What is naloxegol?

Naloxegol blocks certain effects of opioid medication. An opioid is sometimes called a narcotic.

Naloxegol reduces constipation caused by opioid (narcotic) pain medicine used to treat severe chronic pain. Naloxegol works by treating constipation without reducing the pain-relieving effects of the narcotic.

Naloxegol is used in people who have been taking narcotic pain medicine for at least 4 weeks, to treat chronic pain that is not caused by cancer.
