Feces, or BMs, get hard and dry. When starting medicines like morphine, hydromorphone, or fentanyl, you will need medicine to maintain regular bowel movements. If your doctor or nurse does not suggest medicine for your bowels, ask about it. It is very important to tell the doctor or nurse if your bowels have not moved for more than two days. Severe constipation causes pain, nausea, and vomiting and can be dangerous.
Constipation is a potential problem as long as a person takes opiates.
As doses of opiate medicines are increased, untreated constipation gets worse. There are easy steps to take to prevent constipation, such as drinking more water and fruit juices, eating more fiber, and exercising. People sometimes stop taking medicines that can help pain because constipation is not well managed. Don't let this happen to you. Take prescribed medications to prevent constipation as directed.
