Taking the antiviral therapy Paxlovid can cut back an individual’s possibilities of getting critically unwell from COVID-19. However whereas seniors are likely to get spectacular safety from the drugs, youthful folks derive little profit, finds new analysis.
In a examine printed Aug. 24 within the New England Journal of Drugs, researchers in Israel present priceless real-world knowledge on how efficient the drugs are in opposition to Omicron. The researchers studied knowledge from 109,000 sufferers at a big well being care group—practically all of whom had been vaccinated, had been beforehand contaminated, or each—and tracked their hospitalization and loss of life charges by age. Almost 4,000 folks within the examine, which was performed from January to March 2022, took Paxlovid.
Individuals who have been 65 or older had a 73% decrease likelihood of being hospitalized for COVID-19 and a few 79% decrease likelihood of dying of the illness, in comparison with folks in the identical age group who didn’t take Paxlovid. However folks ages 40 to 64 skilled no statistically vital drop within the threat of hospitalization or loss of life.
Primarily based on the findings, the authors conclude that “no proof of profit was present in youthful adults.”
To qualify for Paxlovid, sufferers have to be at elevated threat of creating critical sickness from COVID-19. Danger elements embrace older age, in addition to circumstances akin to weight problems, hypertension, diabetes, and a historical past of coronary heart and kidney failure. However the Israeli knowledge recommend that age could also be an much more necessary consideration for evaluating who ought to take it.
Whereas the advantages are clear for seniors, the findings throw into query whether or not taking the drug is value it for folks beneath 65. It comes with potential unwanted effects, together with diarrhea, muscle aches, a rise in blood stress, and an aftertaste so dangerous that it will probably quickly have an effect on some folks’s skill to eat. Paxlovid additionally interacts with frequent medicines, akin to cholesterol-lowering statins, so some medical doctors advise sufferers to cease or cut back these medicines through the five-day Paxlovid course. And there are growing stories that folks taking Paxlovid are prone to expertise a rebound an infection, or having the virus re-emerge after they cease taking the drugs.
One caveat of the examine is that the researchers didn’t break down knowledge on youthful folks with most cancers and different extreme immunocompromising circumstances, who could also be extra doubtless than different younger folks to profit from Paxlovid—maybe to a larger extent than the info confirmed. As extra folks take the medicines, medical doctors can have a greater understanding of who will profit most, and for whom the advantages outweigh the dangers.
