Warnings
This drug may infrequently cause serious (rarely fatal) bleeding from the stomach or intestines. This side effect can occur without warning at any time during treatment with naproxen. The elderly are at increased risk for serious stomach/intestinal bleeding.
Drugs related to naproxen have rarely caused blood clots to form, resulting in serious (possibly fatal) heart attacks and strokes. This medication might also rarely cause similar problems. The risk of these serious side effects may increase if you have heart disease and with longer use of this medication. Talk to your doctor or pharmacist about the benefits and risks of treatment, as well as other possible medication choices.
Stop taking naproxen and seek immediate medical attention if you notice any of the following rare but very serious side effects: black stools, persistent stomach/abdominal pain, vomit that looks like coffee grounds, chest pain, shortness of breath, weakness on one side of the body, sudden vision changes, slurred speech.
This medication should not be used right before or after heart bypass surgery.
Uses
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 Naprosyn 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.

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.
