values such as "heart rhythm 110" or "sodium 125", instead use "tachycardia" or "hyponatremia".

Carefully consider the potential benefits and risks of naproxen, naproxen sodium and other treatment options before deciding to use naproxen and naproxen sodium tablets. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals (see WARNINGS).
After observing the response to initial therapy with naproxen or naproxen sodium the dose and frequency should be adjusted to suit an individual patient's needs.
Different dose strengths and formulations (ie, tablets, suspension) of the drug are not necessarily bioequivalent. This difference should be taken into consideration when changing formulation.
Although naproxen and naproxen sodium circulate in the plasma as naproxen, they have pharmacokinetic differences that may affect onset of action. Onset of pain relief can begin within 30 minutes in patients taking naproxen sodium and within 1 hour in patients taking naproxen.
The recommended strategy for initiating therapy is to choose a formulation and a starting dose likely to be effective for the patient and then adjust the dosage based on observation of benefit and/or adverse events. A lower dose should be considered in patients with renal or hepatic impairment or in elderly patients (see WARNINGS and PRECAUTIONS).
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) (see WARNINGS: Renal Effects).

During long-term administration, the dose of naproxen may be adjusted up or down depending on the clinical response of the patient. A lower daily dose may suffice for long-term administration. The morning and evening doses do not have to be equal in size and the administration of the drug more frequently than twice daily is not necessary.
In patients who tolerate lower doses well, the dose may be increased to naproxen 1500 mg/day for limited periods of up to 6 months when a higher level of anti-inflammatory/ analgesic activity is required. When treating such patients with naproxen 1500 mg/day, the physician should observe sufficient increased clinical benefits to offset the potential increased risk. The morning and evening doses do not have to be equal in size and administration of the drug more frequently than twice daily does not generally make a difference in response (see CLINICAL PHARMACOLOGY).
The recommended total daily dose of naproxen is approximately 10 mg/kg given in 2 divided doses (ie, 5 mg/kg given twice a day).
Management of Pain, Primary Dysmenorrhea, and Acute Tendonitis and Bursitis
The recommended starting dose is 550 mg of naproxen sodium as naproxen sodium tablet followed by 550 mg every 12 hours or 275 mg every 6 to 8 hours as required. The initial total daily dose should not exceed 1375 mg of naproxen sodium. Thereafter, the total daily dose should not exceed 1100 mg of naproxen sodium. Because the sodium salt of naproxen is more rapidly absorbed, naproxen sodium tablets are recommended for the management of acute painful conditions when prompt onset of pain relief is desired. Naproxen may also be used for initial treatment of acute pain (see CLINICAL PHARMACOLOGY, INDICATIONS AND USAGE).
The recommended starting dose is 750 mg of naproxen followed by 250 mg every 8 hours until the attack has subsided. Naproxen sodium may also be used at a starting dose of 825 mg followed by 275 mg every 8 hours.
