Pain
"This medicine is sadly being used less and less in the emergency rooms. I am tolerant to morphine and allergic to many other pain medications. Demerol not only stops the pain but it stops it for a good 14-16 hours  if I am given 100 mg IM with 50 mg Gravol. I walk out of the ER on my own like I took a Tylenol. Takes a few hours to kick in but when it does I usually get the best 10-12 hours of sleep which helps decrease the pain since I can rest and let my muscles be at rest. I pray they do not discontinue this medicine. It helps many people for break through pain where others don&#039;t, especially for use people with CRPS and Fibromyalgia. It&#039;s a miracle medicine for me. I use this about 3 to 4 times a year if needed for breakthrough pain lasting more than 72 hours."
