CAREFULLY CONSIDER THE POTENTIAL BENEFITS AND RISKS OF NAPROXEN AND OTHER TREATMENT OPTIONS BEFORE DECIDING TO USE NAPROXEN TABLETS. USE THE LOWEST EFFECTIVE DOSE FOR THE SHORTEST DURATION CONSISTENT WITH INDIVIDUAL PATIENT TREATMENT GOALS (SEE WARNINGS; GASTROINTESTINAL BLEEDING, ULCERATION, AND PERFORATION).
AFTER OBSERVING THE RESPONSE TO INITIAL THERAPY WITH NAPROXEN TABLETS, THE DOSE AND FREQUENCY SHOULD BE ADJUSTED TO SUIT AN INDIVIDUAL PATIENT’S NEEDS.
DIFFERENT DOSE STRENGTHS AND FORMULATIONS (I.E., TABLETS, SUSPENSION) OF THE DRUG ARE NOT NECESSARILY BIOEQUIVALENT. THIS DIFFERENCE SHOULD BE TAKEN INTO CONSIDERATION WHEN CHANGING FORMULATION.
ALTHOUGH NAPROXEN TABLETS, NAPROXEN SUSPENSION, NAPROXEN DELAYED-RELEASED TABLETS, AND NAPROXEN SODIUM TABLETS ALL CIRCULATE IN THE PLASMA AS NAPROXEN, THEY HAVE PHARMACOKINETIC DIFFERENCES THAT MAY AFFECT ONSET OF ACTION. ONSET OF PAIN RELIEF CAN BEGIN 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; HEPATOTOXICITY, AND RENAL TOXICITY AND HYPERKALEMIA, AND PRECAUTIONS; GERIATRIC USE).
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).
RHEUMATOID ARTHRITIS, OSTEOARTHRITIS AND ANKYLOSING SPONDYLITIS
THE RECOMMENDED DOSE IS 250 MG, 375 MG, OR 500 MG TWICE DAILY. 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).
NAPROXEN TABLETS MAY NOT ALLOW FOR THE FLEXIBLE DOSE TITRATION NEEDED IN PEDIATRIC PATIENTS WITH JUVENILE ARTHRITIS. A LIQUID FORMULATION MAY BE MORE APPROPRIATE. IN PEDIATRIC PATIENTS, DOSES OF 5 MG/KG/DAY PRODUCED PLASMA LEVELS OF NAPROXEN SIMILAR TO THOSE SEEN IN ADULTS TAKING 500 MG OF NAPROXEN (SEE CLINICAL PHARMACOLOGY). THE RECOMMENDED TOTAL DAILY DOSE OF NAPROXEN IS APPROXIMATELY 10 MG/KG GIVEN IN 2 DIVIDED DOSES. ONE-HALF OF THE 250 MG TABLET WILL BE NEEDED FOR DOSING LOWER-WEIGHT CHILDREN. DOSING WITH NAPROXEN TABLETS IS NOT APPROPRIATE FOR CHILDREN WEIGHING LESS THAN 25 KILOGRAMS. THE RECOMMENDED TOTAL DAILY DOSE OF NAPROXEN IS APPROXIMATELY 10 MG/KG GIVEN IN 2 DIVIDED DOSES (I.E., 5 MG/KG GIVEN TWICE A DAY). NAPROXEN TABLETS ARE NOT WELL SUITED TO THIS DOSAGE SO USE OF NAPROXEN ORAL SUSPENSION IS RECOMMENDED FOR THIS INDICATION.
MANAGEMENT OF PAIN, PRIMARY DYSMENORRHEA, AND ACUTE TENDONITIS AND BURSITIS
BECAUSE THE SODIUM SALT OF NAPROXEN IS MORE RAPIDLY ABSORBED, NAPROXEN SODIUM IS RECOMMENDED FOR THE MANAGEMENT OF ACUTE PAINFUL CONDITIONS WHEN PROMPT ONSET OF PAIN RELIEF IS DESIRED. NAPROXEN MAY ALSO BE USED. THE RECOMMENDED STARTING DOSE OF NAPROXEN IS 500 MG, FOLLOWED BY 500 MG EVERY 12 HOURS OR 250 MG EVERY 6 TO 8 HOURS AS REQUIRED. THE INITIAL TOTAL DAILY DOSE SHOULD NOT EXCEED 1250 MG OF NAPROXEN.
