12.1 Mechanism of Action Naproxen has analgesic, anti-inflammatory, and antipyretic properties. Naproxen sodium has been developed as a more rapidly absorbed formulation of naproxen for use as an analgesic. The mechanism of action of naproxen, like that of other NSAIDs, is not completely understood but involves inhibition of cyclooxygenase (COX-1 and COX-2). Naproxen is a potent inhibitor of prostaglandin synthesis in vitro. Naproxen concentrations reached during therapy have produced in vivo effects. Prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in inducing pain in animal models. Prostaglandins are mediators of inflammation. Because naproxen is an inhibitor of prostaglandin synthesis, its mode of action may be due to a decrease of prostaglandins in peripheral tissues.

I'm hypermobile and fat and this has caused me to develop osteoarthritis in my hip, normal NSAIDs don't work on me and I'm allergic to naproxen. I'm scared of becoming addicted to opioids because they seem to be the only thing that helps but I've already gotten 2 prescriptions of them and I'm curren
This is more of a rant I guess. I've been struggling with pain for over a decade now, and no matter how bad it gets, I'm given naproxen or acetaminophen. Naproxen doesn't work for me, and it requires high doses of acetaminophen for me to get a small amount of relief. But they are still the only pai
Had a flare up today and usually when this happens I can’t walk. I usually end up in the ER because when I call my doctor I always get “we can’t help you unless you come in” Ma’am you diagnosed me and all I need is a steroid pack and some naproxen to reduce swelling. So when I was finally mobile eno

I asked for 500mg naproxen and was given a muscle relaxer to take 3 times a day i’m up to at least 12 pills a
Hey everyone! I’ve been seeing a lot of posts lately in this sub and in others about people asking for little things that help manage the pain, so I thought I’d compile a list of stuff that helps me and others can tack on what helps them in the comments. I hope someone finds this useful! - **Prescri
