- Risk may increase with duration of use
- Patients with existing cardiovascular disease or risk factors for such disease may be at greater risk
- NSAIDs are contraindicated for perioperative pain in setting of coronary artery bypass graft (CABG) surgery
Gastrointestinal risk
- NSAIDs increase risk of serious GI adverse events, including bleeding, ulceration, and gastric or intestinal perforation, which can be fatal
- GI adverse events may occur at any time during use and without warning symptoms
- Elderly patients are at greater risk for serious GI events
Contraindications
Absolute: Aspirin allergy; perioperative pain in setting of coronary artery bypass graft (CABG) surgery
Relative: Bleeding disorders, delayed esophageal transit, hepatic disease, peptic ulcer, renal impairment, stomatitis, late pregnancy (may cause premature closure of ductus arteriosus)
Cautions
Use caution in congestive heart failure (CHF), hypertension, renal/hepatic impairment, or aspirin sensitive asthma
May increase risk of aseptic meningitis, especially in patients with systemic lupus erythematosis and mixed connective tissue disorders
Prolonged use may increase risk of adverse cardiovascular events
May cause anaphylactoid reactions, even in patients with no prior exposure to NSAIDs
Long-term administration of NSAIDs may result in renal papillary necrosis and other renal injury; patients at greatest risk include elderly individuals, those with impaired renal function, hypovolemia, heart failure, liver dysfunction, or salt depletion, and those taking diuretics, angiotensin-converting enzyme inhibitors, or angiotensin-receptor blockers
May cause drowsiness, dizziness, and blurred vision
Platelet aggregation and adhesion may be decreased; may prolong bleeding time; monitor closely patients with coagulation disorders
Patient should ask a doctor or pharmacist, before taking this medication, if under a doctor's care for any serious condition, taking aspirin for heart attack or stroke (drug may decrease benefit of aspirin), or if taking any other drug
May increase risk of hyperkalemia in the elderly, renal disease, or diabetics, especially when used concomitantly with drugs that increase hyperkalemia
May cause serious skin reactions including exfoliative dermatitis, toxic epidermal syndrome, Stevens-Johnson syndrome, and toxic epidermal necrolysis; discontinue therapy at first sign of skin rash
May cause new-onset of hypertension; monitor blood pressure closely throughout therapy
OTC use not for children <12 years
Withhold for at least 4-6 half-lives prior to surgery or dental procedure
Heart failure risk
- NSAIDS have the potential to trigger HF by prostaglandin inhibition that leads to sodium and water retention, increased systemic vascular resistance, and blunted response to diuretics
- NSAIDS should be avoided or withdrawn whenever possible
- Heart failure: risk is higher if you administer more than directed or for longer than directed
- AHA/ACC Heart Failure Guidelines; Circulation. 2016; 134
Drug reaction with eosinophilia and systemic symptoms
- Drug Reaction reported in patients taking NSAIDs; some of these events have been fatal or life-threatening; DRESS typically, although not exclusively, presents with fever, rash, lymphadenopathy, and/or facial swelling
- Other clinical manifestations may include hepatitis, nephritis, hematological abnormalities, myocarditis, or myositis; sometimes symptoms of DRESS may resemble an acute viral infection
- Eosinophilia is often present; because this disorder is variable in its presentation, other organ systems not noted here may be involved
- Early manifestations of hypersensitivity, such as fever or lymphadenopathy, may be present even though rash is not evident; if such signs or symptoms are present, discontinue therapy and evaluate the patient immediately
Pregnancy & Lactation
Pregnancy
When self-medicating, if pregnant or breast-feeding, ask a health professional before use; it is especially important not to take medication at 20 weeks or later in pregnancy unless definitely directed to do so by a doctor because it may cause problems in unborn child or complications during delivery
Use of NSAIDs can cause premature closure of fetal ductus arteriosus and fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment
Because of these risks, limit dose and duration of use between about 20 and 30 weeks of gestation, and avoid use at about 30 weeks of gestation and later in pregnancy
Use of NSAIDs at about 30 weeks gestation or later in pregnancy increases risk of premature closure of fetal ductus arteriosus
If an NSAID is necessary at about 20 weeks gestation or later in pregnancy, limit use to lowest effective dose and shortest duration possible; if treatment extends beyond 48 hours, consider monitoring with ultrasound for oligohydramnios; if oligohydramnios occurs, discontinue therapy and follow up according to clinical practice
Data from observational studies regarding other potential embryofetal risks of NSAID use in women in the first or second trimesters of pregnancy are inconclusive
Animal data
- In animal reproduction studies in rats, rabbits, and mice no evidence of teratogenicity or fetal harm when naproxen was administered during the period of organogenesis at doses 0.13, 0.26, and 0.6 times maximum recommended human daily dose of 1500 mg/day, respectively
- Based on animal data, prostaglandins have been shown to have an important role in endometrial vascular permeability, blastocyst implantation, and decidualization
- In animal studies, administration of prostaglandin synthesis inhibitors resulted in increased pre-and post-implantation loss; prostaglandins also have been shown to have an important role in fetal kidney development; in published animal studies, prostaglandin synthesis inhibitors have been reported to impair kidney development when administered at clinically relevant doses
- There are no studies on effects of therapy during labor or delivery; in animal studies, NSAIDS inhibit prostaglandin synthesis, cause delayed parturition, and increase incidence of stillbirth
Lactation
Based on available published clinical data, drug may be present in human milk; developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed infant from drug or from underlying maternal condition
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

