Remdesivir outpatient therapy is given as an IV infusion within how many days of symptom onset?

• A. 3 days
• B. 5 days
• C. 7 days
• D. 10 days

Answer: (C)

Remdesivir works best when viral replication is still active, which is in the first week of illness. For non-hospitalized patients at high risk who qualify for outpatient antiviral therapy, the recommended window to start IV remdesivir is within seven days of symptom onset. The usual outpatient plan is a 3-dose course given over 3 days (day 1, then days 2–3). Starting later than seven days has less proven benefit because the disease process may be driven more by inflammation than by ongoing viral replication.
