Drug Information:
Movantik (naloxegol) blocks certain effects of opioid medication. An opioid is sometimes called a narcotic. Movantik 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. Movantik 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. You should not use Movantik if you have a blockage in your stomach or intestines. Learn more
