My husband had Y90 placed in his liver on 9/11/2024 . He is very sensitive to medications and we actually discovered he is allergic to must chemo meds, so when they said “ most people feel like they have the flu for a couple of days and feel a bit off for about 2 weeks “ I in my head planned for 3-4 weeks of him not feeling well as he’s also a very slow metabolizer of medication . I was so very pleased it was about 4 days of laying low and then he felt good and it just got better from there. It also works! Hope this is helpful and best of luck Cat
