Whether it’s a stubborn headache, arthritis, or muscle soreness from a workout, finding effective relief is essential. Many turn to naproxen sodium, a trusted medication known for its long-lasting pain relief. Naproxen sodium belongs to a group of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). These medications work by reducing pain, swelling, and fever. 

Unlike other pain relievers, naproxen sodium provides relief for up to 12 hours, making it a convenient option for those needing all-day or overnight pain management. This article explores naproxen sodium—its uses, benefits, and potential risks.

What Is Naproxen Sodium?

Naproxen sodium is a widely used pain reliever and anti-inflammatory medication. It belongs to a class of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). It helps reduce pain, inflammation, and fever by blocking certain chemicals in the body.

Common over-the-counter (OTC) and prescription brands that contain naproxen sodium include Aleve®, Anaprox®, Naprelan®, and Naprosyn®.

How Does Naproxen Sodium Work?

Naproxen sodium reduces the production of prostaglandins, which helps lower pain and reduce swelling. Prostaglandins are substances that cause inflammation, pain, and fever. When you get injured or have a condition like arthritis, your body produces more prostaglandins, making the affected area swollen and painful. 

More specifically, naproxen targets enzymes called COX-1 and COX-2. These enzymes help produce prostaglandins, so by blocking them, naproxen sodium helps relieve pain and swelling associated with conditions such as arthritis, menstrual cramps, and injuries.  

Uses and Benefits of Naproxen Sodium

Naproxen sodium is used to relieve pain, inflammation, and fever. It has a longer duration of action compared to some other NSAIDs, making it a commonly used option for pain management.

Common Conditions Treated

Naproxen sodium is often used to manage:

  • Acute pain: such as headaches and toothaches
  • Arthritis: including osteoarthritis and rheumatoid arthritis
  • Menstrual cramps: to reduce pain and discomfort
  • Sports injuries: including muscle strains and sprains
  • Post-operative pain

Comparison With Other NSAIDs

Naproxen sodium is one of many NSAIDs, here’s how it compares to other pain relievers:

The effectiveness and side effects of NSAIDs may vary by individual. Consult your healthcare provider for personalized recommendations.

Benefits of Naproxen Sodium

  • Long-lasting relief: Works for up to 12 hours.
  • Widely available: Sold over the counter and by prescription.
  • Cost-effective: Naproxen sodium may be a more affordable option compared to some other pain relievers.

Dosage and Administration

Below are typical dosages for naproxen sodium. 

Recommended Dosages

Dosage varies based on individual needs and medical conditions. 

  • Adults typically take 220-550 mg every 8-12 hours as needed. 
  • The maximum recommended daily dose is 1,375 mg unless directed otherwise by a healthcare provider. 
  • Children under 12 should consult a physician before use.

Factors Affecting Dosage

Considerations that impact dosing include:

  • Weight and age: Higher doses may be needed for adults than children.
  • Medical conditions: People with kidney or heart issues may need lower doses.
  • Other medications: Some drugs interact with naproxen sodium.

Consult your healthcare provider for the most appropriate dose for your needs.

Overdose Risks and Management

Signs of overdose may include:

  • Extreme drowsiness
  • Nausea or vomiting
  • Stomach pain
  • Breathing problems

If an overdose is suspected, seek emergency medical attention or call Poison Control (1-800-222-1222) immediately.

Risks and Side Effects of Naproxen Sodium

Naproxen sodium, like all NSAIDs, carries a risk of gastrointestinal bleeding, cardiovascular events (heart attack, stroke), and kidney damage, particularly with long-term use. The FDA has issued a Black Box Warning regarding these risks. 

Common Side Effects

Most people can take naproxen sodium without serious problems, but some may experience side effects such as:

  • Stomach pain or heartburn
  • Nausea or indigestion
  • Dizziness or drowsiness
  • Headache

Taking naproxen sodium with food or milk can help reduce stomach-related side effects.

Severe Risks

In some cases, naproxen sodium may cause more serious health problems, including:

  • Stomach ulcers or bleeding: Symptoms may include black or bloody stools, vomiting blood, or severe stomach pain.
  • Heart problems: Long-term use can increase the risk of heart attack or stroke.
  • Kidney damage: May cause swelling, tiredness, or changes in urination.
  • Allergic reactions: Symptoms may include rash, swelling, or trouble breathing.

Seek immediate medical help if you experience these or other symptoms, such as chest pain, difficulty breathing, facial swelling, or severe stomach pain.

Drug Interactions

Naproxen sodium may interact with other medications, increasing the risk of side effects. Avoid using naproxen sodium with:

  • Other NSAIDs (like ibuprofen or aspirin): Increases the risk of stomach bleeding.
  • Blood thinners (such as warfarin): May cause excessive bleeding.
  • Certain antidepressants (like SSRIs): May raise the risk of stomach ulcers.
  • Diuretics ("water pills") and some blood pressure medications: May reduce kidney function when taken with naproxen sodium.
  • Alcohol or grapefruit juice without medical guidance

Always check with your healthcare provider or pharmacist before taking naproxen sodium with other medications, alcohol, or grapefruit juice.

When to Consult a Doctor

If you continue to feel pain after several doses, you may need a different treatment. If pain persists beyond a few days despite taking naproxen sodium as directed, consult a healthcare provider to determine if an alternative treatment is needed.

Preexisting Conditions and Use

Naproxen sodium may not be safe for people with heart disease, kidney or liver problems, or ulcers, or stomach bleeding.  Its use is contraindicated in people with:

  • Hypersensitivity to NSAID medications.
  • Asthma that is triggered by the use of aspirin or NSAIDs.
  • Pregnancy: Naproxen sodium and other NSAIDS should not be used after 30 weeks gestation due to the risk of fetal guidelines.

Practical Tips for Safe Use

Store in a cool, dry place away from heat and moisture. Keep out of reach of children and pets.

Monitoring for Side Effects

Keep track of any side effects, including stomach pain, dizziness, or swelling. If you experience side effects, stop using and contact your healthcare provider.

Alternatives to Naproxen Sodium

If naproxen sodium isn’t right for you, consider using:

  • Other NSAIDs: Like ibuprofen or aspirin.
  • Acetaminophen: A better choice for people with stomach problems.
  • Natural remedies: Such as heat therapy or turmeric for mild pain relief.

Your healthcare provider can recommend alternatives based on your needs.

FAQs

Q: Can I take naproxen sodium daily?
A
: Only if your healthcare provider says it’s safe. Taking naproxen sodium every day for a long time can increase the risk of stomach ulcers, kidney problems, and heart issues. If you need pain relief often, talk to a doctor about options.

Q: Can I take it with food?
A
: Yes. Taking naproxen sodium with food or milk helps protect your stomach and reduces the chances of heartburn, nausea, or irritation.

Q: Is naproxen sodium better than ibuprofen?
A
: It depends on your pain. Naproxen sodium lasts longer (up to 12 hours), making it better for ongoing pain like arthritis or menstrual cramps. Ibuprofen works faster but lasts only 4-6 hours, so it’s better for quick relief like headaches or minor injuries.
