Aleve: Uses, Dosage, Side Effects, Safety, and Frequently Asked Questions
Aleve: Everything You Need to Know
Aleve is an over-the-counter (OTC) pain reliever and fever reducer that contains naproxen sodium, a nonsteroidal anti-inflammatory drug (NSAID). It is commonly used to relieve pain, reduce inflammation, and lower fever in adults and children who meet the approved age requirements.
Aleve is widely used for temporary relief of common aches and pains, including headaches, muscle aches, arthritis pain, back pain, menstrual cramps, toothaches, and minor injuries. Because it provides longer-lasting pain relief than some other OTC pain medications, many people take it for conditions requiring extended symptom control.
This guide explains how Aleve works, its approved uses, dosage recommendations, possible side effects, safety precautions, and answers to frequently asked questions.
What Is Aleve?

Aleve is a brand-name medication containing naproxen sodium, an NSAID that helps reduce pain, inflammation, and fever.
Unlike some pain relievers that primarily reduce pain and fever, NSAIDs also decrease inflammation by blocking enzymes called cyclooxygenase (COX-1 and COX-2), which are involved in the production of prostaglandins—substances that contribute to pain and swelling.
Common Uses of Aleve
Aleve is commonly used for the temporary relief of:
- Headaches
- Muscle aches
- Back pain
- Toothaches
- Menstrual cramps
- Minor arthritis pain
- Joint pain
- Tendon and ligament injuries
- Minor aches associated with the common cold
- Fever
Healthcare professionals may also recommend naproxen for other conditions depending on an individual’s medical needs.
How Does Aleve Work?
Aleve reduces pain and inflammation by decreasing the production of prostaglandins.
This may help:
- Relieve pain
- Reduce swelling
- Improve joint mobility
- Lower fever
- Ease stiffness associated with inflammatory conditions
Its effects generally last longer than many other over-the-counter pain relievers, allowing for less frequent dosing in many adults.
