As the total dose reduces, keep the percentage dose reduction the same rather than the amount you are reducing the dose by, e.g. at 3,600 mg gabapentin daily, a 10% reduction is 360 mg, while at 1,200 mg daily, a 10% reduction is 120 mg (i.e. you would not reduce the latter dose by 360 mg) The starting dose is 900mg/day (given as 300mg 3 times daily) and increased if necessary based on response. The maximum daily dose is 3600mg. Dosage may need to be adjusted in those with impaired renal function. Patients on haemodialysis should start on a loading dose of 300-400mg, followed by 200-300mg after every 4 hours of haemodialysis. The effective dose of gabapentin is 25 mg/kg/day to 35 mg/kg/day given in divided doses (3 times a day) as described in Table 1. Initial titration to an effective dose can take place over 3 days by giving 10 mg/kg/day on Day 1, 20 mg/kg/day on Day 2, and 30 mg/kg/day on Day 3. Thereafter, the dose Concurrent treatment with CNS depressants (eg, opioids) and gabapentin or pregabalin should be avoided. 5,6 In the event that these medicines have to be used together, the patient must be closely observed for signs of CNS depression, such as somnolence, sedation and respiratory depression, and the doses adjusted as needed. 5 For neuropathic pain, assess at each dose level before titrating upwards. The optimal dose varies from 100mg at night to 1200mg three times per day, depending on age and concomitant medical conditions. Some people may manage a higher starting dose of 300mg three times daily, titrated by 300mg every 2-3 days. If gabapentin does not provide The New Zealand Formulary. The NZF is an independent resource providing healthcare professionals with clinically validated medicines information and guidance on best practice, enabling healthcare professionals to select safe and effective medicines for individual patients. Both medicines have similar efficacy, however, in practice, pregabalin may be preferrable for some people as lower doses can be used , dosing is typically less frequent and the titration period is often faster compared to gabapentin. 1 Pregabalin displays a linear dose-response relationship, where plasma concentrations increase in proportion to In controlled clinical trials, the effective dose range was 900 mg/day to 1800 mg/day given in divided doses (three times a day). Therapy may be initiated by administering 300 mg of gabapentin three times a day on Day 1 or by titrating the dose as described below. Approximately 1300 people in New Zealand are taking gabapentin for the management of epilepsy. 8 General practitioners do not need to notify the New Zealand Transport Association (NZTA) if patients using gabapentin for epilepsy change from one brand to another. to treat epilepsy by preventing some types of seizures. In Aotearoa New Zealand, gabapentin is available as 100 mg, 300 mg and 400 mg capsules. The dose of gabapentin is different for different people. Your doctor will usually start you on a low dose and increase the dose over a few days. Gabapentin bioavailability is not dose proportional, i.e. as dose is increased, bioavailability decreases. A 400 mg dose, for example, is about 25% less bioavailable than a 100 mg dose. Over the recommended dose range of 300 mg to 600 mg three times a day, however, the differences in bioavailability are not large, and bioavailability is about 60%. maximum daily dose of 300mg bd.10 As expected, pregabalin doses at the higher end of the dose range are more conservative than other published algorithms.3,9 Options for switching There are three approaches described in the literature: 1. Stop/start: Take the last dose of gabapentin at night and start the target dose of pregabalin the following In controlled clinical trials, the effective dose range was 900 mg/day to 1800 mg/day given in divided doses (three times a day). Therapy may be initiated by administering 300 mg of gabapentin three times a day on Day 1 or by titrating the dose as described below. to 2018, gabapentin was funded with Special Authority approval and pregabalin was not funded. Since the Figure 1: Number of patients per 1,000 dispensed gabapentin and pregabalin in New Zealand from 2015 to 2020.16 N.B. In 2018, both gabapentin and pregabalin were funded without restriction; prior to 2018, gabapentin was funded with Gabapentin has been associated with a rare risk of severe respiratory depression even without concomitant opioid medicines. Dose adjustments may be appropriate in these patients. Supplied As Oral: Gabapentin 100mg/mL (prepared by pharmacy) Dosage Start only on the advice of Paediatric Neurology Day 1 - 2.5 mg/kg/dose once a day Discontinuation symptoms reported include insomnia, nausea, anxiety, pain, and sweating.4 Determining dose equivalence between gabapentin and pregabalin is complicated by gabapentin’s nonlinear bioavailability, in contrast to pregabalin’s linear bioavailability.6 Gabapentin’s bioavailability ranges from 80% with 100mg tds6 to 35% with 1 Take gabapentin regularly as directed with a glass of water. You can take it with or without food. What if you forget a dose? Take the missed dose as soon as possible and continue as directed. Can you take other medicines? Some medicines available without a prescription may react with gabapentin including: at least 2 hours before or after taking gabapentin.5 DOSE AS PER RENAL FUNCTION Dose adjustments are necessary for people with poor renal function because gabapentin is cleared renally. Refer to the following table for maximum dosing recommendations.1,5 GABAPENTIN – DOES THE DOSE FIT? 1 4PROVIDE CLEAR DOSING AND TITRATION GUIDELINES Gabapentin is an anticonvulsant that is used for certain types of epilepsy for people who have not achieved adequate control, or have experienced unacceptable side effects with standard anti- New Zealand Consumer Medicine Information .
