constipation, drug induced
"I've been taking opiate medication for approximately 3 yrs for chronic back pain from an injury/automobile accident my Dr gave me a few sample packs and instructed me #1 25mg tablet of Movantik daily on the second day which was in my normal 4-5 day period so I can't say that it was induced from taking the Movantik anyhow I continued taking it for another 6 days and nothing at all so I felt it was definitely time to go back on the  Amitiza before I stopped all together other than I didn't feel any other symptoms."
