Clinical Drug Information
Indications & Usage
1 INDICATIONS AND USAGE Naproxen Sodium Controlled-Release Tablets are indicated for the treatment of: rheumatoid arthritis (RA) osteoarthritis (OA) ankylosing spondylitis (AS) tendinitis, bursitis acute gout primary dysmenorrhea (PD) the relief of mild to moderate pain [ see Warnings and Precautions ( 5 ) ]. Naproxen Sodium Controlled-Release Tablets is a nonsteroidal anti-inflammatory drug indicated for the treatment of: rheumatoid arthritis (RA)( 1 ) osteoarthritis (OA)( 1 ) ankylosing spondylitis (AS)( 1 ) tendinitis, bursitis ( 1 ) acute gout ( 1 ) primary dysmenorrhea (PD)( 1 ) the relief of mild to moderate pain ( 1 )
Dosage & Administration
2 DOSAGE AND ADMINISTRATION Use the lowest effective dosage for shortest duration consistent with individual patient treatment goals ( 2 ) RA, OA, and AS: The dosage is two 375 mg or 500 mg tablets once daily, or one 750 mg tablet once daily. Management of Pain, PD, and Acute Tendinitis and Bursitis: The dosage is two 500 mg tablets once daily. For patients requiring greater analgesic benefit, two 750 mg tablets or three 500 mg tablets may be used for a limited period. Thereafter, the total daily dose should not exceed two 500 mg tablets For the treatment of Acute Gout: The dosage is two to three 500 mg tablets once daily on the first day, followed by two 500 mg tablets once daily, until the attack has subsided. 2.1 General Dosing Instructions Carefully consider the potential benefits and risks of Naproxen Sodium Controlled-Release Tablets and other treatment options before deciding to use Naproxen Sodium Controlled-Release Tablets. Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [ see Warnings and Precautions ( 5 ) ]. After observing the response to initial therapy with Naproxen Sodium Controlled-Release Tablets, the dose and frequency should be adjusted to suit an individual patient’s needs. 2.2 Rheumatoid Arthritis, Osteoarthritis, and Ankylosing Spondylitis The recommended starting dose of Naproxen Sodium Controlled-Release Tablets in adults is two Naproxen Sodium Controlled-Release 375 mg tablets (750 mg) once daily, one Naproxen Sodium Controlled-Release 750 mg (750 mg) once daily, or two Naproxen Sodium Controlled-Release 500 mg tablets (1,000 mg) once daily. Patients already taking naproxen 250 mg, 375 mg, or 500 mg twice daily (morning and evening) may have their total daily dose replaced with Naproxen Sodium Controlled-Release Tablets as a single daily dose. During long-term administration, the dose of Naproxen Sodium Controlled-Release Tablets may be adjusted up or down depending on the clinical response of the patient. In patients who tolerate lower doses of Naproxen Sodium Controlled-Release Tablets well, the dose may be increased to two Naproxen Sodium Controlled-Release 750 mg tablets (1,500 mg), or three Naproxen Sodium Controlled-Release 500 mg tablets (1,500 mg) once daily for limited periods when a higher level of anti-inflammatory/analgesic activity is required. When treating patients, especially at the higher dose levels, the physician should observe sufficient increased clinical benefit to offset the potential increased risk [ see Clinical Pharmacology ( 12.3 ) ]. The lowest effective dose should be sought and used in every patient. Symptomatic improvement in arthritis usually begins within one week; however, treatment for two weeks may be required to achieve a therapeutic benefit. 2.3 Management of Pain, Primary Dysmenorrhea, and Acute Tendinitis and Bursitis The recommended starting dose is two Naproxen Sodium Controlled-Release 500 mg tablets (1,000 mg) once daily. For patients requiring greater analgesic benefit, two Naproxen Sodium Controlled-Release 750 mg tablets (1,500 mg) or three Naproxen Sodium Controlled-Release 500 mg tablets (1,500 mg) may be used for a limited period. Thereafter, the total daily dose should not exceed two Naproxen Sodium Controlled-Release 500 mg tablets (1,000 mg). 2.4 Acute Gout The recommended dose on the first day is two to three Naproxen Sodium Controlled-Release 500 mg tablets (1,000 to 1,500 mg) once daily, followed by two Naproxen Sodium Controlled-Release 500 mg tablets (1,000 mg) once daily, until the attack has subsided. 2.5 Dosage Adjustments in Patients with Hepatic Impairment A lower dose should be considered in patients with renal or hepatic impairment or in elderly patients [ see Warnings and Precautions ( 5.3 ) ]. 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. 2.1 General Dosing Instructions Carefully consider the potential benefits and risks of Naproxen Sodium Controlled-Release Tablets and other treatment options before deciding to use Naproxen Sodium Controlled-Release Tablets.

