The Food and Drug Administration first issued an emergency use authorization for Paxlovid in December.

Paxlovid is an antiviral treatment supposed to regard delicate to reasonable COVID-19, Dr. Michelle Hormozian, a scientific coordinator and pharmacist with the University of Southern California School of Pharmacy, informed McClatchy News. It is composed of 2 other oral antivirals: nirmatrelvir and ritonavir.

“One of the medications [nirmatrelvir], it’s actually a COVID protease inhibitor, and what that means is it basically prevents viral replication of COVID,” Hormozian mentioned

The 2d drugs, ritonavir, works to dam the metabolism of the primary drug in order that the frame can care for enough ranges of nirmatrelvir to paintings correctly, Hormozian mentioned.

COVID-19 sure sufferers who’re prescribed Paxlovid will take it two times an afternoon for 5 days, in keeping with Hormozian.

Patients, relying on their scientific historical past and present medicines, will take one or two nirmatrelvir drugs and one ritonavir tablet, Vijayan mentioned.

Some possible negative effects of the drug would possibly come with an altered sense of style, disillusioned abdomen or diarrhea, larger blood drive or muscle aches, in keeping with Hormozian.

“So, it’s not used for prevention. It’s not used for patients who might have been exposed but are not testing positive or those who are asymptomatic,” Hormozian mentioned.

The drug is prescribed to those that are at upper possibility of progressing into extra serious COVID-19, Hormozian mentioned.
