🩺 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 ↗Nighttime Severe Cold and Flu is an oral liquid OTC product containing four active ingredients that work together to address multiple cold and flu symptoms. Acetaminophen is commonly used to reduce fever and relieve pain, while dextromethorphan is typically used as a cough suppressant. Phenylephrine functions as a decongestant to help relieve nasal congestion. Doxylamine succinate is an antihistamine commonly used to promote drowsiness and help with sleep during nighttime illness. This is an OTC monograph product, meaning it is marketed under FDA's established guidelines for this category of cold and flu remedies.
