Gabapentin capsules are indicated for: Management of postherpetic neuralgia in adults. Adjunctive therapy in the treatment of partial onset seizures, with and without secondary generalization, in adults and pediatric patients 3 years and older with epilepsy

How it works

The exact way gabapentin works for pain and seizures is unknown. It is related to the brain chemical GABA but does not act on GABA. It binds to part of certain calcium channels, but how that helps is unknown.

Source text (exact source wording)
The precise mechanisms by which gabapentin produces its analgesic and antiepileptic actions are unknown. Gabapentin is structurally related to the neurotransmitter gamma-aminobutyric acid (GABA) but has no effect on GABA binding, uptake, or degradation. In vitro studies have shown that gabapentin binds with high-affinity to the α2δ subunit of voltage-activated calcium channels; however, the relationship of this binding to the therapeutic effects of gabapentin is unknown.

Dosage: adults

For nerve pain after shingles, the dose may start at 300 mg on Day 1, 600 mg/day on Day 2 and 900 mg/day on Day 3, then be raised as needed up to 1,800 mg/day. For epilepsy in patients 12 and older, the starting dose is 300 mg three times a day, with a maintenance dose of 300 mg to 600 mg three times a day. Doses should not be more than 12 hours apart. It can be taken with or without food, swallowed whole with water. Any dose reduction or stop should be gradual over a minimum of 1 week. Dosing is set by the prescriber.

In adults with postherpetic neuralgia, gabapentin capsules may be initiated on Day 1 as a single 300 mg dose, on Day 2 as 600 mg/day (300 mg two times a day), and on Day 3 as 900 mg/day (300 mg three times a day). The dose can subsequently be titrated up as needed for pain relief to a dose of 1,800 mg/day (600 mg three times a day). Epilepsy, patients 12 years of age and above: The starting dose is 300 mg three times a day. The recommended maintenance dose of gabapentin capsules are 300 mg to 600 mg three times a day. Dosages up to 2,400 mg/day have been administered in long-term clinical studies. Administer gabapentin capsules three times a day using 300 mg or 400 mg capsules. The maximum time between doses should not exceed 12 hours. Administer gabapentin capsules orally with or without food. Gabapentin capsules should be swallowed whole with water. If the gabapentin capsules dose is reduced, discontinued, or substituted with an alternative medication, this should be done gradually over a minimum of 1 week (a longer period may be needed at the discretion of the prescriber).

Dosage: children

For epilepsy in children 3 to 11 years the starting dose is 10 mg/kg/day to 15 mg/kg/day in three divided doses. The maintenance dose is 40 mg/kg/day for ages 3 to 4 and 25 mg/kg/day to 35 mg/kg/day for ages 5 to 11. Safety and effectiveness for nerve pain after shingles in children, and for seizures under age 3, have not been established.

Kidney
The dose must be lowered in patients 12 and older with reduced kidney function or on hemodialysis. For example, the total daily dose range is 900 to 3,600 mg/day at a creatinine clearance of 60 or more and 400 to 1,400 mg/day at more than 30 to 59. Below 15, the daily dose is reduced in proportion to creatinine clearance. It has not been studied in children under 12 with kidney problems.

Pregnancy and breastfeeding

Pregnancy
Available human data have not shown an increased risk of major birth defects or miscarriage. Animal studies showed harm to developing offspring at doses similar to or lower than those used clinically. Long use with opioids near delivery may raise the risk of neonatal withdrawal. A pregnancy registry exists (1-888-233-2334).

The totality of available data from published prospective and retrospective cohort studies pertaining to gabapentin use during pregnancy has not indicated an increased risk of major birth defects or miscarriage. In nonclinical studies in mice, rats, and rabbits, gabapentin was developmentally toxic (increased fetal skeletal and visceral abnormalities, and increased embryofetal mortality) when administered to pregnant animals at doses similar to or lower than those used clinically. Postmarketing data suggest that extended gabapentin use with opioids close to delivery may increase the risk of neonatal withdrawal versus opioids alone.

Side effects

Common
For nerve pain after shingles, the label's most common reactions were dizziness, somnolence (sleepiness) and peripheral edema (swelling). For epilepsy in patients over 12 they were somnolence, dizziness, ataxia (poor coordination), fatigue and nystagmus (unusual eye movements). In children 3 to 12 they were viral infection, fever, nausea and/or vomiting, somnolence and hostility. For example, in the shingles-pain trials dizziness occurred in 28% of gabapentin patients versus 8% on placebo and somnolence in 21% versus 5%.

Source text (exact source wording)
Respiratory depression and sedation, sometimes resulting in death, have been reported following coadministration of gabapentin with opioids (e.g., morphine, hydrocodone, oxycodone, buprenorphine). Coadministration of gabapentin with hydrocodone decreases hydrocodone exposure. When gabapentin is administered with morphine, patients should be observed for signs of CNS depression, such as somnolence, sedation and respiratory depression.
Other sedating drugs may add to sleepiness; patients should be watched for CNS depression.
