I had an endoscopy and found out I have a large duodenal ulcer with partial outlet obscrtuction.Can I take Amitiza with this ulcer?I was supposed to have a colonoscopy but I couldn't get completely clear.I was put on a drug to help heal the ulcer and a proton pump inhibitor.I just want to know if it is safe to amitiza.I am on opiods so I need it.
