What is Naproxen?

Naproxen is a nonsteroidal anti-inflammatory drug (NSAID). It works by reducing hormones that cause inflammation and pain in the body.

Naproxen is used to treat pain or inflammation caused by conditions such as arthritis, ankylosing spondylitis, tendinitis, bursitis, gout, or menstrual cramps. It can also be used to treat acute pain caused by other conditions not listed in this medication guide.

The delayed-release or extended-release tablets are slower-acting forms of naproxen that are used only for treating chronic conditions such as arthritis or ankylosing spondylitis. These forms will not work fast enough to treat acute pain.

Naproxen is also available in combination with other medications under the following brand names: Aleve PM, Aleve-D Sinus and Cold, Treximet, and Vimovo

Warnings

You should not use naproxen if you have a history of allergic reaction to aspirin or other NSAID (nonsteroidal anti-inflammatory drug).

Naproxen can increase your risk of fatal heart attack or stroke, especially if you use it long term or take high doses, or if you have heart disease. Even people without heart disease or risk factors could have a stroke or heart attack while taking this medicine.

Do not use this medicine just before or after heart bypass surgery (coronary artery bypass graft, or CABG).

Get emergency medical help if you have swelling of the face or throat, chest pain, weakness, shortness of breath, slurred speech, or problems with vision or balance. Stop taking naproxen and notify your physician if you notice stomach pain, tiredness or weakness, yellow skin or eyes, nausea, vomiting, bloody or black and sticky bowel movements, skin rash, unexplained weight loss or weight gain, or swelling of the hands and feet.

Naproxen may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using this medicine, especially in older adults.

How should I take Naproxen

Prescription naproxen comes as a regular tablet, a delayed-release (a tablet that releases the medication in the intestine to prevent damage to the stomach) tablet, an extended-release (long-acting) tablet, and a suspension (liquid) to take by mouth. The extended-release tablets are usually taken once a day. The tablets, delayed-release tablets, and suspension are usually taken twice a day for arthritis. The tablets and suspension are usually taken every 8 hours for gout, and every 6 to 8 hours as needed for pain. If you are taking naproxen on a regular basis, you should take it at the same time(s) every day.

Nonprescription naproxen comes as tablet, a capsule, and a gel capsule to take by mouth. It is usually taken with a full glass of water every 8 to 12 hours as needed. Nonprescription naproxen may be taken with food or milk to prevent nausea.

Follow the directions on the package or prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take naproxen exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor or written on the package.

If you are taking the suspension, gently shake the suspension well before each use to mix the medication evenly. Use an oral syringe or measuring cup provided by your pharmacist to measure the correct amount of liquid needed for your dose.

Swallow the delayed-release tablets and extended release tablets whole; do not split, chew, or crush them.

If you are taking naproxen to relieve the symptoms of arthritis, your symptoms may begin to improve within 1 week. It may take 2 weeks or longer for you to feel the full benefit of the medication.

Stop taking nonprescription naproxen and call your doctor if your symptoms get worse, you develop new or unexpected symptoms, the part of your body that was painful becomes red or swollen, your pain lasts for more than 10 days, or your fever lasts for more than 3 days.

Dosing information

Use naproxen exactly as directed on the label, or as prescribed by your doctor. Do not take this medicine in larger amounts or for longer than recommended. Use the lowest dose that is effective in treating your condition.

Shake the oral suspension (liquid) well just before you measure a dose. Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.

If you change brands, strengths, or forms of this medicine, your dosage needs may change. Ask your pharmacist if you have any questions about the kind of naproxen you are using.

If a child is using this medicine, tell your doctor if the child has any changes in weight. Doses are based on weight in children, and any changes may affect your child's dose.

If you use this medicine long-term, you may need frequent medical tests.

This medicine can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using naproxen.

Store at room temperature away from moisture, heat, and light. Keep the bottle tightly closed when not in use.

Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.

Before Taking

Naproxen may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using this medicine, especially in older adults.

You should not use naproxen if you are allergic to it, or if you have ever had an asthma attack or severe allergic reaction after taking aspirin or an NSAID.

Ask a doctor before giving naproxen to a child younger than 12 years old.

Ask a doctor or pharmacist if it is safe for you to use this medicine if you have:

  • heart disease, high blood pressure, high cholesterol, diabetes, or if you smoke;

  • a history of heart attack, stroke, or blood clot;

  • a history of stomach ulcers or bleeding;

  • asthma;

  • liver or kidney disease;

  • fluid retention: or

  • if you take aspirin to prevent heart attack or stroke.

