Adults, normal: 5 to 7 hours; increased half-life with decreased renal function; anuric adult patients: 132 hours; adults during hemodialysis: 3.8 hours. <3% In CrCl <30 mL/minute, half-life is approximately 52 hours (immediate release). The effective dose of gabapentin in patients 3 to 4 years of age is 40 mg/kg/day, given in three divided doses. The effective dose of gabapentin in patients 5 to 11 years of age is 25 mg/kg/day to 35 mg/kg/day, given in three divided doses. Dosages up to 50 mg/kg/day have been well tolerated in a long-term clinical study. What dosage strengths and forms does gabapentin come in? Gabapentin is available as: Gabapentin tablets. It’s available as 300- and 600-milligram tablets (Gralise) and 600- and 800-milligram tablets (Neurontin or generic gabapentin). Gabapentin oral solution. Gabapentin is eliminated from the systemic circulation by renal excretion as unchanged drug. Gabapentin is not appreciably metabolized in humans. Gabapentin elimination half-life is 5 to 7 hours and is unaltered by dose or following multiple dosing. Gabapentin elimination rate constant, plasma clearance, and renal clearance are directly Starting Dose: ranges from 10 to 15 mg/kg/day in 3 divided doses. Effective Dose: reached by upward titration over a period of approximately 3 days. The effective dose of gabapentin in patients 5 years of age and older is 25 to 35 mg/kg/day and given in divided doses (three times a day). Gabapentin is not appreciably metabolized in humans. Gabapentin elimination half-life is 5 to 7 hours and is unaltered by dose or following multiple dosing. Gabapentin elimination rate constant, plasma clearance, and renal clearance are directly proportional to creatinine clearance. Additional smaller gabapentin dosage groups (600 mg/day, N=53; 1,800 mg/day, N=54) were also studied for information regarding dose response. Responder rate was higher in the gabapentin 1,200 mg/day group (16%) than in the placebo group (8%), but the difference was not statistically significant. Effective Dose: Reached by upward titration over a period of approximately 3 days; the effective dose in patients 5 years of age and older is 25 to 35 mg/kg/day in divided doses (3 times a day). The effective dose in pediatric patients ages 3 and 4 years is 40 mg/kg/day and given in divided doses (3 times a day). Additional smaller gabapentin dosage groups (600 mg/day, N=53; 1800 mg/day, N=54) were also studied for information regarding dose response. Responder rate was higher in the gabapentin 1200 mg/day group (16%) than in the placebo group (8%), but the difference was not statistically significant. The established therapeutic dosing for gabapentin in neuropathic pain trials is 1800-3600 mg/day in 3 divided dose s 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. Additional smaller gabapentin dosage groups (600 mg/day, N=53; 1,800 mg/day, N=54) were also studied for information regarding dose response. Responder rate was higher in the gabapentin 1,200 mg/day group (16%) than in the placebo group (8%), but the difference was not statistically significant. Administer gabapentin three times a day using 300 mg or 400 mg capsules. The maximum time between doses should not exceed 12 hours. The starting dose range is 10 mg/kg/day to 15 mg/kg/day, given in three divided doses, and the recommended maintenance dose reached by upward titration over a period of approximately 3 days. The no-effect level was 500 mg/kg/day or approximately ½ of the human dose on a mg/m 2 basis. When rats were dosed prior to and during mating, and throughout gestation, pups from all dose groups (500, 1000, and 2000 mg/kg/day) were affected. These doses are equivalent to less than approximately 1 to 5 times the maximum human dose on a mg/m 2 Adults— At first, 300 milligrams (mg) as a single dose in the evening. Your doctor may adjust your dose as needed and tolerated. However, the dose is usually not more than 1800 mg per day. Children—Use and dose must be determined by your doctor. For adults, your gabapentin dosage varies depending on your medical conditions and which form you’re taking. The maximum dosage is 3,600 mg per day. For children, the dosage is based on age and body weight. 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 Dosage for Pain (mg) Gabapentin Dosage for Seizures (mg) 💡 Tip; Up to 10 lbs: 50-100 mg every 12 hours: 50 mg every 8-12 hours: Use for small breeds like Chihuahuas or Pomeranians. 10-20 lbs: 100 mg every 8-12 hours: 100 mg every 8 hours: Great for dogs like Shih Tzus or Dachshunds. 20-50 lbs: 100-300 mg every 8-12 hours: 200 mg How is gabapentin supplied (dosage forms)? Gabapentin is available as Gralise, Neurontin, and generic gabapentin in the following dosage forms that are taken by mouth. 100 mg, 300 mg, 400 mg Peak plasma concentrations of gabapentin in rats receiving the high dose of 2,000 mg/kg/day were more than 10 times higher than plasma concentrations in humans receiving 1,800 mg per day and in rats receiving 1,000 mg/kg/day peak plasma concentrations were more than 6.5 times higher than in humans receiving 1,800 mg/day. Gabapentin is eliminated from the systemic circulation by renal excretion as unchanged drug. Gabapentin is not appreciably metabolized in humans. Gabapentin elimination half-life is 5 to 7 hours and is unaltered by dose or following multiple dosing. Gabapentin elimination rate constant, plasma clearance, and renal clearance are directly
