STORAGE: Tablets and capsules should be stored between 15 C to 30 C (59 F to 86 F). Gabapentin solution should be refrigerated between 2 C to 8 C (36 F to 46 F).

PRESCRIBED FOR: Gabapentin is approved for treating seizure disorders and nerve damage from herpes zoster (shingles, postherpetic neuralgia). There are many non-approved uses for gabapentin. These include alcohol withdrawal, cocaine withdrawal, hiccups, restless leg syndrome, hyperhidrosis, headaches, diabetic neuropathy, hot flashes, and fibromyalgia.

DOSING: Gabapentin may be taken with or without food.

The recommended dose for postherpetic neuralgia is 1800 mg daily in 3 divided doses (Neurontin) or 1800 mg once daily (Gralise). Gralise is not interchangeable with other gabapentin products. Seizures are treated with 900-1800 mg/daily in 3 divided doses (Neurontin). Withdrawal of treatment should occur slowly over a week.

DRUG INTERACTIONS: Antacids reduce the concentration of gabapentin in blood. Therefore, gabapentin should be administered 2 hours or more after taking antacids. Morphine significantly increases blood concentrations of gabapentin and may increase central nervous system-related adverse events associated with gabapentin.
