Question: what antibiotic is used to treat flu in adults?
Answer: The CDC recommends baloxavir marboxil (Xofluza), oseltamivir (Tamiflu), peramivir (Rapivab), and zanamivir (Relenza) for flu. They are most effective when given within 48 hours after symptoms start to appear. These flu drugs can decrease the duration of the flu by one to two days if used within this early time period.
