Actually I have had acute pancreatitis caused by medication, twice. It was not any of the medications you listed though. The first time I had it I had pretty severe pain for a couple of weeks before I finally went to a doctor (I hate going to doctors). The doctor said there wasn't anything wrong with me but my mom insisted that they did a blood test and they found out I had pancreatitis. None of the doctors would believe me that the medication was the cause of it, so a couple of months later they perscribed a similar medication and sure enough, I had pancreatitis again. That time I had to be hospitalized. Actually I had it so severe that it looked like I had a tumor on my pancreas...thought I was going to die from pancreatic cancer at that point...had lots of tests and found out eventually that it was just a localized area of severe pancreatitis. I hope you are able to find out what is wrong, if you suspect it is pancreatitis get in soon and make sure you get a blood test.
