Several types of medications, supplements, and topical treatments can reduce neuropathy symptoms, though no single option works for everyone. The most effective approaches target how your nerves send pain signals, and the right choice depends on the type of neuropathy you have, its underlying cause, and how your body responds. Most people need to try more than one option before finding meaningful relief.
Prescription Medications That Work Best
Clinical guidelines recommend two main classes of medication as first-line treatment for neuropathic pain: anticonvulsants and certain antidepressants. These aren’t prescribed because neuropathy is related to seizures or depression. Both drug classes change how your spinal cord and brain process pain signals from damaged nerves.
Among anticonvulsants, gabapentin and pregabalin are the most commonly prescribed. Pregabalin is specifically approved for diabetic peripheral neuropathy and pain following shingles. Gabapentin is widely used off-label for the same conditions. Both work by calming overactive nerve signals. The most common side effects are dizziness and drowsiness, which tend to be mild and fade over time. Regulatory reviews have found that higher doses don’t necessarily help more: gabapentin shows no additional benefit above 1,800 mg per day, and pregabalin above 300 mg per day increases side effects without meaningfully improving pain relief.
On the antidepressant side, duloxetine is approved for diabetic neuropathy and works by boosting levels of two chemical messengers (norepinephrine and serotonin) in the spinal cord. This strengthens your body’s built-in pain suppression system. Doses above 60 mg per day don’t add benefit but do raise the risk of side effects. Older antidepressants like amitriptyline and nortriptyline are also used off-label. These have a broader mechanism: beyond boosting pain-suppressing chemicals, they block sodium channels on damaged nerves (reducing the misfiring that causes burning and shooting pain) and interact with several other pain-related pathways. The trade-off is more side effects, including dry mouth, constipation, and weight gain.
If one medication in a class isn’t working or causes side effects you can’t tolerate, guidelines from the American Academy of Neurology recommend switching to a different class rather than trying another drug in the same class. Opioids are specifically not recommended for diabetic neuropathy.
How Long Before You Feel Relief
Neuropathy medications aren’t like painkillers that work within an hour. Most need to be started at a low dose and gradually increased over several weeks, both to minimize side effects and to find your effective dose. You should expect a minimum of four to six weeks at an adequate dose before judging whether a medication is working. Some supplements, like B12, can take four months or longer to show improvement. This slow timeline is one of the most frustrating parts of neuropathy treatment, and it’s worth knowing upfront so you don’t abandon something that might have worked with more time.
Topical Options for Localized Pain
When neuropathy pain is concentrated in a specific area, like the feet, topical treatments can help without the systemic side effects of oral medications. Two main options are available.
Lidocaine patches (5% concentration) numb the skin and underlying nerves in the area where they’re applied. They’re available by prescription and provide localized relief while the patch is on. Capsaicin, the compound that makes chili peppers hot, is available in both over-the-counter creams (low concentration) and prescription patches (8% concentration). The prescription patch is applied in a clinical setting for about 60 minutes and works by overwhelming and then desensitizing the pain-sensing nerve fibers in the skin. The initial application burns intensely, but the resulting pain relief can last weeks. Over-the-counter capsaicin creams require consistent daily application for several weeks before they start helping.
Supplements Worth Considering
Vitamin B12
B12 deficiency is one of the treatable causes of neuropathy, and correcting it can reverse nerve damage if caught early enough. Even people with normal B12 levels may benefit: one study found that 500 mg of B12 taken three times daily improved neuropathy symptoms after four months in people with diabetic neuropathy and normal B12 levels. If you have a confirmed deficiency with neurological symptoms, treatment is more aggressive. Injections every other day for up to three weeks are recommended for severe cases. For milder deficiency, high-dose oral B12 (1 to 2 mg daily) has been shown to be as effective as injections for correcting both blood levels and neurological symptoms.
Alpha-Lipoic Acid
Alpha-lipoic acid (ALA) is one of the more studied supplements for diabetic neuropathy. It’s an antioxidant that appears to improve nerve blood flow and reduce oxidative damage. Clinical trials have used 600 mg taken three times daily (1,800 mg total) for an initial four-week loading period, then 600 mg once daily for maintenance. Results are mixed but generally positive for reducing the core symptoms of diabetic neuropathy: stabbing pain, burning, tingling, and numbness. ALA is available over the counter and is generally well tolerated.
Acetyl-L-Carnitine
Acetyl-L-carnitine (ALCAR) has been studied for diabetic, chemotherapy-induced, and HIV-related neuropathy. The evidence is modest. A review of three placebo-controlled trials using 1.5 to 3 grams daily for a year found some pain reduction in diabetic neuropathy, though the evidence quality was rated low. Results for chemotherapy-induced neuropathy are conflicting. The Linus Pauling Institute suggests a daily dose of 500 mg to 1 gram if you choose to try it. It’s not a first-line treatment, but it’s an option for people looking to add something alongside other therapies.
TENS Units for At-Home Pain Relief
Transcutaneous electrical nerve stimulation (TENS) uses a small, battery-powered device that sends mild electrical pulses through pads placed on your skin. The pulses interrupt pain signals traveling to your brain. TENS units are available without a prescription and are generally safe to use as often as you’d like, with most people using them for up to 60 minutes per session, several times a day.
Pain relief typically begins immediately during the session. For most people, the relief lasts up to an hour after turning the device off. Some report up to 24 hours of benefit, while others notice pain returning as soon as the session ends. TENS won’t treat the underlying nerve damage, but it can be a useful tool for managing flare-ups without medication.
Treating the Underlying Cause
Everything above manages symptoms, but the most important step is addressing what’s damaging your nerves in the first place. Diabetes is the most common culprit, and tightly controlling blood sugar is the single most effective way to slow or prevent further nerve damage. Other reversible causes include B12 deficiency, alcohol use, thyroid problems, and certain medications (particularly some chemotherapy drugs). If your neuropathy is caused by one of these, treating the root cause can halt progression and, in some cases, allow nerves to partially recover. Peripheral nerves do have some capacity to regenerate, but recovery is slow and incomplete once damage is advanced.
