Acetaminophen is a pain reliever and a fever reducer. It is used to treat many conditions, such as headache, muscle aches, arthritis, backache, toothaches, colds, and fevers.

Phenylephrine and phenylpropanolamine are decongestants. They constrict blood vessels (veins and arteries). This reduces the blood flow to certain areas allowing nasal and respiratory (breathing) passages to open up.
