As noted by the CDC, part of the reason it is not recommended to take painkillers before being vaccinated is that there was no chance to study the effect that this can have. But other health professionals shared similar warnings about possible problems, including the University of California at Irvine. “Do not pre-medicate”, warn specialists at UC Irvine. “In general, premedication with over-the-counter medications that reduce fever or inflammation, such as acetaminophen (eg, Tylenol) and ibuprofen (eg, Motrin, Advil) before receiving a vaccine, can reduce your ability to act and can decrease your immune response to the vaccine. “
That’s because “these OTC [over-the-counter] drugs work as anti-inflammatory drugs and block a pathway called the cyclooxygenase-2 (cox-2) enzyme, ” Ashley Ellis, PharmD, director of clinical operations at Compwell, said earlier Better life. Your body needs these enzymes to be able to produce many “B lymphocytes, which produce antibodies against COVID, the flu or any pathogen against which the vaccine is trying to protect itself”.
