Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear Henry has lymphoma, I know this is a difficult time for your family. Side effects, especially from Lomustine can include bone marrow suppression, but more commonly GI upset signs like vomiting, diarrhea, etc. If the side effects are very severe, please contact your doctor, as we can administer gi protectants as well as anti nausea medications to help lessen the symptoms. My best to all of you.
