A third study compared gabapentin 900 mg/day, in three divided doses (N=111), and placebo (N=109). An additional gabapentin 1200 mg/day dosage group (N=52) provided dose-response data. A statistically significant difference in responder rate was seen in the gabapentin 900 mg/day group (22%) compared to that in the placebo group (10%). e.g. elderly, renal impairment, breast feeding which may affect the suitability for prescribing or the dosage. Gabapentin usually starts at 300mg once a day (at night) and titrates upwards, adjusted according to response to a maximum of 3600mg daily in divided doses. Evidence suggests that a minimum of 1200mg is usually needed and doses may need to Detailed Gabapentin dosage information for adults and children. Includes dosages for Restless Legs Syndrome, Epilepsy and Postherpetic Neuralgia; plus renal, liver and dialysis adjustments. INTRODUCTION. Chronic pain is one of the most common reasons that patients seek medical attention. Chronic pain results from combined biologic, psychologic, and social factors, and most often requires a multifactorial approach to management. For the focus on very old people, who are often affected by malnutrition, sarcopenia and higher risk of falls, a different approach in the treatment of pain is required. In these cases, physicians should prefer lower dosages, alternative medications or nonpharmacological therapies. How to take Gabapentin Gabapentin needs to be gradually increased over a period of time until a maximum daily dose of 600mgs three times a day is reached. Follow the table below taking from 1 tablet a day to a maximum of 2 tablets three times a day: Morning Afternoon Evening Step 1 300mg Step 2 300mg 300mg Step 3 300mg 300mg 300mg The maximum dosage of gabapentin is 3,600 mg per day. However, doses greater than 1,800 mg per day haven’t been shown to be more effective than lower doses. The capsules, tablets, and solution can be taken with or without food. Dosages up to 2400 mg/day have been well tolerated in long-term clinical studies. Doses of 3600 mg/day have also been administered to a small number of patients for a relatively short Slow titration (suitable if the person is elderly, frail, or has experienced adverse effects with higher doses). 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]. Maximum dose: The maximum dose for elderly patients may be lower than for younger adults, depending on their overall health and kidney function. Frequency of administration : Dividing the daily dose into multiple smaller doses can help reduce side effects and maintain steady blood levels of the medication. Child 6–11 years 10 mg/kg once daily (max. per dose 300 mg) on day 1, then 10 mg/kg twice daily (max. per dose 300 mg) on day 2, then 10 mg/kg 3 times a day (max. per dose 300 mg) on day 3; usual dose 25–35 mg/kg daily in 3 divided doses, some children may not tolerate daily increments; longer intervals (up to weekly) may be more appropriate, daily dose maximum to be given in 3 divided It may be reasonable to start older adults on a low dose of gabapentin, which can be effective to treat pain while exposing patients to a lower risk of adverse mental status side effects of gabapentin (dizziness, drowsiness and confusion) [7]. Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of gabapentin for treating partial seizures in children 3 years of age and older. However, safety and efficacy have not been established in children younger than 3 years of age. -Initial dose: 300 mg orally on day one, 300 mg orally 2 times day on day two, then 300 mg orally 3 times a day on day three -Titrate up as needed for pain relief -Maximum dose: 1800 mg per day (600 mg orally 3 times a day) Disclaimer: This generalized information is a limited summary of diagnosis, treatment, and/or medication information. It is not meant to be comprehensive and should be used as a tool to help the user understand and/or assess potential diagnostic and treatment options. 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. A third study compared gabapentin 900 mg/day, in three divided doses (N=111), and placebo (N=109). An additional gabapentin 1,200 mg/day dosage group (N=52) provided dose-response data. A statistically significant difference in responder rate was seen in the gabapentin 900 mg/day group (22%) compared to that in the placebo group (10%).

Multiple comorbidities and the risk of polypharmacy in the elderly make it a challenge to determine the appropriate drug, dosage, and maintenance of therapy. Opioids are the most commonly used agents for this purpose in the elderly. Doses of 3,600 mg/day have also been administered to a small number of patients for a relatively short duration, and have been well tolerated. Administer gabapentin three times a day using 300 mg or 400 mg capsules. The maximum time between doses should not exceed 12 hours. Pediatric Patients Age 3 to 11 years
