What is the most important information I should know about naproxen?
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. Do not use this medicine just before or after heart bypass surgery (coronary artery bypass graft, or CABG).
Naproxen may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using naproxen, especially in older adults.
What is naproxen?
Naproxen is a nonsteroidal anti-inflammatory drug (NSAID). Naproxen 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.
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 of naproxen will not work fast enough to treat acute pain.
Naproxen may also be used for purposes not listed in this medication guide.
What should I discuss with my healthcare provider before taking naproxen?
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).
Naproxen may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using naproxen, 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 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; or
- fluid retention.
Taking naproxen during the last 3 months of pregnancy may harm the unborn baby. Ask a doctor before using this medicine if you are pregnant. Naproxen may interfere with ovulation, causing temporary infertility.
Naproxen can pass into breast milk and may cause side effects in the nursing baby. You should not breast-feed while using this medicine.
Naproxen is not approved for use by anyone younger than 2 years old. Do not give this medicine to a child without medical advice.
How should I take naproxen?
Use 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.
Do not crush, chew, or break a naproxen tablet. Swallow it whole.
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 naproxen, 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. Naproxen doses are based on weight in children, and any changes may affect your child's dose.
If you use naproxen 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.
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 avoid while taking naproxen?
Avoid drinking alcohol. It may increase your risk of stomach bleeding.
Avoid taking aspirin while you are taking naproxen.
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.
What are the possible side effects of naproxen?
Get emergency medical help if you have signs of an allergic reaction: sneezing, runny or stuffy nose; wheezing or trouble breathing; hives; swelling of your face, lips, tongue, or throat.
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.
