Naproxen

Pain and inflammation

Also known as Aleve

Naproxen is an NSAID, in the same family as ibuprofen, but each dose lasts longer — which makes it handy for all-day aches like back pain, arthritis flares, or period cramps. It works by turning down the chemicals that cause pain and swelling. Because it stays in your body longer, it's extra important not to take doses too close together or stack it with other NSAIDs.

How to take it

When

As needed. Doses are spaced further apart than ibuprofen — follow the label timing.

Food

Take with food or a glass of milk to protect your stomach.

Avoid

Don't take it alongside ibuprofen, aspirin products, or other NSAIDs. Limit alcohol.

Good to know

Talk to your doctor before regular use if you take blood thinners or blood pressure medicine, or have heart or kidney issues.

Missed a dose?

Naproxen is usually taken as needed, so there's typically no missed dose to worry about. If you're on a schedule from your doctor, take it when you remember unless the next dose is coming up soon. Never double up.

Common side effects

Heartburn or upset stomach
Nausea
Drowsiness or dizziness
Headache
Ringing in the ears

Call a doctor if

Black, tarry stools or vomit that looks like coffee grounds — possible stomach bleeding. Get help now.
Chest pain, shortness of breath, sudden weakness, or slurred speech — call emergency services. NSAIDs can raise heart attack and stroke risk, especially with long-term use.
Hives, swelling of the face or throat, or trouble breathing — serious allergic reaction. Call emergency services.
Peeing much less than usual or new swelling in your ankles — call your doctor right away.
Severe or lasting stomach pain — call your doctor, don't wait it out.
