- How does Paxlovid work? Paxlovid is an antiviral therapy that consists of two separate medications packaged together. When you take your three-pill dose, two of those pills will be nirmatrelvir, which inhibits a key enzyme that the COVID virus requires in order to make functional virus particles.
- When should I take Paxlovid? You have to take Paxlovid within five days of developing symptoms. Like all antivirals, Paxlovid works best early in the course of an illness—in this case, within the first five days of symptom onset, says Jeffrey Topal, MD, a Yale Medicine infectious diseases specialist who is involved in determining COVID-19 treatment protocols for Yale New Haven Hospital patients.

Like other antivirals, Paxlovid is designed to stop a virus from making copies of itself. Limiting the number of copies helps the immune system fight off the virus. Made by Pfizer, Paxlovid is a combination of two drugs: ritonavir and nirmatrelvir. Nirmatrelvir, an oval, pink pill, is a so-called protease inhibitor – the same type of drug that turn...
Paxlovid is given in a five-day course with three pills taken twice a day. Most people report feeling better by the second or third day on the drug. Pfizer only studied the medication for the full five days, so people should take them as prescribed, said Dr. Aida Habtezion, Pfizer's chief medical officer.
Paxlovid is given only by prescription and can be administered by physicians, pharmacists, advanced practice registered nurses, and physician assistants who are licensed or authorized under state law to prescribe antivirals. The medication is available at pharmacies nationwide, and the government sponsors a "test-to-treat" program in various locati...
Anyone aged 12 and older, has symptoms and is at high risk for severe disease is eligible to receive a free course of the medication, funded by the government.

One side effect commonly attributed to Paxlovid is "rebound" — testing positive for COVID-19 or symptoms showing up again two to eight days after recovery, typically lasting about three days. Both President Joe Biden and first lady Jill Bidenhad rebound symptoms after taking Paxlovid for their COVID-19 infections, as did infectious disease expert D...

The data is not conclusive on whether the medication can prevent the miserable symptoms that can linger for months or longer after a bout of COVID-19. But one recent study of veterans, not yet peer reviewed,showed that taking Paxlovid was associated with a reduced risk of symptoms such as blood clots, heart rhythm problems, fatigue, liver and kidne...
Again, there's not enough data to say that Paxlovid makes people shed less virus. But generally, people who are sicker shed more virus, so reducing the severity of illness should cut down on shedding and therefore make people less contagious. Pfizer's data also shows that someone's viral load falls quickly once they start taking Paxlovid, Habtezion...
