The established therapeutic dosing for gabapentin in neuropathic pain trials is 1800-3600 mg/day in 3 divided doses in patients with normal renal function. 3 This means the minimum effective dose is 600 mg 3 times a day. Renal adjustments are recommended in patients with CrCl below 60 mL/min. The usual dose to treat nerve pain in adults is 900mg to 3,600mg a day, split into 3 doses.

Below is a general guideline for dosing: Gabapentin is primarily used for: Neuropathic Pain: Effective in alleviating pain from nerve damage. Postherpetic Neuralgia: Reduces pain following shingles. Seizure Disorders: Acts as an adjunctive therapy for partial seizures. Gabapentin is also used as an adjunct to more potent anticonvulsants and for the management of certain types of neural pain. Definition and uses of gabapentin. Gabapentin is an anticonvulsant medication primarily used to treat seizures and nerve pain. Detailed Gabapentin dosage information for adults and children. Includes dosages for Restless Legs Syndrome, Epilepsy and Postherpetic Neuralgia; plus renal, liver and dialysis adjustments. Gabapentin works best for patients with diabetic neuropathy or sciatica, which causes nerve pain, numbness, and tingling in the legs. It can reduce pain signals to the nerves. Gabapentin can be purchased in various forms, including pills, oral solutions, capsules, and extended-release tablets.

Gabapentin for Neuropathic Pain Initial dose: 300 mg once daily, with gradual increases as needed. Maintenance dose: 900-3600 mg per day, divided into three doses. The dosage of gabapentin required for nerve pain may vary depending on the individual's pain level, age, weight, and other health conditions. Typically, the starting dose is 300 mg per day, which can be gradually increased to 3600 mg per day in divided doses. Gabapentin for other types of nerve pain. Gabapentin can also treat nerve pain from PHN, which is the most common complication of shingles. It’s also used off-label to treat diabetes-related nerve pain. If you have nerve pain from other causes — like back injury, nerve injury, or after surgery — it still may help. The typical starting dosage of gabapentin for seizures is 300 mg by mouth three times a day, with or without food.

The maximum gabapentin dosage is 3,600 mg per day, but higher doses are more likely to cause side effects.Restless legs syndrome Gabapentin is commonly used to treat and prevent seizures in people with epilepsy or to treat nerve pain (postherpetic neuralgia) that can occur after a viral infection called shingles. Neurontin is used in adults to treat neuropathic pain (nerve pain) caused by herpes virus or shingles (herpes zoster). Neurontin is also used to treat seizures in adults and children who are at least 3 years old. Use only the brand and form of gabapentin your doctor has prescribed. For immediate-release gabapentin (Neurontin), dosing may be initiated with 300 mg on day 1, doubled on day 2 (300 mg twice a day), and tripled on day 3 (300 mg 3 times a day). The dose can then be titrated up as needed for pain relief to a maximum dose of 1,800 mg daily (divided into 3 daily doses). Gabapentin is licensed for the treatment of peripheral neuropathic pain such as painful diabetic neuropathy and postherpetic neuralgia in adults [ABPI, 2020a].However, the National Institute for Health and Care Excellence (NICE) recommends gabapentin as a first-line treatment option for adults with all neuropathic pain (except trigeminal neuralgia) [NICE, 2019a]. Gabapentin is an anticonvulsant used to treat nerve related back pain, such as sciatica. The typical starting dose of gabapentin for sciatic nerve pain for most patients is 300mg once a day
