Experts warn that despite the first antiviral pills for COVID-19 promising protection for those at risk of severe disease, Pfizer's or Merck's new medications may not be safe for everyone, NBC News reported over the weekend.
One of the two drugs in Pfizer's Paxlovid antiviral cocktail could cause severe or life-threatening interactions with commonly used medications, including statins, blood thinners and some antidepressants, and the FDA does not recommend Paxlovid for those with severe kidney or liver disease.
In addition, due to concerns about the potential side effects of Merck's molnupiravir, the FDA has restricted its use to adults and only in cases in which other treatments are inaccessible or are not ''clinically appropriate.''
The main concern is that when Paxlovid is paired with other medications that are also metabolized by the CYP3A enzyme, the ritonavir component may boost the co-administered drugs to toxic levels.
