Neurological (neuropathic) itch is a chronic itch caused by nerve damage. It can involve either the central nervous system or the peripheral nervous system. The other three basic types of itch are as follows: Pruriceptive itch: This is an itch that starts in peripheral nerves in the skin. In the present study, the use of oral gabapentin 300 mg a day for the treatment of itching caused by NP showed to be efficient and led to a significant improvement in rates of itching intensity as assessed by the VAS. Gabapentin should be considered as a treatment option in patients with suspected neuropathic scalp pruritus; the dose of gabapentin is usually started low and titrated up to an effective dose . Adverse effects reported include dizziness, peripheral edema, and worsening of diabetes mellitus. pruritus and neuropathic or neurogenic itch, in patients who fail conservative therapies. (J Am Acad Dermatol 2016;75:619-25.) Key words: gabapentin; itch; neurogenic itch; neuropathic itch; pregabalin; pruritus; uremic pruritus. C hronic pruritus is defined as itch lasting longer than 6 weeks.1 It is associated with both primary dermatologic A neuropathic itch is an itch that results from nervous system damage rather than issues with the skin. There are many causes of neuropathic itch, including stroke, diabetes, and shingles. Gabapentin is approved by the UD Food and Drug Administration for the treatment of seizures and PHN, 52 and is effective in the treatment of neuropathic forms of itch, such as brachioradial pruritus, prurigo nodularis, and notalgia paresthetica. 53 There are promising case reports regarding the use of gabapentin in scalp dysesthesia, 20 Often the first approach to treat neuropathic itch is through medications. Some of the more common oral medications that may be prescribed include: Amitriptyline. This antidepressant also acts There is currently no standardized algorithm for the treatment of chronic pruritus (CP), or itch lasting more than 6 weeks, in adults aged ≥ 65 years. The antiepileptic agents gabapentin and pregabalin, however, are gaining popularity in the dermatologic community for their efficacy in treating CP of neuropathic origin. Yet the lack of literature specifically looking at the safety and Gabapentin, even at low doses, is often used by HMGS Dermatology providers to treat neuropathic pruritus when standard therapy is ineffective. This drug has been used safely for years to treat pain after shingles (postherpetic neuralgia). Neuropathic Itch Symptoms Persistent Itching. Neuropathic itch is characterized by a persistent itch. Most patients with itch, whether it's inflammatory or neuropathic, will require at least 2,400 mg daily.” Another voltage-gated calcium channel blocker, pregabalin, has shown utility in treating uremic, iatrogenic, idiopathic and drug-induced itch, Dr. Elmariah says. Herein, the use of gabapentin and pregabalin, 2 medications well known for treating neuropathic pain and epilepsy that are occasionally used for relieving chronic pruritus is explored. The findings from original sources published to date to evaluate the use of gabapentin and pregabalin as antipruritic agents are explored. Second-line therapies for generalized or severe neuropathic itch include gabapentin, pregabalin, amitriptyline, carbamazepine, or oxcarbazepine. They should be started at lower doses and increased as needed while monitoring for adverse effects. Gabapentin is successfully being used to treat skin conditions associated with pain or pruritus of neuropathic origin. What is gabapentin used for? Gabapentin is proving to be useful in reducing the symptoms of pain and unpleasant sensations caused by the following skin conditions: Pruritus (itch) In patients on haemodialysis Chronic pruritus is a distressing symptom that is often refractory to treatment. Patients frequently fail topical therapies and oral over-the-counter antihistamines, prompting the clinician to consider alternative therapies such as neuroactive agents. Herein, the use of gabapentin and pregabalin, 2 medications well known for treating neuropathic pain and epilepsy that are occasionally used for Gabapentin is a well-established treatment option for itch with a reassuring safety profile that does not require continued lab monitoring. Generalized itching is a common cause of visits to the dermatologist and can be difficult to treat, leading to sleepless nights and inability to function. Itch and pain have shared signaling pathways on an anatomical level. Both pruritic and painful stimuli are detected by the nerve terminals of primary afferent fibers, then transmitted to the thalamus via the spinal cord dorsal horn and the spinothalamic tract. 10 In the past decade, however, researchers discovered itch-specific molecular pathways distinct from pathways of pain transmission Itching isn't a side effect of gabapentin according to Mayo. Itching can be a side effect of opiate use. itch, as well as small fiber neuropathies such as postherpetic neu-ralgia.6 Patients with other itchy conditions such as prurigo nod-ularis, aquagenic pruritus, and uremic pruritus have also reported relief of itch with capsaicin.11,12 Additionally, a more potent 8% capsaicin patch can provide prolonged relief in neuropathic itch One of the earliest reports on the use of gabapentin for neuropathic itch was that of Bueller et al. in 1999, who treated a 54-year-old woman with brachioradial pruritus. At the time of their report she had remained asymptomatic for 4 months on a schedule of gabapentin 300 mg six times daily [ 17 ]. Neuropathic itch is the result of excess peripheral firing or dampened central inhibition of itch pathway neurons and a symptom of the same central and peripheral nervous system disorders that cause neuropathic pain, such as sensory polyneuropathy, radiculopathy, herpes zoster, stroke, or multiple sclerosis, according to Martin Steinhoff, M.D