If you are pregnant, you should not take naproxen unless your doctor tells you to. Taking a NSAID during the last 20 weeks of pregnancy can cause serious heart or kidney problems in the unborn baby and possible complications with your pregnancy.

It may not be safe to breastfeed while using naproxen. Ask your doctor about any risk.

Naproxen is not approved for use by anyone younger than 2 years old. Do not give this medicine to a child without medical advice.

Naproxen pregnancy and breastfeeding warnings (more detail)

What happens if I miss a dose?

Since naproxen is sometimes used only when needed, you may not be on a dosing schedule. If you are on a schedule, use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

What should I know about storage and disposal of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

What special dietary instructions should I follow?

Unless your doctor tells you otherwise, continue your normal diet.

What should I avoid while using Naproxen?

Avoid drinking alcohol. It may increase your risk of stomach bleeding.

Avoid taking aspirin or other NSAIDs unless your doctor tells you to.

Ask your doctor before taking any other medication for pain, arthritis, fever, or swelling. Many medicines available over the counter contain aspirin, salicylates, or other medicines similar to naproxen (such as ibuprofen or ketoprofen). Taking certain products together can cause you to get too much of this type of medication.

Ask your doctor before using an antacid, and use only the type your doctor recommends. Some antacids can make it harder for your body to absorb naproxen.

Naproxen side effects

Get emergency medical help if you have signs of an allergic reaction to naproxen (runny or stuffy nose, wheezing or trouble breathing, hives, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling).

Stop using naproxen and seek medical treatment if you have a serious drug reaction that can affect many parts of your body. Symptoms may include skin rash, fever, swollen glands, muscle aches, severe weakness, unusual bruising, or yellowing of your skin or eyes.

Get emergency medical help if you have signs of a heart attack or stroke: chest pain spreading to your jaw or shoulder, sudden numbness or weakness on one side of the body, slurred speech, feeling short of breath.

Stop using naproxen and call your doctor at once if you have:

  • shortness of breath (even with mild exertion);

  • swelling or rapid weight gain;

  • the first sign of any skin rash, no matter how mild;

  • signs of stomach bleeding - bloody or tarry stools, coughing up blood or vomit that looks like coffee grounds;

  • liver problems - nausea, upper stomach pain, itching, tired feeling, flu-like symptoms, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes);

  • kidney problems - little or no urinating, painful or difficult urination, swelling in your feet or ankles, feeling tired or short of breath;

  • low red blood cells (anemia) - pale skin, feeling light-headed or short of breath, rapid heart rate, trouble concentrating; or

  • severe skin reaction - fever, sore throat, swelling in your face or tongue, burning in your eyes, skin pain followed by a red or purple skin rash that spreads (especially in the face or upper body) and causes blistering and peeling.

Common naproxen side effects may include:

  • indigestion, heartburn, stomach pain, nausea;

  • headache, dizziness, drowsiness;

What other drugs will affect Naproxen?

Ask your doctor before using naproxen if you take an antidepressant such as citalopram, escitalopram, fluoxetine (Prozac), fluvoxamine, paroxetine, sertraline (Zoloft), trazodone, or vilazodone. Taking any of these medicines with an NSAID may cause you to bruise or bleed easily.

Ask a doctor or pharmacist if it is safe for you to use this medicine if you are also using any of the following drugs:

  • cholestyramine;

  • cyclosporine;

  • digoxin;

  • lithium;

  • methotrexate;

  • pemetrexed;

  • phenytoin or similar seizure medications;

  • probenecid;

  • warfarin (Coumadin, Jantoven) or similar blood thinners;

  • a diuretic or "water pill";

  • heart or blood pressure medication; or

  • insulin or oral diabetes medicine.

This list is not complete. Other drugs may interact with naproxen, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are listed in this medication guide.

What other information should I know?

Before having any laboratory test, tell your doctor and the laboratory personnel that you are taking naproxen.

If you are taking prescription naproxen, do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.

What to Expect

You should start feeling better about one hour after you take naproxen. If you’re taking this medicine twice a day regularly, it might take up to three days for it to work properly.

Depending on your condition, you may take naproxen for only a day or two. But in some cases, it’s used as a long-term treatment.

The extended-release tablets act more slowly and are typically used for chronic conditions. Other forms of naproxen are more suitable for acute pain.

Additional Dosage Information

Your dosage will depend on the formulation you use, your medical condition, the severity of your pain, your age, and other factors.

Doctors may suggest a lower dose for elderly people or those with liver or kidney problems.

Secondary Uses

Naproxen is used for numerous medical conditions. Your doctor may recommend it for conditions that aren’t listed in this medical guide.
