Standard painkillers like ibuprofen and acetaminophen do little for nerve pain. The medicines that actually work are ones you might not expect: certain antidepressants and anti-seizure drugs, both of which calm overactive nerve signals through different pathways. These are the cornerstone treatments recommended by major neurology guidelines, and finding the right one often takes some trial and patience.
Why Regular Painkillers Don’t Work
Nerve pain (neuropathic pain) comes from damaged or misfiring nerves, not from inflammation or tissue injury. That’s why anti-inflammatory drugs like ibuprofen and naproxen, which work well for a sore knee or headache, rarely help. The belief that NSAIDs lack efficacy for nerve pain is so widely accepted that most treatment guidelines either don’t mention them at all or note that evidence of benefit is limited or lacking. It’s possible they help people with very mild nerve pain, but for moderate to severe cases, they’re generally not effective.
This mismatch catches a lot of people off guard. You reach for the same over-the-counter options that handle every other kind of pain, get no relief, and wonder what’s going on. The answer is that nerve pain requires medications designed to change how nerves transmit signals, not ones that reduce swelling.
Anti-Seizure Medications
Gabapentin and pregabalin are among the most commonly prescribed medicines for nerve pain. They were originally developed for epilepsy, but they turned out to be effective pain relievers too. Both work by binding to a specific part of calcium channels on nerve cells, which reduces the release of pain-signaling chemicals. By quieting these overexcited nerves, they dial down the burning, shooting, or tingling sensations that characterize neuropathic pain.
In studies of diabetic neuropathy, gabapentin has a “number needed to treat” of 3.7, meaning roughly one in every four people who try it gets meaningful relief. For postherpetic neuralgia (nerve pain after shingles), the number is similar at 3.2. These aren’t miracle numbers, but they represent real, measurable benefit for a condition that’s notoriously hard to treat.
The most common side effects are drowsiness, dizziness, and nausea. Alcohol makes these worse and should be avoided. Doses typically start low and increase gradually over weeks until pain improves or side effects become a problem.
Antidepressants That Treat Pain
Two classes of antidepressants are first-line treatments for nerve pain: tricyclic antidepressants (like amitriptyline and nortriptyline) and SNRIs (like duloxetine and venlafaxine). Their pain-relieving effect is separate from their antidepressant effect. They work at lower doses than those used for depression, and relief can begin within a week rather than the several weeks it takes for mood benefits to kick in.
Tricyclic Antidepressants
Tricyclics are the oldest option and, by the numbers, the most effective. In diabetic neuropathy, they have a number needed to treat as low as 1.4 at optimal doses, and around 2.3 to 2.5 for postherpetic neuralgia, peripheral nerve injury, and central pain conditions. That means roughly one in two or three patients gets significant relief.
Treatment usually starts at 10 to 25 mg taken at bedtime, then increases in small steps every few days. The average effective dose for amitriptyline is about 75 mg per day, well below the 150 mg typically used for depression. The tradeoff is side effects: dry mouth, constipation, blurred vision, dizziness, upset stomach, and sexual dysfunction. These effects are why tricyclics aren’t always the first choice despite their strong efficacy, particularly for older adults who may be more sensitive to them.
SNRIs
Duloxetine is the most widely studied SNRI for nerve pain, with proven efficacy at 60 to 120 mg per day for painful diabetic neuropathy. It typically starts at 30 mg daily and moves up to 60 mg. SNRIs tend to cause fewer side effects than tricyclics. The main ones are nausea, dizziness, and sweating. For many people, SNRIs offer a better balance of pain relief and tolerability.
Topical Treatments
When nerve pain is localized to a specific area, topical options can help without the whole-body side effects of oral medications. Three topical treatments have FDA approval for neuropathic pain conditions: a high-concentration capsaicin patch (8%), a lidocaine patch (5%), and a lidocaine topical system (1.8%).
Capsaicin is the compound that makes chili peppers hot. At prescription strength, it overwhelms and then desensitizes the local pain-sensing nerve fibers. The lidocaine patches numb the area directly. Both are applied to the skin over the painful region and work best for conditions like postherpetic neuralgia where the pain is confined to a defined patch of skin. They’re sometimes used alongside oral medications for added relief.
Carbamazepine for Trigeminal Neuralgia
One type of nerve pain has its own dedicated treatment. Trigeminal neuralgia causes sudden, severe jolts of facial pain, and carbamazepine is the go-to medication. It’s another anti-seizure drug, but it works through a different mechanism than gabapentin or pregabalin. Treatment typically starts at 200 mg per day, with the dose adjusted upward as needed, usually not exceeding 1,200 mg daily. If you have sharp, electric-shock-like pain in your face, this distinction matters because carbamazepine is far more effective for this specific condition than the other options.
What Opioids Won’t Do
The American Academy of Neurology’s guidelines, reaffirmed in February 2025, state clearly that clinicians should not use opioids for painful diabetic neuropathy. Beyond the well-known risks of dependence, opioids simply aren’t a good fit for chronic nerve pain. The guidelines emphasize exploring oral, topical, and non-drug treatments instead.
Finding the Right Medication Takes Time
One of the most frustrating realities of nerve pain treatment is how long it can take. Finding a medication that works can require many months or even longer. Most drugs need to be started at a low dose and slowly increased, and if the first one doesn’t help, switching to a different medication class is the recommended approach rather than trying another drug in the same class. For example, if gabapentin isn’t helping, moving to an antidepressant is more likely to succeed than switching to pregabalin.
This class-switching strategy is a key recommendation from the AAN. Each medication class targets nerve pain through a different mechanism, so a poor response to one class doesn’t predict how you’ll respond to another. Many people end up trying two or three different medications before landing on the right fit. Keeping a simple pain diary noting your daily pain levels and any side effects can help you and your prescriber make faster, better decisions about what to try next.
