Before taking any over-the-counter drug, read all directions on the packaging. If your doctor has prescribed naproxen, read the Medication Guide issued by your chemist before starting and when getting refills. If you have any questions, talk to your doctor or chemist.

Take this medication by mouth as directed by your doctor, usually 2 or 3 times a day with a full glass of water (8 ounces/240 milliliters). Do not lie down for at least 10 minutes after taking this drug. To prevent stomach upset, take this medication with food, milk, or an antacid.

The dosage is determined by your medical condition and reaction to treatment. To limit the risk of stomach bleeding and other adverse effects, take this drug at the lowest effective dose for the shortest duration. Do not exceed your doctor’s or the package label’s recommended dose or frequency of use. Continue to take this medication as prescribed by your doctor for continuing diseases like arthritis.

For certain conditions (such as arthritis), it may take up to two weeks of taking this drug regularly until you get the full benefit.

When taking this prescription “as needed” (not on a regular basis), it’s important to remember that pain medications are most effective when given at the first signs of pain. If you wait until the pain worsens, the medication may not be as effective.

If your ailment persists or worsens, or you suspect you have a significant medical concern, seek medical attention immediately. If you are taking a nonprescription medicine to treat a fever, contact your doctor right away if it worsens or lasts more than three days.
