The most common drug in America, acetaminophen, is an external analgesic that works as a pain reliever and fever reducer. Over-the-counter medicines such as Tylenol, DayQuil, Theraflu and Vicks contain acetaminophen, as well as prescription drugs including Vicodin and Oxycodone. Acetaminophen is often the drug the pediatrician’s office advises for feverish, inconsolable infants and children when they experience adverse effects from vaccines. Yet studies have found the popular drug plays a role in oxidative stress and inflammation from birth to early childhood in the induction of autism, ADHD, and asthma. Many studies show the go-to drug, once thought to be benign, is actually a neurotoxin, and places pregnant women, infants, and children at risk for serious adverse side-effects.
