constipation, drug induced
"I take Dilaudid because I am living with Multiple Sclerosis and have severe muscle spasms. Unfortunately, the Dilaudid has started making me constipated - so my doctor prescribed me Relistor Injections - 12mg (the higher dose - it depends on your weight).

I took this medication for the first time this morning because I had not had a bowel movement in five days. I did the injection (beware, it burns when injecting!) and went on with my day. Within ten minutes (I'm not kidding) I had to use the restroom. Success! That's the good part. After my successful bowel movement came terrible abdominal pain. I mean, it wasn't like, "I have to go to the ER" terrible, but it was significant enough that I am mentioning it. Overall, a good drug."
