Gabapentin is an anti-seizure drug that is sometimes prescribed to help prevent migraines. However, there is conflicting research on whether it's effective for this use. It may also be prescribed for conditions such as diabetic neuropathy, restless leg syndrome, and fibromyalgia. Many of the drugs used for migraine prophylaxis are associated with significant adverse side effects. Given the efficacy of gabapentin in migraine prophylaxis and its good tolerability profile, it should be considered an important addition in the management of patients who are candidates for migraine prophylaxis. However, little evidence is available on the effects and mechanisms of action of gabapentin during the migraine attack period. Gabapentin's analgesic effect may result from the antagonism of N-methyl-D-aspartate receptors and central nervous system calcium channels[5,6]. Migraine is a common, multifactorial neurovascular disorder. Objective: Gabapentin (GBP), originally an antiepileptic drug, is more commonly used in the treatment of pain, including headache disorders. Off-label GBP is used in headache disorders with some success, some failure, and much debate. Off-label, gabapentin has been used in the treatment of migraine and other types of headache, including cluster and tension headaches. It shows potential as an option for those living with migraine and other headache disorders. Gabapentin is an anticonvulsant used off-label to help prevent migraine attacks. Learn about why it’s used and how it works. Studies were required to be prospective, controlled trials of gabapentin/gabapentin enacarbil or pregabalin taken regularly to prevent the occurrence of migraine attacks, to improve migraine‐related quality of life, or both. Two review authors independently selected studies and extracted data. Recurrent migraines can be functionally disabling and can impair quality of life. The disabling nature of migraine headaches leads to frequent visits to outpatient clinics and emergency department facilities, causing significant health and financial burdens. Headaches fall in the top five causes of emergency department visits and the top twenty reasons for outpatient visits.[1] The overall Generic Name Gabapentin DrugBank Accession Number DB00996 Background. Gabapentin is a structural analogue of the inhibitory neurotransmitter gamma-aminobutyric acid that was first approved for use in the United States in 1993. 16 It was originally developed as a novel anti-epileptic for the treatment of certain types of seizures 14,5 - today it is also widely used to treat neuropathic pain. 8 Despite the conflicting evidence surrounding select studies, a significant amount of evidence shows that GBP has benefit for a majority of primary headache syndromes, including chronic daily headaches. GBP has some efficacy in migraine headache, but not sufficient evidence to suggest primary therapy. Since adverse events were common among the gabapentin-treated patients, it is advocated that gabapentin should not be used in routine clinical practice. Gabapentin enacarbil is not efficacious for the prophylaxis of episodic migraine in adults. There is no published evidence from controlled trials of pregabalin for the prophylaxis of episodic Migraines impose significant health and financial burdens. Approximately 38% of patients with episodic migraines would benefit from preventive therapy, but less than 13% take prophylactic medications. Gabapentin is used "off-label" for migraine prevention and treatment, including migraines with or without aura, vestibular migraines. It reduces the frequency of headaches, pain intensity, and the use of symptomatic medications 1 , 2 . sign in; Don't have an account ?

In addition, gabapentin appears generally well tolerated with mild to moderate somnolence and dizziness. Gabapentin Uses. Gabapentin is a versatile medication with a range of therapeutic applications. Its primary uses include treating seizures, managing neuropathic pain, and addressing anxiety and insomnia. In addition, ongoing research is exploring its potential in managing other conditions, such as restless leg syndrome and migraine headaches. The recommendations on what information and self-care advice should be given to people with migraine are based on clinical guidelines National headache management system for adults [], Headaches in over 12s: diagnosis and management [], Primary care management of headache in adults [Becker, 2015] and Pharmacological management of migraine [], the American Headache Society updated consensus Does gabapentin (Neurontin) help prevent episodic migraine? Evidence-Based Answer Gabapentin does not decrease the frequency of migraine headaches and is not recommended for prophylactic therapy. Gabapentin shows to have an effective therapeutic action in the prophylactic treatment of migraine. Our observations indicate that gabapentin is well tolerated by patients and that reduces headache frequency and use of symptomatic drugs in both groups.
