Naproxen sodium dosage recommendations depend on the intended use, with typical adult doses for pain and inflammation ranging from 220 mg to 500 mg every 8 to 12 hours [1]. For osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis, a common starting dose is 500 mg to 1,000 mg daily, divided into two doses. Doses can be adjusted based on patient response and tolerance, though exceeding 1,500 mg per day is generally not advised without physician consultation [1].
How does naproxen sodium work for pain?
Naproxen sodium is a nonsteroidal anti-inflammatory drug (NSAID) that works by reducing hormones in the body that cause inflammation and pain. It inhibits cyclooxygenase (COX) enzymes, which are responsible for producing prostaglandins, substances that play a key role in pain and inflammation [2].
What are the different strengths of naproxen sodium available?
Naproxen sodium is commonly available over-the-counter in 220 mg tablets. Prescription strengths can include 250 mg, 275 mg, 375 mg, and 500 mg tablets and capsules [1].
How long does naproxen sodium take to work?

What are the risks of taking naproxen sodium?
Like other NSAIDs, naproxen sodium carries risks, including stomach bleeding, ulcers, and perforation. These serious side effects can occur at any time during treatment, with or without warning symptoms. The risk increases with higher doses and longer durations of use. Cardiovascular risks, such as heart attack and stroke, are also associated with NSAID use. Naproxen sodium can also lead to kidney problems and should be used with caution by individuals with pre-existing kidney conditions [1][2].
How does naproxen sodium compare to other pain relievers?
Naproxen sodium is an NSAID, similar to ibuprofen. It is generally considered to have a longer duration of action than ibuprofen, meaning it may be taken less frequently. Acetaminophen (Tylenol) is another common pain reliever, but it works differently and does not have the same anti-inflammatory effects as naproxen sodium. For severe pain, other classes of pain relievers might be prescribed by a doctor [4].
When does naproxen sodium patent expire?
