- Antivirals like Tamiflu and Xofluza can shorten the flu by about one to two days, reduce symptom severity and some complications, and work best when started within 48 hours; they can also be used to prevent illness after a known exposure.
- Not everyone needs antivirals—many healthy people recover with rest, fluids, and fever reducers—but treatment is recommended for people who are hospitalized or have severe illness and for high-risk groups (young children, people 65+, pregnant people, immunocompromised individuals, and those with chronic conditions).
- Side effects are usually mild (mainly nausea) and serious harms are rare, and many scary online claims are misleading—Tamiflu has not been shown to routinely cause hallucinations and star anise tea is not a substitute; Xofluza is a one‑dose option that may reduce contagiousness but is more expensive and has less data in some populations.
