What Is Gabapentin and How Does It Work?
Gabapentin is a prescription drug most commonly prescribed to relieve nerve pain following shingles in adults, treating the pain of post herpetic neuralgia. Gabapentin belongs to a class of drugs known as anti-seizure drugs.
Take gabapentin by mouth as directed by your doctor, usually once a day with the evening meal. The dosage is based on your medical condition and response to treatment.
Swallow gabapentin whole. Do not crush or chew sustained-release tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split sustained-release tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.
During the first 2 weeks of treatment, your doctor may gradually increase your dose so your body can adjust to the medication.
Gabapentin is available under the following different brand names: Neurontin and Gralise.

Initial: 300 mg orally every 8 hours.
May increase up to 600 mg orally every 8 hours; up to 2400 mg/day administered and tolerated in clinical studies; up to 3600 mg administered for short duration and tolerated
Post herpetic Neuralgia
Neurontin
Day 1: 300 mg orally once per day.
Day 2: 300 mg orally every 12 hours.
Day 3: 300 mg orally every 8 hours.

Dosing Modifications:
Renal impairment (Neurontin)
Creatinine clearance greater than 60 mL/min: 300-1200 mg orally twice daily

Creatinine clearance 15-29 mL/min: 200-700 mg once per day
Creatinine clearance less than 15 mL/min: 100-300 mg once per day
Hemodialysis (Creatinine clearance less than 15 mL/min):
Administer supplemental dose (range 125-350 mg) post hemodialysis, after each 4 hour dialysis interval; further dose reduction should be in proportion to Creatinine clearance (a Creatinine clearance of 7.5 mL/min should receive one-half daily post hemodialysis dose)
Renal impairment (Gralise):
Creatinine clearance is greater than or equal to 60 mL/min: 1800 mg daily with evening meal
Creatinine clearance 30-59 mL/min: 600-1800 mg daily with evening meal
