How should I take Naprosyn?
Use Naprosyn 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 Naprosyn 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 Naprosyn 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 Naprosyn.
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 this medicine
Naprosyn may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using Naprosyn, especially in older adults.
You should not use Naprosyn if you are allergic to naproxen, 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;
liver or kidney disease; or
Taking Naprosyn 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.
Naprosyn is not approved for use by anyone younger than 2 years old. Do not give this medicine to a child without medical advice.
What happens if I miss a dose?
Since Naprosyn 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 Naprosyn?
Avoid drinking alcohol. It may increase your risk of stomach bleeding.
Avoid taking aspirin while you are taking Naprosyn.
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 other drugs will affect Naprosyn?
Ask your doctor before using Naprosyn 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 Naprosyn if you are also using any of the following drugs:
phenytoin or similar seizure medications;
warfarin (Coumadin, Jantoven) or similar blood thinners;
a diuretic or “water pill”;
heart or blood pressure medication; or
insulin or oral diabetes medicine.
