- you have low potassium levels in the blood
- you have not yet had a bowel movement after recent surgery or if you have abnormal bowel function
- you have obstructive bowel disease, constipation, or are at risk of constipation or impaction (eg, a history of impaction, chronic constipation, inflammatory bowel disease, ischemic colitis, previous bowel surgery, a bowel blockage)
- the patient is a newborn with decreased bowel activity
- you are taking magnesium hydroxide or sorbitol
Contact your doctor or health care provider right away if any of these apply to you.
