Side Effects

Side effects from gabapentin include:

  • Fatigue or drowsiness.
  • Dizziness and lightheadedness, especially during the first couple of weeks of treatment.
  • Swelling of the hands and feet.
  • Rash.
  • Nausea.

Side effects are less likely when the dose is gradually increased and when medicine is taken with meals or at bedtime.

The U.S. Food and Drug Administration (FDA) has issued a warning on antiseizure medicines and the risk of suicide and suicidal thoughts. The FDA does not recommend that people stop using these medicines. Instead, people who take antiseizure medicine should be watched closely for warning signs of suicide. People who take antiseizure medicine and who are worried about this side effect should talk to a doctor.

See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
