WARNING

Dayquil is an over-the-counter medication commonly used to relieve symptoms of colds and flu, such as congestion, cough, and fever. While generally safe when used as directed, there are some risks associated with taking Dayquil:

• Allergic Reactions: Some individuals may be allergic to ingredients in Dayquil, such as pseudoephedrine or acetaminophen. Allergic reactions can range from mild skin rashes to severe anaphylaxis.

Taking more than the recommended dose of Dayquil or using it along with other medications that contain acetaminophen can increase the risk of overdose.

It’s essential to read and follow the instructions on the Dayquil packaging carefully, and if you have any concerns or questions about taking Dayquil, it’s best to consult with a healthcare professional.

Why is this medication prescribed?

Dayquil is not prescribed by healthcare providers but is instead available over-the-counter for self-use. It’s commonly used to relieve symptoms associated with the common cold and flu, such as nasal congestion, cough, sore throat, headache, minor aches, and fever.

How should this medicine be used?

As for how Dayquil should be used:
