Entereg, also known by its generic name alvimopan, is a medication used to help manage postoperative ileus in patients who have undergone bowel surgery. Postoperative ileus is a condition where the normal movement of the intestines is slowed or stopped after surgery, leading to symptoms such as bloating, nausea, and constipation.

Entereg works by blocking certain receptors in the intestines, which helps to speed up the recovery of normal bowel function after surgery. This can help reduce the time it takes for patients to start eating and drinking again, as well as decrease the risk of complications such as bowel obstruction.

It is important to note that Entereg is only approved for short-term use in hospitals and should not be used for more than 15 doses. It is typically given as a single dose before surgery and then continued for a few days after the procedure.

As with any medication, there are potential side effects to be aware of when taking Entereg. These can include nausea, vomiting, diarrhea, and abdominal pain. It is important to discuss any concerns or questions with your healthcare provider before starting this medication.

Overall, Entereg can be a helpful tool in managing postoperative ileus and promoting a quicker recovery after bowel surgery. If you have any questions about Entereg or think it may be a good option for you, be sure to speak with your healthcare provider for more information.
