DayQuil Severe Cold and Flu works by targeting multiple symptoms at once. Its active ingredients work together to provide relief in several ways:

1. Acetaminophen (Pain Reliever/Fever Reducer):
   • Reduces fever and relieves minor aches and pains, such as headaches, sore throat, and body aches.
2. Dextromethorphan (Cough Suppressant):
   • Helps control coughing by acting on the part of the brain that triggers the cough reflex.
3. Phenylephrine (Nasal Decongestant):
   • Shrinks swollen blood vessels in the nasal passages, making it easier to breathe and relieving congestion.
4. Guaifenesin (Expectorant):
   • Helps thin and loosen mucus in the airways, making it easier to cough up and clear your chest.

By combining these ingredients, DayQuil Severe Cold and Flu provides comprehensive relief for the most bothersome cold and flu symptoms.
