pain
"I was given 100 micrograms every hour plus 50 micrograms every 30 minutes as a push button in a drip for cancer pain and it worked great. After the Morphine dose was above 20mg every 4 hours I was given the drip. It worked great for pain and had very little side effects, only constipation but that was because I was on it for 30 days.
I would strongly suggest for any type of severe pain and/or cancer pain if morphine or Dilaudid isn't working or isn't tolerable."