As with all drugs in this class, the frequency and severity of adverse events depends on several factors: the dose of the drug and duration of treatment; the age, the sex, physical condition of the patient; any concurrent medical diagnoses or individual risk factors. The following adverse reactions are divided into three parts based on frequency and whether or not the possibility exists of a causal relationship between drug usage and these adverse events. In those reactions listed as “Probable Causal Relationship” there is at least one case for each adverse reaction where there is evidence to suggest that there is a causal relationship between drug usage and the reported event. The adverse reactions reported were based on the results from two double-blind controlled clinical trials of three months duration with an additional nine month open-label extension. A total of 542 patients received Naproxen Sodium Controlled-Release Tablets either in the double-blind period or in the nine month open-label extension. Of these 542 patients, 232 received Naproxen Sodium Controlled-Release Tablets, 167 were initially treated with Naprosyn ® and 143 were initially treated with placebo.

Information for Patients
17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling ( Medication Guide ) that accompanies each prescription dispensed. Inform patients, families, or their caregivers of the following information before initiating therapy with naproxen sodium and periodically during the course of ongoing therapy. Cardiovascular Thrombotic Events Advise patients to be alert for the symptoms of cardiovascular thrombotic events, including chest pain, shortness of breath, weakness, or slurring of speech, and to report any of these symptoms to their health care provider immediately [ see Warnings and Precautions ( 5.1 ) ]. Gastrointestinal Bleeding, Ulceration, and Perforation Naproxen sodium, like other NSAIDs, can cause GI discomfort and, rarely, serious GI side effects, such as ulcers and bleeding, which may result in hospitalization and even death. Advise patients to report symptoms of ulcerations and bleeding, including epigastric pain, dyspepsia, melena, and hematemesis to their health care provider. In the setting of concomitant use of low-dose aspirin for cardiac prophylaxis, inform patients of the increased risk for and the signs and symptoms of GI bleeding [ see Warnings and Precautions ( 5.2 ) ]. Hepatotoxicity Inform patients of the warning signs and symptoms of hepatotoxicity (e.g., nausea, fatigue, lethargy, pruritus, diarrhea, jaundice, right upper quadrant tenderness, and “flu-like” symptoms). If these occur, instruct patients to stop naproxen sodium and seek immediate medical therapy [ see Warnings and Precautions ( 5.3 ) ]. Heart Failure and Edema Advise patients to be alert for the symptoms of congestive heart failure including shortness of breath, unexplained weight gain, or edema and to contact their healthcare provider if such symptoms occur [ see Warnings and Precautions ( 5.5 ) ]. Anaphylactic Reactions Inform patients of the signs of an anaphylactic reaction (e.g., difficulty breathing, swelling of the face or throat). Instruct patients to seek immediate emergency help if these occur [ see Contraindications ( 4 ) and Warnings and Precautions ( 5.7 ) ]. Serious Skin Reacti ons, including DRESS Naproxen sodium, like other NSAIDs, can cause serious skin side effects such as exfoliative dermatitis, SJS, and TEN, which may result in hospitalization and even death. Advise patients to stop taking naproxen sodium immediately if they develop any type of rash or fever and to contact their healthcare provider as soon as possible [ see Warnings and Precautions ( 5.9, 5.10) ]. Female Fertility Advise females of reproductive potential who desire pregnancy that NSAIDs, including naproxen sodium, may be associated with a reversible delay in ovulation [ see Use in Specific Populations ( 8.3 ) ]. Fetal Toxicity Inform pregnant women to avoid use of naproxen sodium and other NSAIDs starting at 30 weeks gestation because of the risk of the premature closing of the fetal ductus arteriosus. If treatment with naproxen sodium is needed for a pregnant woman between about 20 to 30 weeks gestation, advise her that she may need to be monitored for oligohydramnios, if treatment continues for longer than 48 hours [ see Warnings and Precautions ( 5.11) and Use in Specific Populations ( 8.1 ) ]. Avoid Concomitant Use of NSAIDs Inform patients that the concomitant use of naproxen sodium with other NSAIDs or salicylates (e.g., diflunisal, salsalate) is not recommended due to the increased risk of gastrointestinal toxicity, and little or no increase in efficacy [ see Warnings and Precautions ( 5.2 ) and Drug Interactions ( 7 ) ]. Alert patients that NSAIDs may be present in “over the counter” medications for treatment of colds, fever, or insomnia. Use of NSAIDS and Low-Dose Aspirin Inform patients not to use low-dose aspirin concomitantly with naproxen sodium until they talk to their healthcare provider [ see Drug Interactions ( 7 ) ].
