Hi. My mom was put on Ethyol and the only thing I can add is to make sure you let the RO and nurses know any and all side effects that Buzz encounters. Unfortunately, although we kept telling the RO and nurses that my mom was vomiting all day, they thought that if it was related to the Ethyol she should be vomiting right after the injection/treatment or shortly thereafter. In reality, my mom would not start vomiting until about 4 hours post injection and then would vomit at least 3-4 more times a day. Once she was taken off of the Ethyol it got SO much better. Other than that, just make sure he has tons of liquid. Someone responded to one of my posts with a GREAT explanation of how ethyol should be admistered, including the liquids, and I would suggest you read that. It was incredibly informative. Good luck! My thoughts are with you.
