DayQuil Important Info And Tips




DayQuil Cold & flu may be the best option for you if you need a single product that treats both the common cold and flu symptoms. You will learn how it works, what the dosages are, and what to watch out for a while you use it.


DayQuil Cold & Flu is a combination of acetaminophen and dextromethorphan. This temporarily relieves symptoms of the common cold or flu. These symptoms are:

  • Fièvre
  • Cough
  • Nasal congestion
  • Minor aches and discomforts
  • Kopfschmerz
  • Sore throat

DayQuil can be used during the day. DayQuil is not like NyQuil. It doesn’t contain the active ingredient, doxylamine. This antihistamine can cause you to feel dizzy.

What is the secret to it?

Acetaminophen can be used as a fever reliever and pain killer. Acetaminophen works by altering the way your body perceives pain. It can also alter the way your body regulates temperature. Dextromethorphan reduces the urge to cough. Phenylephrine is the third ingredient and acts as a nasal decongestant. It decreases swelling in the nasal passages.

What are the dosages and forms?

DayQuil is available in liquid-filled capsules known as LiquiCaps. You can also find it in the liquid you drink. Below is a table that lists the recommended dosages for each product by age group. Ask your doctor about the recommended dosage for children aged 4-5 years. DayQuil should not be given to children younger than 4 years.
