US marketing approval for gabapentin was granted in 2002 for postherpetic neuralgia; in Europe, the label was changed to include peripheral neuropathic pain in 2006. Gabapentin has the trade name Neurontin, and is also available as generic products in some parts of the world. Gabapentin has a half‐life of five to seven hours. The purpose of this report is to review the clinical evidence on the efficacy, safety and guidelines for use of gabapentin in adults with neuropathic pain, and to examine evidence on the misuse or abuse of gabapentin and other drugs for neuropathic pain. Gabapentin at doses of 1800 mg to 3600 mg daily (1200 mg to 3600 mg gabapentin encarbil) can provide good levels of pain relief to some people with postherpetic neuralgia and peripheral diabetic neuropathy. Evidence for other types of neuropathic pain is very limited. Gabapentin at doses of 1800 mg to 3600 mg daily (1200 mg to 3600 mg gabapentin encarbil) can provide good levels of pain relief to some people with postherpetic neuralgia and peripheral diabetic neuropathy.

Evidence for other types of neuropathic pain is very limited. The outcome of at least 50% pai 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 (A Comprehensive Look at Peripheral Neuropathy and Nerve Pain Treatment) If you’re someone dealing with nerve pain or peripheral neuropathy, you may have been prescribed gabapentin as part of your treatment plan. Gabapentin is commonly used to manage nerve pain by calming down the overactive nerves that send pain signals to your brain. Medicines such as gabapentin (Gralise, Neurontin, Horizant) and pregabalin (Lyrica), developed to treat epilepsy, often improve nerve pain. Side effects can include drowsiness and dizziness. Topical treatments. Lidocaine cream that is available without a prescription can be applied to the skin. Research supports the use of the anticonvulsants gabapentin (Gralise, Neurontin, Horizant) and pregabalin (Lyrica) to help relieve pain caused by damaged nerves. Both gabapentin and pregabalin are particularly effective in the treatment of postherpetic neuralgia, diabetic neuropathy and pain caused by a spinal cord injury. Current medication management for neuropathic pain includes select neuromodulating agents such as anticonvulsants, serotonin norepinephrine reuptake inhibitors, tricyclic antidepressants, and certain opioids. 1,2 Gabapentin remains among the most commonly used anticonvulsants for neuropathic pain. Gabapentin shows substantial benefit (at least 50% pain relief or a patient global impression of change (PGIC) "very much improved") for neuropathic pain (postherpetic neuralgia or peripheral diabetic neuropathy) in 30–40% of subjects treated as compared to those treated with placebo. The same review compared gabapentin to an inactive medicine (placebo) in almost 6,000 adults with chronic pain from PHN or diabetic neuropathy. Study participants were given either gabapentin or a placebo for 4 to at least 12 weeks. Gabapentin is a prescription antiepileptic medication commonly used to treat postherpetic neuralgia, a type of nerve pain, and other neuropathic pain conditions.

Pregabalin (Lyrica), gabapentin (Neurontin), amitriptyline (except in older adults), or duloxetine (Cymbalta) should be used as first-line treatment for painful diabetic peripheral neuropathy. A 1 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 tricyclic antidepressants “Gabapentin at doses of 1800 mg to 3600 mg daily (1200 mg to 3600 mg gabapentin encarbil) can provide good levels of pain relief to some people with postherpetic neuralgia and peripheral diabetic neuropathy.
