Naproxen is not an effective treatment for nerve pain. While it works well for inflammation-driven pain like arthritis or muscle strains, clinical evidence consistently shows that naproxen and other anti-inflammatory painkillers provide little to no meaningful relief for neuropathic pain, which is pain caused by damaged or dysfunctional nerves.
What the Research Shows
A Cochrane review examining oral anti-inflammatory drugs for neuropathic pain found no indication of any significant pain reduction. The review looked at conditions including chronic low back pain with a nerve component and postherpetic neuralgia (nerve pain following shingles), and concluded there is no evidence to support or refute using these drugs for neuropathic pain conditions. In one of the included studies, patients’ average pain scores barely moved: from 47 out of 100 before treatment to 46 out of 100 after four weeks.
There is one exception worth noting. A 2024 randomized trial tested naproxen specifically for sciatica, where a compressed nerve root causes radiating leg pain. Among 123 adults taking naproxen 500 mg twice daily for 10 days, there was a statistically significant reduction in leg pain compared to placebo. But the actual difference was only about half a point on a 0-to-10 pain scale. The researchers themselves described the benefit as “small, likely clinically unimportant.” There were no differences in how bothersome the sciatica felt or in the need for additional pain medication.
Why Anti-Inflammatory Drugs Miss the Mark
Naproxen works by blocking the production of prostaglandins, chemicals your body releases during inflammation. That makes it effective when inflammation is the primary source of pain, like a swollen joint or a pulled muscle. Nerve pain operates differently. When nerves themselves are damaged, whether from diabetes, shingles, surgery, or compression, the pain signals come from misfiring nerve fibers rather than from inflammatory chemicals at the injury site. Naproxen simply doesn’t target the mechanisms that drive neuropathic pain.
This is why the distinction between nerve pain and inflammatory pain matters so much for choosing the right treatment. If you have sciatica, for instance, part of your pain may come from inflammation around the compressed nerve root, which could explain naproxen’s small effect in that specific condition. But the nerve-related component of the pain, the burning, shooting, or electric sensations, tends not to respond.
Naproxen vs. Nerve Pain Medications
The gap between naproxen and medications designed for nerve pain is significant. In a controlled trial comparing the two for persistent pain after spinal surgery, gabapentin reduced leg pain by 39.2% at its full dose. Naproxen reduced the same type of pain by just 7.7%, and even that small improvement disappeared after six weeks as the pain returned to previous levels. For back pain, gabapentin produced a 20.5% reduction while naproxen showed no significant improvement at all.
The Cochrane review also found that pregabalin, another nerve pain medication in the same class as gabapentin, significantly reduced pain scores in patients where an anti-inflammatory drug alone had no effect. These medications work by calming overactive nerve signaling rather than targeting inflammation, which is why they succeed where naproxen fails.
When Naproxen Might Still Play a Role
Not all pain that feels like nerve pain is purely neuropathic. Many conditions involve a mix of inflammatory and nerve-related pain. A herniated disc, for example, creates both inflammation around the nerve and direct nerve compression. In these mixed-pain situations, naproxen may take the edge off the inflammatory component even if it does nothing for the nerve component itself.
Naproxen starts working within about an hour, reaches its peak effect in 2 to 4 hours, and lasts 8 to 12 hours per dose. If you take naproxen for what you suspect is nerve pain and notice no improvement after a few days, that’s a strong signal that the pain is primarily neuropathic and requires a different approach.
Risks of Long-Term Use Without Benefit
Taking naproxen long-term for pain it isn’t effectively treating exposes you to real risks with no upside. Chronic use increases the risk of peptic ulcers three- to fivefold in older adults, and the rate of hospitalizations for ulcer disease rises sharply after age 65. All anti-inflammatory drugs carry a warning for cardiovascular events including heart attack and stroke. One study found that naproxen users had more than twice the risk of stroke compared to non-users.
Naproxen does carry a slightly lower cardiovascular risk than some other anti-inflammatory drugs, which is sometimes cited as a reason to prefer it for chronic pain conditions. But if it isn’t addressing your nerve pain in the first place, even a relatively lower risk profile doesn’t justify continued use.
What Works Better for Nerve Pain
The medications with the strongest evidence for neuropathic pain work on the nervous system directly. Gabapentin and pregabalin reduce pain by dampening overexcited nerve signals. Certain antidepressants, particularly those that affect both serotonin and norepinephrine, also modify pain processing in ways that help with neuropathic conditions. Topical options like lidocaine patches or capsaicin cream can provide localized relief for some types of nerve pain without systemic side effects.
The right treatment depends heavily on what’s causing your nerve pain. Diabetic neuropathy, postherpetic neuralgia, sciatica, and nerve damage from surgery each have somewhat different treatment profiles. If naproxen isn’t helping your pain, or if your pain has burning, tingling, shooting, or electric-shock qualities, those are signs that a nerve-specific treatment is likely to be more effective.
