Naproxen is used to relieve pain and swelling (inflammation) from various conditions. It is used to treat headaches, muscle aches, backaches, tendonitis, dental pain, and menstrual cramps. It also reduces pain, swelling, and joint stiffness caused by arthritis, bursitis, and gout attacks. Reducing these symptoms helps you do more of your normal daily activities. This medication is known as a nonsteroidal anti-inflammatory drug (NSAID).
How to use Naproxen Oral
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 regarding the information, consult your doctor or pharmacist.
Take this medication by mouth with a full glass of water (8 ounces or 240 milliliters) unless your doctor directs you otherwise. Do not lie down for at least 30 minutes after taking this drug. To prevent stomach upset, take this medication with food, milk, or an antacid.
Dosage is based on your medical condition and response to therapy. Do not take more than 1,500 milligrams of naproxen (equal to 1,650 milligrams of naproxen sodium) per day. To minimize side effect risks (e.g., stomach bleeding), use this medication at the lowest effective dose for the shortest possible length of time. Do not increase your dose or take it more often than prescribed. For ongoing conditions such as arthritis, continue taking it as directed by your doctor. Discuss the risks and benefits with your doctor or pharmacist.
In certain conditions (e.g., arthritis), it may take up to 2 weeks of regular use before the full benefits of this drug take effect.
If you are taking this drug on an “as needed” basis (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 significantly worsened, the medicine may not work as well.
If you use this medication for migraine headache, and the pain is not relieved or worsens after the first dose, tell your doctor immediately.
Inform your doctor if your condition worsens.
