constipation, drug induced
"Please, please read this before trying any prescription for chronic constipation due to opioid use.  Due to a back injury, I have been taking opioids for over 10 years.  I had chronic constipation with no relief with anything.  Then I read another person's experience with magnesium.  The type of magnesium you take is important.  You want to take one that has low absorption, so that it will pass right through.  I went from having a bowel movement once a week or week and a half to having one daily.  I take 1-250mg magnesium oxide and 1 docusate sodium (non-stimulant stool softener) twice a day (same dosage for the last 9 years).  You can find these over-the-counter  in any drugstore.  Unfortunately, a physician won't tell you this."
