Avoid Painkillers Before and After Covid Vaccine, Experts Say
Mild fever or other symptoms means the vaccine is working. Don’t mess with that.
Experts say that people should avoid painkillers before and after getting a Covid-19 vaccine, to give it the best chance of doing what it’s supposed to do: stimulate your immune system. Mild symptoms like fever, chills, headache, and tiredness indicate the vaccine is tricking your cells into learning how to fend off the coronavirus.
“These symptoms mean your immune system is revving up and the vaccine is working,” says Rochelle Walensky, MD, director of the U.S. Centers for Disease Control and Prevention.
“Don’t use them beforehand. Try very hard not to.”
“This builds immunological memory,” says Michael Mina, MD, an assistant professor of epidemiology at Harvard T.H. Chan School of Public Health.
Painkillers are known to interfere with effectiveness of flu shots. The possibility has not been studied with Covid vaccines, but Mina and other experts say it’s possible, so they advise skipping painkillers if you can bear it. If you’re already routinely taking them for a health condition, you should not stop without talking to your doctor.
