My husband had a lot of headache pain, from blood in his brain, they said. He was started out on morphine. It made him nauseous. After a few hours of that they switched him to Fentynl (spelling?) another narcotic IV pain med. That made him nauseous too, but maybe not quite as much as the morphine. They gave him some IV nausea medicine  can't remember the name. That helped. After a day or two of the Fentynl, they put him on Oxycodine (sp?) pills, which made him nauseous and caused some vomiting. The head pain was pretty bad so he stayed on that a few days. After he was discharged, he was still on the Oxyco pills and still had vomiting, so they told us to lay off the Oxyco. He still had alot of pain (headache), but I just gave him Tylenol and Ibuprophen, alternating every 3 hours, for a week or so.By that time the headache was getting a lot better.
