naproxen sodium (OTC)
How does this medication work? What will it do for me?
Naproxen sodium belongs to a group of medications called nonsteroidal anti-inflammatory drugs (NSAIDs). It is used to treat fever and pain caused by inflammation, including pain due to arthritis, muscle aches, sprains, strains, backache, headache, migraine, minor aches, menstrual cramps, minor surgery, toothache, dental extractions, and the common cold. It can also be used to reduce fever.
Naproxen sodium works at the site of pain and in the central nervous system (CNS). It is believed to work by stopping the production of prostaglandins, which cause inflammation.

Allergic reactions: This medication should not be given to people who have had a reaction to acetylsalicylic acid (ASA) that included a runny nose, itchy skin rash, nasal polyps, or shortness of breath and wheezing. If you experience symptoms of a severe allergic reaction (e.g., hives; difficulty breathing; wheezing; swelling of the face, tongue, or throat), get immediate medical attention. If you have a history of asthma, runny nose not caused by the common cold, or nasal polyps, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Blood clotting: This medication may reduce the ability of the blood to clot for some people. If you are taking acetylsalicylic acid (ASA) or blood thinners (e.g., warfarin), discuss with your doctor or pharmacist how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
If you notice any signs of bleeding, such as frequent nosebleeds, unexplained bruising, or black and tarry stools, notify your doctor as soon as possible. Your doctor will order routine blood tests to make sure potential problems are caught early.
Drowsiness/reduced alertness: As with other NSAIDs, naproxen sodium can cause drowsiness, dizziness, blurred vision, and ringing in the ears. Avoid driving and other activities that require alertness and concentration until you determine how this medication affects you.
Heart failure and high blood pressure: NSAIDs such as naproxen sodium can cause fluid retention and edema (swelling). This can lead to high blood pressure or worsening of heart failure. If you have heart failure or high blood pressure, discuss with your doctor or pharmacist how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Ulcers or bleeding in the stomach or intestines: NSAIDs such as naproxen sodium can cause stomach ulcers and bleeding from the stomach. If you have a history of these conditions, discuss with your doctor or pharmacist how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. People with inflammatory bowel disease, such Crohn’s disease or ulcerative colitis or those who have ulcers in the stomach or intestines that are bleeding, should not take this medication.
If you experience symptoms of bleeding in the digestive system, such as black, tarry stools or stomach pain, contact your doctor immediately.
Pregnancy: This medication should not be used during the third trimester (last 3 months) of pregnancy. This medication should not be used during the first and second trimester (first 6 months) of pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
This medication may reduce your ability to become pregnant. Taking this medication while trying to become pregnant is not recommended.
Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are taking naproxen sodium, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children under 12 years of age.
Seniors: Seniors appear to have a higher risk of side effects. If you are over the age of 65, use the lowest effective dosage under close medical supervision. Ask your doctor or pharmacist about all available treatment options that may be right for you.