THE RECOMMENDED STARTING DOSE IS 750 MG OF NAPROXEN FOLLOWED BY 250 MG EVERY 8 HOURS UNTIL THE ATTACK HAS SUBSIDED.
Medication Guide for Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)
Medication Guide for Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)
What is the most important information I should know about medicines called Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)?
NSAIDs can cause serious side effects, including:
Increased risk of a heart attack or stroke that can lead to death. This risk may happen early in treatment and may increase:
o with increasing doses of NSAIDs
o with longer use of NSAIDs
Do not take NSAIDs right before or after a heart surgery called a “coronary artery bypass graft (CABG).”
Avoid taking NSAIDs after a recent heart attack, unless your healthcare provider tells you to. You may have an increased risk of another heart attack if you take NSAIDs after a recent heart attack.
Increased risk of bleeding, ulcers, and tears (perforation) of the esophagus (tube leading from the mouth to the stomach), stomach and intestines:
o any time during use
o without warning symptoms
o that may cause death
The risk of getting an ulcer or bleeding increases with:
o past history of stomach ulcers, or stomach or intestinal bleeding with use of NSAIDs
o taking medicines called “corticosteroids”, “anticoagulants”, “SSRIs”, or “SNRIs”
o increasing doses of NSAIDs o older age
o longer use of NSAIDs o poor health
o smoking o advanced liver disease
o drinking alcohol o bleeding problems
NSAIDs should only be used:
o exactly as prescribed
o at the lowest dose possible for your treatment
o for the shortest time needed
What are NSAIDs?
NSAIDs are used to treat pain and redness, swelling, and heat (inflammation) from medical conditions such as different types of arthritis, menstrual cramps, and other types of short-term pain.
Who should not take NSAIDs?
Do not take NSAIDs:
• if you have had an asthma attack, hives, or other allergic reaction with aspirin or any other NSAIDs.
• right before or after heart bypass surgery.
Before taking NSAIDs, tell your healthcare provider about all of your medical conditions, including if you:
• have liver or kidney problems
• have high blood pressure
• have asthma
• are pregnant or plan to become pregnant. Talk to your healthcare provider if you are considering taking NSAIDs during pregnancy. You should not take NSAIDs after 29 weeks of pregnancy.
• are breastfeeding or plan to breastfeed.
Tell your healthcare provider about all of the medicines you take, including prescription or over-the-counter medicines, vitamins or herbal supplements. NSAIDs and some other medicines can interact with each other and cause serious side effects. Do not start taking any new medicine without talking to your healthcare provider first.
What are the possible side effects of NSAIDs?
NSAIDs can cause serious side effects, including:
See “What is the most important information I should know about medicines called Nonsteroidal Anti-inflammatory Drugs (NSAIDs)”?
• new or worse high blood pressure

These are not all the possible side effects of NSAIDs. For more information, ask your healthcare provider or pharmacist about NSAIDs. Call your doctor for medical advice about side effects. You may report side effects to Marksans at 1-877-376-4271 and/orFDA at 1-800-FDA-1088.
Other information about NSAIDs
Aspirin is an NSAID medicine but it does not increase the chance of a heart attack. Aspirin can cause bleeding in the brain, stomach, and intestines. Aspirin can also cause ulcers in the stomach and intestines.
Some NSAIDs are sold in lower doses without a prescription (over-the-counter). Talk to your healthcare provider before using over-the-counter NSAIDs for more than 10 days.
General information about the safe and effective use of NSAIDs
Medicines are sometimes prescribed for purposes other than those listed in a Medication Guide. Do not use NSAIDs for a condition for which it was not prescribed. Do not give NSAIDs to other people, even if they have the same symptoms that you have. It may harm them.
If you would like more information about NSAIDs, talk with your healthcare provider. You can ask your pharmacist or healthcare provider for information about NSAIDs that is written for health professionals.
