It should in theory be more variant proof, and Pfizer has said preliminary lab studies have backed up that hypothesis.</p><p>Paxlovid is a combination of a new molecule, nirmatrelvir, and HIV antiviral ritonavir, that are taken as separate tablets.</p><p>Nirmatrelvir blocks the action of an enzyme the virus needs to replicate, while ritonavir slows down nirmatrelvir&#x27;s breakdown so it remains in the body for longer and at higher levels.</p><p>Possible side effects include impaired sense of taste, diarrhea, high blood pressure and muscle aches, the FDA said.</p><p>There are also potential harmful interactions for people using other drugs, and using Paxlovid in people with uncontrolled or undiagnosed HIV-1 infection may lead to HIV-1 drug resistance, the agency added.</p><p>Authorization is still awaited for another COVID pill, developed by Merck, which is also taken over five days and has been shown to reduce hospitalizations and deaths by 30 percent among high-risk people.</p><p>Independent experts voted in favor of that treatment by a narrow margin, but expressed concerns surrounding its safety, such as potential harm to fetuses and possible damage to DNA.</p><p>The two treatments work in different ways inside the body, and Pfizer&#x27;s pill is not thought to carry the same level of concerns. Merck&#x27;s treatment has been greenlit by Britain and Denmark.</p>

The approval of the COVID pill for high-risk people aged 12 and over is a key moment in the pandemic that will allow millions to access the treatment.
