How does it work?
Paracetamol is an antipyretic and pain reliever. It changes the way your body perceives pain. It also changes the way your body regulates its temperature. Dextromethorphan suppresses your urge to cough. The third ingredient, phenylephrine, is a nasal decongestant; it reduces the swelling of the blood vessels in your nasal passages.
DayQuil Cold & Flu is a combination product that contains the active ingredients paracetamol, dextromethorphan and phenylephrine. It temporarily treats symptoms of the common cold and flu. These symptoms include:
- To cough
- Stuffy nose
- light pain
- A headache
- Sore throat
DayQuil is intended for use during the day. Unlike NyQuil, it doesn’t contain the active ingredient doxylamine, an antihistamine that can make you sleepy.
What are the forms and dosages?
DayQuil comes in liquid-filled capsules called LiquiCaps. It also comes as a liquid that you drink. The table below shows the recommended dosage for each form by age group. Ask your doctor about the correct dosage for children aged 4 to 5 years, and do not give DayQuil to children younger than four.
DayQuil can cause some undesirable side effects. Most of these side effects do not require medical attention. Instead, they can go away as your body gets used to the drug. You can ask your doctor about minor side effects that are annoying or won’t go away.
