Dilaudid
"I developed severe pancreatitis and hepatitis due to gallstones. They tried morphine  first, but it makes me vomit even if they give me Zofran, Phenergan or Reglan with it. I'm allergic to many medications and latex. My only previous experience with painkillers was codeine for a severe cough and Percocet for a gynecological issue. I had an anaphylactic reaction to the Percocet. Not fun. So they decided to try Dilaudid on me - at least if I had a bad reaction to it, they could treat me immediately. I was so grateful! Complete pain relief and no vomiting. No side effects either nor like I was on anything, it just made the pain stop. IV Dilaudid worked within 30 seconds. They gave me pills to take home, the pills take about 30 minutes."
