What are intravenous pain-relieving medications?

These medications include:

  • Morphine
  • Demerol (meperidine)
  • Fentanyl
  • Numorphan (generic name oxymorphone)
  • Other options

All of these are "opioids," meaning morphine-like drugs, which work by interfering with pain processing pathways in both the brain and spinal cord.
