Naproxen is a NSAID (nonsteroidal anti-inflammatory drug) that works by reducing hormones that cause inflammation and pain in the body. Naproxen is used to treat pain and inflammation caused by arthritis, ankylosing spondylitis, tendinitis, bursitis, gout, or menstrual cramps. The tablets are available in extended release form, which are used for treating chronic conditions like arthritis and ankylosing spondylitis. Such extended release tablet is not able to treat acute pain.

- Anaprox DS

What are the therapeutic uses of naproxen?
Naproxen is a non-narcotic pain medication frequently prescribed for the treatment of headaches and other minor aches and pains. Naproxen is also helpful when used as an anti-inflammatory agent for conditions such as arthritis, ankylosing spondylitis, bursitis, tendinitis, gout, menstrual cramps and other disorders of the muscles and bones.
How does naproxen work?
The way that naproxen works in the body is fundamentally different to other opioid prescription pain killers that contain oxycodone, tramadol, or hydrocodone. Naproxen is a pain medication that is known to bind to the opioid receptors in the central nervous system and cause sense of well being called euphoria or dissociation. This is the reason that you can also feel high. But it needs very high doses of naproxen to produce such effects, and very high doses of naproxen can cause stomach ulcerations and severe stomachache.
The main mechanism of action of naproxen is completely different from this, as per this, naproxen is a NSAID i.e. nonsteroidal anti-inflammatory drugs which acts by inhibiting the synthesis of prostaglandins. There are cyclooxygenase (COX) enzymes in our body which produces prostaglandins, as soon as naproxen enters into the blood stream, the COX enzymes are blocked, and the pain reduces from minutes to hours. As per mechanism of NSAIDs, these medications are known to alleviate pain, not cause any euphoric effects.
What is the dosage for naproxen?
The usual adult dose for pain is 250 every 6 to 8 hours or 500 mg twice daily using regular naproxen tablets. The usual dose for Naprelan controlled release tablets is 750 to 1000 mg given once daily. For EC-Naprosyn, the usual dose is 375-500 mg twice daily.
Naproxen should be given with food to reduce upset stomach. The dose for rheumatoid arthritis, osteoarthritis, or ankylosing spondylitis is 500 to 1000 mg every 12 hours. Dysmenorrhea is treated with 250 mg every 6 to 8 hours after an initial dose of 500 mg.
How long naproxen stays in your body?
Naproxen is metabolized to 6-0-desmethyl naproxen in the liver and neither naproxen does induce any metabolizing enzymes nor its metabolites. The half life of naproxen and its conjugates is shorter than 12 hours therefore it stays for almost 1 to 2 days in our body. 2-3% of naproxen is eliminated from body in the feces. The metabolites of naproxen may accumulate in the patients with kidney failure.
Naproxen CNS effects
However, there are other ways that naproxen affects the central nervous system. Naproxen may cause neurological effects which can alter or impair physical or mental abilities and affect performance. These include:
- blurred vision
- slowed mental alertness
Naproxen can also cause side effects which affect the gastrointestinal and cardiovascular systems of the body. Furthermore, alcohol consumption increases the risk of gastrointestinal bleeding when combined with naproxen.
Can I get high on naproxen?
No, it is quite less likely that you get high on naproxen. Although there are some online reports of people who get high on naproxen.
Naproxen is a medication that is available over the counter as a non-narcotic anti-inflammatory drug. Naproxen causes lightheadedness actually, visual disturbances, and drowsiness in some users. It is not associated with any kind of euphoric feeling nor does it have abusive properties. Abusers can get high risk of kidney failure and bleeding ulceration in the stomach, if they take higher doses of naproxen in order to achieve a “high” level.
Naproxen “High” experience
There is one example of naproxen high (published on erowid.org), however even in that case, patient took naproxen in combination with cyclobenzaprine.
“I have a herniated disk with 2 pinched nerves/possibly three. I was given by my doctor Naproxen (l 500 mg TEVA-Naproxen EC twice daily) and also Cyclobenzaprine (1 three times daily as needed) as a muscle relaxant. I took it for a very short time as it made me feel like crap. I could only take the two together at bedtime as I could not function on both of them.
I took both to avoid pain while in a test situation and even though it was open-book, I was completely lost. Impossible to concentrate and focus on work. One must take with food but I won’t take both together unless I am going to sleep. I only want to sleep when I do both together and it ruined my day when I needed to do something other than sleep…”
Can I get addicted to naproxen?
No, even after taking naproxen for the long term there are less chances that one can develop addiction to this medication. Even people do not see any kind of withdrawal symptoms after stopping the medication. Also you even cannot get high on naproxen, and cannot develop a mental dependence. However, you should always talk to your doctor before taking this medication regarding interactions associated with it, and you should always seek emergency medical help if you notice rashes on your skin, swelling, and difficulty in breathing or urinating.

Patients who are using naproxen on long-term basis may have serum aminotransferase levels elevated, particularly with high doses. Clinically apparent naproxen induced liver injury is very rare (~1-3 per 100,000 users), but convincing cases have been reported that resemble acute hepatitis and arise within 1 to 6 weeks of starting naproxen. The time to onset can be as long as 12 weeks, but convincing instances of liver injury arising after long term use have not been described. The pattern of serum enzyme elevations has ranged from hepatocellular to cholestatic injury. Immunoallergic features and autoantibodies are not common. In most instances, recovery is rapid once naproxen is stopped. Rare instances of acute liver failure attributed to naproxen have been published, but the role of naproxen in these cases was not very convincingly shown.
