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.
  • Cymbalta (duloxetine) may help relieve nerve pain from diabetes and other forms of chronic pain.
  • Cymbalta (duloxetine) has several uses, which may be good for people with multiple conditions.
  • Available as a generic, which is cheaper.
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.
  • Cymbalta (duloxetine) may not be a good option if you're a heavy drinker, or have liver or kidney problems.
  • Cymbalta (duloxetine) can increase high blood pressure.
  • Like most antidepressants, Cymbalta (duloxetine) can cause higher risk of suicidal thoughts and behavior for people aged 24 and younger.
