How soon to start Tamiflu or Paxlovid after symptoms begin. Here are three things to know. Oseltamivir, sold as Tamiflu, helps most when started within 48 hours of the first symptoms. Baloxavir, sold as Xofluza, is a single-dose option for many people with the same window. People at high risk may still benefit later, so call even if you are past two days. Paxlovid is for adults at higher risk of severe illness and needs to start within five days of the first symptoms. It interacts with many common medicines, including some statins, blood thinners and heart rhythm medicines, so your prescriber will review everything you take. Older age, diabetes, heart or lung disease, obesity, a weakened immune system and pregnancy all make early treatment more valuable. But trouble breathing, chest pain or pressure, confusion, bluish lips or face, or being unable to keep fluids down need emergency care, not an office visit.