NAPROXEN SUSPENSION - ORAL
(nah-PROX-en)
COMMON BRAND NAME(S): Naprosyn
WARNING: Nonsteroidal anti-inflammatory drugs (including naproxen) may rarely increase the risk for a heart attack or stroke. This effect can happen at any time while taking this drug but is more likely if you take it for a long time. The risk may be greater in older adults or if you have heart disease or increased risk for heart disease (for example, due to smoking, family history of heart disease, or conditions such as high blood pressure or diabetes). Do not take this drug right before or after heart bypass surgery (CABG).This drug may rarely cause serious (rarely fatal) bleeding from the stomach or intestines. This effect can occur without warning at any time while taking this drug. Older adults may be at higher risk for this effect.Stop taking naproxen and get medical help right away if you notice any of these rare but serious side effects: stomach/abdominal pain that doesn't go away, black/tarry stools, vomit that looks like coffee grounds, chest/jaw/left arm pain, shortness of breath, unusual sweating, confusion, weakness on one side of the body, trouble speaking, sudden vision changes.Talk to your doctor or pharmacist about the benefits and risks of taking this drug.
USES: Naproxen is used to relieve pain from various conditions such as headaches, muscle aches, tendonitis, dental pain, and menstrual cramps. It also reduces pain, swelling, and joint stiffness caused by arthritis, bursitis, and gout attacks. This medication is known as a nonsteroidal anti-inflammatory drug (NSAID). It works by blocking your body's production of certain natural substances that cause inflammation.If you are treating a chronic condition such as arthritis, ask your doctor about non-drug treatments and/or using other medications to treat your pain. See also Warning section.
HOW TO USE: Read the Medication Guide provided by your pharmacist before you start using naproxen and each time you get a refill. If you have any questions, ask your doctor or pharmacist.Shake the bottle well before each dose. Carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose. Take this medication by mouth as directed by your doctor, usually 2 times a day. To prevent stomach upset, take this medication with food, milk, or an antacid.The dosage is based on your medical condition and response to treatment. In children, the dosage is also based on weight. To reduce your risk of stomach bleeding and other side effects, take this medication at the lowest effective dose for the shortest possible time. Do not increase your dose or take this drug more often than directed. For ongoing conditions such as arthritis, continue taking this medication as directed by your doctor.For certain conditions (such as arthritis), it may take up to two weeks of taking this drug regularly until you get the full benefit.If you are taking this drug "as needed" (not on a regular schedule), remember that pain medications work best if they are used as the first signs of pain occur. If you wait until the pain has worsened, the medication may not work as well.Tell your doctor if your condition does not improve or if it worsens.
SIDE EFFECTS: See also Warning section.Upset stomach, nausea, heartburn, headache, drowsiness, or dizziness may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects.

PRECAUTIONS: Before taking naproxen, tell your doctor or pharmacist if you are allergic to it; or to aspirin or other NSAIDs (such as ibuprofen, celecoxib); or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.Before taking this medication, tell your doctor or pharmacist your medical history, especially of: asthma (including a history of worsening breathing after taking aspirin or other NSAIDs), blood disorders (such as anemia, bleeding/clotting problems), growths in the nose (nasal polyps), heart disease (such as previous heart attack), high blood pressure, liver disease, stroke, throat/stomach/intestinal problems (such as bleeding, heartburn, ulcers).Kidney problems can sometimes occur with the use of NSAID medications, including naproxen. Problems are more likely to occur if you are dehydrated, have heart failure or kidney disease, are an older adult, or if you take certain medications (see also Drug Interactions section). Drink plenty of fluids as directed by your doctor to prevent dehydration and tell your doctor right away if you have a change in the amount of urine.This drug may make you dizzy or drowsy. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Talk to your doctor if you are using marijuana (cannabis).This medicine may cause stomach bleeding. Daily use of alcohol and tobacco, especially when combined with this medicine, may increase your risk for stomach bleeding. Limit alcohol and stop smoking. Consult your doctor or pharmacist for more information.This medication may make you more sensitive to the sun. Limit your time in the sun. Avoid tanning booths and sunlamps. Use sunscreen and wear protective clothing when outdoors. Tell your doctor right away if you get sunburned or have skin blisters/redness.This medication contains salt (sodium). Tell your doctor if you are on a salt-restricted diet.Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).Older adults may be at greater risk for stomach/intestinal bleeding, kidney problems, heart attack, and stroke while using this drug.Before using this medication, women of childbearing age should talk with their doctor(s) about the benefits and risks.

DRUG INTERACTIONS: Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.Products that may interact with this drug include: aliskiren, ACE inhibitors (such as captopril, lisinopril), angiotensin II receptor blockers (such as losartan, valsartan), cidofovir, corticosteroids (such as prednisone), lithium, "water pills" (diuretics such as furosemide).This medication may increase the risk of bleeding when taken with other drugs that also may cause bleeding. Examples include anti-platelet drugs such as clopidogrel, "blood thinners" such as dabigatran/enoxaparin/warfarin, among others.Check all prescription and nonprescription medicine labels carefully since many medications contain pain relievers/fever reducers (aspirin, NSAIDs such as celecoxib, ibuprofen, or ketorolac). These drugs are similar to naproxen and may increase your risk of side effects if taken together. However, if your doctor has directed you to take low-dose aspirin to prevent heart attack or stroke (usually 81-162 milligrams a day), you should continue taking the aspirin unless your doctor instructs you otherwise. Daily use of naproxen may decrease aspirin's ability to prevent heart attack/stroke. Talk with your doctor about the risks and benefits. Ask about other medications that can be used to treat pain/fever.This medication can affect the results of certain laboratory tests, possibly causing false test results. Make sure laboratory personnel and all your doctors know you use this drug.
