paxlovid when to start

Paxlovid should be started as soon as possible after COVID symptoms begin , and no later than 5 days after symptom onset if it’s appropriate for you.

Quick Scoop

  • The official guidance is to start the 5-day Paxlovid course within 5 days of symptoms starting.
  • It’s generally meant for people with mild-to-moderate COVID-19 who are at higher risk of severe illness , so you should contact a clinician promptly after a positive test.
  • Some newer research suggests the sweet spot may be around 3 to 5 days after symptoms begin for reducing viral load and rebound, but the practical rule remains: don’t wait—start within 5 days if prescribed.

What to do

  1. Count from the first day of symptoms , not from when you feel “really sick.”
  1. Get medical advice quickly after testing positive, especially if you’re older or have risk factors.
  1. Take it exactly as prescribed and finish the full 5-day course.

Important note

If you’re asking because you may have COVID now, timing matters a lot, and eligibility also depends on your health history and other medications.
