Gabapentin is FDA-approved for certain conditions, like neuropathic pain and seizures, but it is also widely used off-label for a variety of other medical issues. Off-label use means prescribing the medication for conditions not specifically approved by regulatory agencies. Doctors often prescribe gabapentin off-label to treat conditions such as:
- pain from diabetic neuropathy, which is numbness or uncomfortable tingling caused by nerve damage from diabetes
- nerve pain in the neck and back from conditions such as sciatica, a painful compression of the sciatic nerve
- hot flashes, which are sudden feelings of heat and sweating that can happen in women after menopause and in those being treated for breast cancer
- mood disorders such as anxiety
- alcohol addiction.
