Safety and Side Effects
All medicines in the NSAID class, including naproxen, work by blocking the formation of chemicals in the body known asprostaglandins.Prostaglandins contribute to the effects of inflammation, including swelling, fever, and pain.
Some of the common side effects include:
- Heartburn
- Stomach pain or nausea
- Constipation
- Diarrhea
- Gas
- Headache
- Dizziness
- Drowsiness
- Difficulty sleeping
- Bruising
- Itching
- Ringing in your ears (tinnitus)
Naproxen is usually safe, but it has beenassociated with severe and even fatal side effects. These include GI tract, kidney, and heart complications.
Since the side effects of this drug can be pretty serious, you should only take Aleve under the guidance of your doctor. In addition, it’s best to take no more than the recommended dosage for the shortest time necessary.
Allergic Reaction
This drug has the potential to cause an allergic reaction. This kind of reaction may show up as:
- Hives
- Facial swelling
- Asthma
- Skin rash
- Blisters
- Shock
If any of these symptoms occur, stop taking naproxen and seek emergency medical attention.
Stomach Bleeding
Prostaglandins naturally help protect your stomach from damage. Therefore, when Aleve reduces your prostaglandin production, it can cause stomach bleeding.
Signs and symptoms of stomach bleeding include:
- Severe stomach pain
- Black, tarry stools
- Bloody stools
- Vomiting blood
Seek immediate medical attention if you experience any of these effects.

These risks include:
- Elevated blood pressure
- Heart attack
- Heart failure
- Stroke
You can have these effects even if you only use NSAIDs for a few weeks. Taking higher doses for more extended periods may increase your risk.
That said, a 2016 Danish study found an association between short-term ibuprofen or diclofenactreatment and cardiovascular events. However, it did not identify a link specifically between naproxen and such events.
Symptoms to Watch For
Symptoms that may indicate cardiovascular side effects that require immediate attention include:
- Fluid retention
- Chest pain
- Weakness
- Shortness of breath

If you have any of these, stop taking naproxenand seek immediate medical attention.
