Upsides

  • 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.
  • Trilafon (perphenazine) can be much cheaper than other medicines.
  • Trilafon (perphenazine) is less likely to cause heart problems or changes in blood pressure.
Downsides

  • You're more likely to gain weight.
  • You can be more sensitive to temperature changes.
