Possible off-label uses for Gralise may include treating epilepsy, bipolar disorder, and migraines.
What Is Gralise Used For?Gralise™ (extended-release gabapentin) is a prescription medication used to treat postherpetic neuralgia (nerve pain that occurs after a case of shingles).
About one million people develop shingles each year, and a number of them experience a complication called postherpetic neuralgia. This is pain that is present in the affected area for months, or even years, after the shingles rash has healed. The most bothersome symptom of postherpetic neuralgia is pain. The pain can result in an inability to perform daily tasks of living and may be described as:
- Sharp, electric-like jabs
Postherpetic neuralgia treatment usually involves medication. Gralise is one of the medications approved to treat the pain associated with postherpetic neuralgia.
Notably, Gralise is not approved to treat epilepsy (another gabapentin medication, Neurontin®, is approved for epilepsy treatment).
