Upsides
  • Originally used to treat epilepsy (partial seizures), but now it primarily treats neuropathic pain that's caused by nerve stimulation or damage.
  • Studies show it's most effective for nerve pain from diabetes, shingles, and fibromyalgia (a painful muscle condition).
  • It's available as a generic, so it's less expensive than similar medications.
  • Effective at relieving psychotic symptoms, manic episodes, and agitation in people with schizophrenia and bipolar disorder.
  • Less likely to cause heart problems than other antipsychotics.
  • Less likely to cause movement problems compared to older antipsychotics.
Downsides
  • Neurontin (gabapentin) can cause some side effects, including memory problems, drowsiness, dizziness, or confusion. There is a higher risk for these side effects if you drink alcohol, so it might not be the best medication for heavy drinkers.
  • You can't skip or miss doses since suddenly stopping Neurontin (gabapentin) can cause seizures.
  • More likely to cause weight gain and increase cholesterol or blood sugar compared to other antipsychotics.
  • Might make you more sleepy than some antipsychotics.
  • Mild risk of Extrapyramidal Symptoms (EPS): Movement disorders that include stiffness, tremor, restlessness, and slow, repetitive movements you can't control.
  • You may need routine blood tests to check how the medicine is affecting your body..
