🩺 Clinical
Acetaminophen is used to relieve mild to moderate pain and to reduce fever. Acetaminophen is in a class of medications called analgesics (pain relievers) and antipyretics (fever reducers). It works by changing the way the body senses pain and by cooling the body.
Read the full MedlinePlus article ↗This is an over-the-counter liquid cold and flu product taken by mouth. It contains four active ingredients that work together for symptom relief: acetaminophen is typically used to reduce fever and relieve aches and pain, dextromethorphan is a cough suppressant, guaifenesin is an expectorant that helps thin mucus, and phenylephrine is a decongestant meant to ease nasal congestion. The product is sold as an OTC monograph drug, meaning it follows FDA's established rules for this category rather than undergoing individual product review.
