While not a cure, gabapentin has been shown in studies to significantly reduce the intensity of sciatic nerve pain for some patients. This medication works by calming overactive nerve activity and dulling pain signals to the brain . Gabapentin changes the way the brain and body exchange messages. It calms the nerves by blocking pain-causing neurotransmitters, making gabapentin an effective treatment for sciatica and Chronic sciatica (CS), like most neuropathic pain states, is often resistant to simple treatment regimens. 1,2 Chronic sciatica is sciatica lasting longer than 3 months. 3 Neuropathic pain states are typically managed by super-adding anticonvulsant drugs onto simple drug regimens. The drugs most commonly used are gabapentin (GBP) or pregabalin Gabapentin is widely prescribed for management of peripheral neuropathic pain syndromes. To our knowledge, however, these two case reports are the first to describe sciatica successfully controlled with gabapentin. In this review, no evidence has been found to support the use of pregabalin or gabapentin for sciatica pain or low back pain, since the effect is not superior to placebo. In addition, adverse effects of different considerations associated with their use have been reported. Gabapentin is a remedy for nerve pain that’s also prescribed for back pain. See how it works and if it can help back pain from sciatica, shingles, and more. Nerve pain medication: Gabapentin (Neurontin) and pregabalin (Lyrica) may help reduce neck and back nerve pain, especially sciatica. Begin with low doses to avoid daytime drowsiness and fall risk. Muscle relaxants. Tizanidine (Zanaflex) and baclofen (Lioresal) may reduce pain from muscle spasms. Gabapentin can help relieve sciatica, intense pain that runs along the sciatic nerve from the lower back through the hips and buttocks (12). Sciatica affects one side of the body and is usually caused by disk herniation or spinal stenosis (12). How does gabapentin work to relieve sciatic nerve pain? In general, gabapentin calms down neurons (nerve cells) to relieve nerve pain. It does this by lowering the amounts of excitatory chemicals, like norepinephrine and glutamate, in the nervous system. Despite the specific indications of gabapentinoids, there is a notable increase in the off-label prescription of, which has raised the concern about the misuse of these drugs since the benefits remain unclear. 17, 18, 19 To our knowledge regarding their use on sciatica, pain relief only has been reported in one trial comparing gabapentin with placebo 20 and in no one of those investigating Sciatica pain originates from the compression, irritation, or damage of the sciatic nerve, resulting in aching in the lower back that extends through the leg. This condition is often accompanied by limitations in physical functionality and sensory symptoms like numbness or a prickling feeling. Surgical diskectomy can be offered to patients with refractory sciatica, but there is only modest, short-term improvement in leg pain and disability scores. Gabapentin (Neurontin, 900 to 3,600 Robertson K, Marshman LAG, Plummer D, Downs E. Effect of Gabapentin vs Pregabalin on Pain Intensity in Adults WIth Chronic Sciatica: A Randomized Clinical Trial. JAMA Neurol. 2018 Oct 15. doi: 10.1001/jamaneurol.2018.3077. [Epub ahead of print] PMID: 30326006 Others believe sciatica is a form of ‘neuropathic’ pain caused by compression or irritation of the roots or nerves that comprise the sciatic nerve [1, 4]. Chronic sciatica (CS) is sciatica which has been present for more than 3 months despite active conservative management, including physical therapy. Drugs like gabapentin, duloxetine, nortriptyline and pregabalin can be useful for managing severe pain or pain that makes it hard to sleep. Corticosteroids are another treatment option. These potent anti-inflammatory drugs are delivered via an injection that places the medication just where it is needed. The normal dosage of Gabapentin for sciatica is 300mg once a day. However, Gabapentin dosage for sciatica nerve pain can be increased up to three times a day depending on the severity of the individual’s condition. Sciatica is commonly seen in primary care. Its prevalence in the general population varies between 3% and 14%, depending on the definition used. 1 The prognosis of acute sciatica is generally favourable: data from a prospective study of 183 patients with a median disease duration of 16 days show that in approximately one third of patients, symptoms improve greatly (ie, measured on a 4 point Gabapentin is FDA-approved as Neurontin to treat partial seizures in adults and children with epilepsy. Partial seizures are convulsions that originate from a single location in the brain. Neurontin is also approved to treat a type of nerve pain called postherpetic neuralgia, or PHN. How Gabapentin Helps with Sciatica Pain. Gabapentin’s ability to alleviate sciatica pain lies in its mechanism of action. By modulating the release of certain neurotransmitters involved in pain perception, Gabapentin can reduce the intensity and frequency of pain signals traveling from the sciatic nerve to the brain.
