It’s getting more durable to keep away from COVID-19, because of the dominance of BA.5 within the U.S. and the rising variety of different Omicron subvariants. Fortuitously, Pfizer’s antiviral remedy Paxlovid can reduce sickness from the illness.
But it surely’s not meant for everybody. Solely those that are at elevated threat for extreme illness from COVID-19 qualify for the drug, together with individuals over age 12 who’ve weakened immune methods or different health conditions that enhance threat of great results of COVID-19—like bronchial asthma, most cancers, liver illness, lung illness, coronary heart illness, and weight problems. Paxlovid additionally comes with an inventory of potential hostile reactions with widespread medication, similar to cholesterol-lowering statins.
As a result of the drug shouldn’t be accredited by the U.S. Meals and Drug Administration, however allowed beneath an emergency use authorization, medical doctors typically can’t prescribe it outdoors of the authorization standards. But that’s not stopping individuals of all ages and threat profiles from asking for Paxlovid, which went from hard-to-find to rather more accessible in only a few months. From December 2021, when Paxlovid was licensed, to June 2022, prescriptions for the drug have jumped from 2,500 to almost 1 million within the U.S., in accordance with knowledge supplied to TIME by health-data firm Iqvia.
Right here’s what prescribers say about who ought to get Paxlovid at this level within the pandemic.
Individuals at greater threat profit extra
Studies carried out by Pfizer earlier than Paxlovid was licensed have discovered that the drug reduces the danger of hospitalization and demise by as much as 89% amongst unvaccinated individuals at excessive threat for unhealthy COVID-19 outcomes. That efficacy has turn out to be much less spectacular as vaccination has elevated: the corporate’s newest knowledge present that Paxlovid is about 57% efficient at reaching these outcomes in vaccinated individuals at decrease threat of extreme sickness, similar to those that have a minimum of one of many risk factors that increase the danger of great COVID-19 sickness.
Different data that Pfizer launched in June confirmed that the drug doesn’t considerably cut back the variety of signs amongst individuals of any vaccination standing who’re at reasonable threat of extreme illness, in comparison with these not taking it. “That knowledge modified how I see the medicine, which was as soon as hailed as a sport changer,” says Dr. Anand Viswanathan, assistant professor of medication at NYU Langone Well being.
Even after the drug was licensed by the U.S. Meals and Drug Administration (FDA) in December 2021, provides had been scarce, however the Biden Administration raised consciousness and entry to Paxlovid in March by asserting the Take a look at to Deal with program, which allowed individuals to get examined at locations like pharmacies and obtain a prescription on the spot in the event that they had been constructive. Provide of the drug elevated by the spring, and it went from being under-prescribed (with the intention to reserve restricted provides for individuals at highest threat) to standard amongst medical doctors and sufferers. On July 7, the FDA additional expanded access by permitting state-licensed pharmacists to write down prescriptions for anybody over age 12.
With improved entry, some consultants consider the drug might now be overprescribed. Paxlovid remains to be one in every of just a few COVID-19 antiviral therapies licensed by the FDA (others embrace a capsule known as molnupiravir and remdesivir, an IV remedy) so persons are nonetheless asking for it. “There’s in all probability some overprescribing or prescribing in low-risk individuals,” says Dr. Amesh Adalja, senior scholar on the Johns Hopkins Middle for Well being Safety and an infectious illness doctor.
Regardless of the drug’s elevated recognition, for people who find themselves in any other case wholesome and never at excessive threat of getting severely sick, there are restricted knowledge supporting the advantages of taking antivirals like Paxlovid. “For the typical wholesome individual—even a 55 yr previous with no main medical issues—they may not profit and simply complain of the unhealthy style of their mouth,” which is a standard aspect impact of Paxlovid, says Adalja. “You must return to the first objective of prescribing Paxlovid: to forestall extreme illness, hospitalization, and demise.”
Prescribing by age
Even for individuals with signs who don’t produce other well being circumstances, Adalja typically doesn’t prescribe Paxlovid except they’re ages 65 or older. That’s a standard yardstick that medical doctors are beginning to use. However there are not any onerous and quick guidelines, even relating to age. Dr. William Durkin, an emergency doctor at Alvarado Medical Middle in San Diego, lately determined to not prescribe Paxlovid to an older affected person who was in any other case wholesome and didn’t have any signs.
For such sufferers who don’t have signs once they check constructive, medical doctors might write a prescription proactively and inform them to succeed in out in the event that they do develop signs in a day or so. As a result of Paxlovid is simplest if taken inside 5 days of signs showing, having the prescription prepared may make sure that individuals reap the benefits of the quick window through which the drug works.
The way forward for Paxlovid
Used correctly, an antiviral like Paxlovid will help to sluggish transmission because the extremely contagious Omicron variants proceed to unfold. “Now we have been working diligently with clinicians, group organizations, and most people to make individuals conscious that these medicines can be found and the way essential it’s to know your threat elements for extreme COVID-19 illness,” says Dr. Mary Mercer, affiliate professor of emergency medication on the College of California San Francisco and Zuckerberg San Francisco Common Hospital and Trauma Middle. By limiting the quantity of extreme illness in communities, the drug is one other option to maintain the virus beneath management.
Ought to a brand new variant seem that’s even higher at evading the safety afforded by vaccines, and which causes extra critical illness even among the many vaccinated, then “Paxlovid might discover itself again within the position of sport changer,” says Viswanathan.
