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. Children ≥12 years and Adolescents: Initial: 300 mg 3 times daily; titrate dose upward if needed; usual maintenance dose: 900 to 1,800 mg/day divided into 3 doses daily; doses up to 2,400 mg/day divided into 3 doses daily are well tolerated long-term; maximum daily dose: Doses up to 3,600 mg/day have been tolerated in short-term studies. pain relief or the maximum tolerated dose. The maximum daily dose is 3600mg, however in practice many patients do not go over a dose of 1800mg. An example of a dose increase regimen is shown below: Step 4: Gabapentin 300mg morning and 300mg mid-day + 600mg night until tolerated.* Detailed Gabapentin dosage information for adults and children. Includes dosages for Restless Legs Syndrome, Epilepsy and Postherpetic Neuralgia; plus renal, liver and dialysis adjustments. 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). Bone 2002 randomised 19 participants to a maximum of 2400 mg gabapentin daily, or the maximum tolerated dose, with six‐week treatment periods. Using an ITT approach, weekly VAS pain scores were lower at week six only with gabapentin, but not at any other time, nor with categorical pain measures. If you forget a dose, take it as soon as you remember. If it's within 2 hours of the next dose, it's better to leave out the missed dose and take your next dose as normal. Never take 2 doses at the same time. Never take an extra dose to make up for a forgotten one. If you have epilepsy, it's important to take this medicine regularly. The dose may be adjusted and increased gradually based on the individual's response and tolerance. The maximum daily dose is usually not more than 1800 mg per day (600 mg three times per day).For individuals with impaired kidney function or undergoing hemodialysis, the gabapentin dosage may need to be adjusted. Based on available data, it appears that treatment should be started at a dose of 900 mg/d (300 mg/d on day 1, 600 mg/d on day 2, and 900 mg/d on day 3). Additional titration to 1800 mg/d is recommended for greater efficacy. Doses up to 3600 mg/d may be needed in some patients. Diabetic Neuropathy (Off-label) 900 mg/day PO initially; may increase gradually q3Days to 1800-3600 mg/day Administer gabapentin at least 2 hr after each dose to Generally, it is recommended to take gabapentin for at least four to six weeks or at the highest tolerated dose for at least two weeks. However, nerve pain can be a long-term issue, lasting for three or more months. 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. renal elimination (lower maximum doses)1,2 CrCl 30-59 mL/min: maximum 1400 mg per day | CrCl 16-29 mL/min: maximum 700 mg per day CrCl 15 mL/min: maximum 300 mg per day | CrCl < 15 mL/min: reduce dose in proportion to CrCl onset reduction in pain (measured as mean pain scores) is evident in clinical trials by the first week1,6 Gabapentin dosage for neuropathic pain. Gabapentin is most frequently prescribed off-label to treat nerve pain (neuralgia) due to nerve damage (neuropathy), compression, or irritation. Standard gabapentin dosage for adults: 300 to 1200 mg taken three times per day by mouth. Maximum gabapentin dosage for adults: 3600 mg daily in three divided doses. Gabapentin is an anticonvulsive medication that received approval from the US Food and Drug Administration (FDA) in 1993 and has been available in generic form in the USA since 2004. Gabapentin was originally used as a muscle relaxant and an anti-spasmodic. However, it was later discovered that gabapentin has the potential of an anticonvulsive medication and can be used as an adjunct to more Doses of 3600 mg/day have also been administered to a small number of patients for a relatively short duration, and have been well tolerated. Administer NEURONTIN three times a day using 300 mg or 400 mg capsules, or 600 mg or 800 mg tablets. The maximum time between doses should not exceed 12 hours. The typical starting dosage of gabapentin for seizures is 300 mg by mouth three times a day, with or without food. Your prescriber may adjust your gabapentin dosage to up to 600 mg 3 times a day (1,800 mg per day). The maximum gabapentin dosage is 3,600 mg per day, but higher doses are more likely to cause side effects.Restless legs syndrome Start with 100 mg at night, increasing by 100 mg a day until pain is significantly reduced, intolerable adverse effects occur, or a maximum daily dosage of 3600 mg (1200 mg three times a day) is reached [Dworkin, 2007]. Gabapentin b: 100-300 mg at bedtime or 100-300 mg 3 times daily: Increase by 100-300 mg 3 times daily every 1-7 d as tolerated: 3600 mg/d (1200 mg 3 times daily); reduce if impaired renal function: 3-8 wk for tritration plus 2 wkat maximum dose: Pregabalin b: 50 mg 3 times daily or or 75 mg twice daily as tolerated Gabapentin (Neurontin, Gralise, Horizant) is a medicine used to treat partial seizures, nerve pain from shingles and restless leg syndrome. It works on the chemical messengers in your brain and nerves. Gabapentin is from a group of medicines called anticonvulsants.
