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.
  • Lowers the frequency of seizures, especially for people with tonic-clonic and partial seizures.
  • First-choice option for trigeminal neuralgia (nerve pain involving the face, head, and neck), and can relieve other types of nerve pain.
  • Equetro is helpful in stabilizing mood for people with bipolar disorder.
  • Available as a generic in many forms: pill, extended-release pill, suspension, and chewable tablet.
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.
  • Takes several weeks to feel the full effects.
  • Interacts with many other medicines and supplements.
  • Higher risk of skin reactions compared to other antiepileptic medicines, ranging from mild to life-threatening rash.
  • Requires routine blood tests to see how the medicine is affecting your body.
  • Can't take the suspension form with other liquid medications.
