GABAPENTIN
Formoral.solid
Peripheral neuropathic pain, immediate-release: Day 1, 300 mg orally once; Day 2, 300 mg twice daily; Day 3, 300 mg three times daily; then increase in 300 mg/day steps every 2-3 days as needed, up to 1800 mg/day in three divided doses. - As directed; the minimum time to reach 1800 mg/day is one week. Reassess response before increasing further or referring, and stop gradually over at least 1 week.
The formulary's paediatric gabapentin dosing is for epilepsy with partial-onset seizures, not for pain, and is not reproduced here.

Gabapentin is a standard first-line neuropathic agent for phantom limb pain, dosed and titrated as for other peripheral neuropathic pain syndromes.
- Discontinue gradually over a minimum of 1 week, whatever the indication.
- Reduce the dose in renal impairment: total daily dose 400 to 1400 mg divided twice daily at CrCl 30-59 mL/min, and 200 to 700 mg once daily at CrCl 15-29 mL/min.
- Do not leave more than 12 hours between doses; the total daily dose is divided into three.
- The formulary gives this dose for peripheral neuropathic pain in adults (painful diabetic neuropathy, post-herpetic neuralgia). It carries no dose for phantom limb pain — using it there is extrapolation, not formulary guidance.
- Sedation and dizziness are common, especially at initiation - caution with driving or operating machinery.
- Reduce dose in renal impairment.
- Taper gradually if stopping - do not withdraw abruptly, over a minimum of 1 week.
- Check the stump/wound for infection in a recent amputee before attributing pain to phantom limb syndrome.
- Refer to pain management or rehabilitation if pain does not respond to standard titration.
