Background: One of the most common peripheral nerve complications of diabetes is painful diabetic peripheral neuropathy (DPN). Although tricyclic antidepressants (TCAs) have traditionally been used to relieve the pain of this condition, gabapentin's reported efficacy in various neuropathic pain states and its favorable side-effect profile Gabapentin has been shown to be beneficial in treating several types of neuropathic pain; however, the mechanism of action by which gabapentin exerts its analgesic effect is still unknown.¹ It is suggested that gabapentin may block the calcium channel alpha (2)delta (a2d)-1 receptor in the brain. Nerve pain as a result of diabetic neuropathy, which happens when nerves in the feet damaged by diabetes cause chronic burning pain. How does gabapentin work in nerve pain? The exact way that gabapentin works to relieve pain is not known. It may change the way the body senses and reacts to pain. The authors conclude that gabapentin provides safe, effective pain relief in patients with diabetic neuropathy. The effects of gabapentin are similar to those found with Gabapentin has undergone extensive research and has been used for many years to treat people for a variety of pain disorders including diabetic nerve pain (neuropathy) and other nerve pain disorders like shingles pain (post-herpetic neuralgia), and fibromyalgia. Gabapentin at a dose of 1800 to 3600 mg daily (1200 to 3600 mg gabapentin encarbil) can provide good levels of pain relief to some people with postherpetic neuralgia and peripheral diabetic neuropathy. Gabapentin is a prescription antiepileptic medication commonly used to treat postherpetic neuralgia, a type of nerve pain, and other neuropathic pain conditions.

Anecdotal reports suggest that gabapentin ameliorates pain associated with neuropathy and other neurological conditions with few side effects.2 3 We conducted a randomised, double blind, placebo controlled trial to study the effect of low dose gabapentin in patients with painful diabetic neuropathy. Gabapentin (Gralise, Neurontin) also is an option. Side effects may include drowsiness, dizziness, and swelling in the hands and feet. Antidepressants. Some antidepressants ease nerve pain, even if you aren't depressed. Tricyclic antidepressants may help with mild to moderate nerve pain. But it’s not approved for diabetic neuropathy, and it’s not as well studied as duloxetine for this purpose. But some people still use it for diabetic neuropathy. Amitriptyline. Amitriptyline is an older and cheaper medication that can treat diabetic neuropathy. Like gabapentin and venlafaxine, it’s not FDA-approved for this purpose. Gabapentin has an average rating of 6.0 out of 10 from a total of 54 reviews for the off-label treatment of Diabetic Peripheral Neuropathy. 54% of reviewers reported a positive experience, while 35% reported a negative experience. %PDF-1.5 %âãÏÓ 1095 0 obj > endobj xref 1095 78 0000000016 00000 n 0000002874 00000 n 0000003245 00000 n 0000003281 00000 n 0000003367 00000 n 0000003447 00000 n 0000003521 00000 n 0000003598 Among DPN symptoms, neuropathic pain, often severe, affects up to 30% of all individuals with DPN and is challenging to manage, resulting in increased risks of associated problems such as sleep disturbances, further reduced quality of life, polypharmacy, socioeconomic consequences (e.g., higher health care costs and reduced ability to work or perform daily activities), morbidity, and mortality Using these more stringent criteria, the Cochrane review concluded that gabapentin was effective in treating diabetic peripheral neuropathic pain at appropriate doses and treatment duration 3. Medication Doesn't Address Underlying Causes of Nerve Pain. One of the most significant drawbacks of relying solely on gabapentin for neuropathy is that it doesn't tackle the root cause of your nerve pain. It's a symptomatic treatment—meaning it may mask the pain without addressing why you're experiencing neuropathy in the first place. Sometimes other terms are used, including cryptogenic neuropathy or chronic polyneuropathy of undetermined cause. For some people, neuropathy is due to diabetes, alcohol abuse, medications, or other conditions. But in nearly half of all cases, sensory polyneuropathy is idiopathic. No cause, no cure This summary uses a Cochrane review, updated in 2014, to address the efficacy of gabapentin compared with placebo to palliate neuropathic pain. 3 The Cochrane review includes 37 trials enrolling Doctors often prescribe gabapentin off-label to treat conditions such as: pain from diabetic neuropathy, which is numbness or uncomfortable tingling caused by nerve damage from diabetes; nerve pain in the neck and back from conditions such as sciatica, a painful compression of the sciatic nerve Pregabalin (Lyrica), gabapentin (Neurontin), amitriptyline (except in older adults), or duloxetine (Cymbalta) should be used as first-line treatment for painful diabetic peripheral Gabapentin dosage for sciatica nerve pain. Gabapentin dosages for sciatica nerve pain typically start at 300 mg to 900 mg by mouth 3 times a day. This dosage is slowly increased by your prescriber depending on your response to the medication. Common side effects of gabapentin. Common side effects of gabapentin may include: Dizziness
