Naproxen is employed to alleviate pain associated with various conditions, including headaches, muscle aches, tendonitis, dental pain, and menstrual cramps. Additionally, it mitigates pain, swelling, and joint stiffness resulting from arthritis, bursitis, and gout attacks. This medication is categorized as a nonsteroidal anti-inflammatory drug (NSAID), functioning by inhibiting the body's production of specific natural substances that contribute to inflammation.

If you are managing a persistent condition like arthritis, it is advisable to consult your doctor regarding non-pharmaceutical treatments or the use of alternative medications for pain management. Always check the ingredients listed on the label, even if you have used the product previously, as the manufacturer may have modified them. Furthermore, products with similar names might contain distinct ingredients designed for different purposes, and using the wrong product may pose potential harm.

How to use Flanax

If you are using the over-the-counter version of this product, carefully read all the instructions provided on the product packaging before taking the medication. In case your doctor has prescribed this medication, refer to the Medication Guide supplied by your pharmacist before initiating naproxen and each time you receive a refill. Any inquiries you may have should be directed to your doctor or pharmacist.

Take this medication orally as directed by your doctor, typically 2 or 3 times daily, accompanied by a full glass of water (8 ounces/240 milliliters). Refrain from lying down for at least 10 minutes after ingesting this drug. To prevent potential stomach upset, consume this medication with food, milk, or an antacid.

The prescribed dosage is contingent upon your medical condition and response to the treatment. To minimize the risk of stomach bleeding and other side effects, take this medication at the lowest effective dose for the shortest duration possible. Do not escalate your dosage or take this medication more frequently than advised by your doctor or indicated on the package label. For persistent conditions such as arthritis, adhere to the prescribed regimen outlined by your doctor.

For specific conditions like arthritis, it might take up to two weeks of consistent use of this drug before experiencing the full therapeutic benefits.

If you are using this drug on an "as-needed" basis (not on a regular schedule), remember that pain medications are most effective when taken at the first signs of pain. Delaying until the pain intensifies may result in reduced effectiveness of the medication.

If your condition persists, worsens, or if you suspect a serious medical issue, seek immediate medical attention. If you are utilizing the nonprescription product to address fever, consult your doctor promptly if the fever worsens or lasts more than 3 days.

It's essential to monitor your blood pressure regularly, as this medication may elevate it. If you observe high blood pressure readings, notify your doctor.

Although rare, this drug may lead to serious, potentially fatal liver disease. If you notice symptoms of liver damage, including persistent nausea/vomiting, loss of appetite, stomach/abdominal pain, yellowing of the eyes/skin, or dark urine, seek immediate medical attention.

Nonsteroidal anti-inflammatory drugs (including naproxen) may, on rare occasions, increase the risk of a heart attack or stroke. This risk exists throughout the course of taking the drug but is more likely if the medication is used for an extended period.

The likelihood of this risk may be higher in older adults or individuals with pre-existing heart conditions or elevated risk factors for heart disease, such as smoking, a family history of heart disease, or conditions like high blood pressure or diabetes. It is important to avoid taking this drug immediately before or after heart bypass surgery (CABG).

There is a rare but serious risk of significant bleeding from the stomach or intestines associated with this drug. This adverse effect can occur suddenly and without warning at any point during the drug's use, with older adults potentially being at a higher risk.

If any of the following rare but serious side effects are observed, cease taking naproxen and seek immediate medical assistance: persistent stomach or abdominal pain, black or tarry stools, vomiting that resembles coffee grounds, chest/jaw/left arm pain, shortness of breath, unusual sweating, confusion, weakness on one side of the body, difficulty speaking, or sudden changes in vision.

It is advisable to discuss with your doctor or pharmacist the potential benefits and risks of taking this drug in your specific case.

Acetaminophen is not an NSAID, but it is a common over-the-counter pain reliever. It is used for reducing pain and fever. It works differently from NSAIDs and is less likely to cause stomach irritation, but it doesn't have the same anti-inflammatory effects.


In the event of an overdose with serious symptoms such as loss of consciousness or difficulty breathing, immediately call 911. Otherwise, promptly contact a poison control center. US residents can reach their local poison control center at 1-800-222-1222, while Canada residents should call a provincial poison control center.
