What is Dayquil, and why is it used?


DayQuil is an over-the-counter medication that combines the active ingredients of acetaminophen, dextromethorphan, and phenylephrine.

These three components help to relieve cold symptoms such as headache, sore throat, cough, fever, and minor aches and pains.

Dayquil works differently than other medications because it contains two components that work as a decongestant (phenylephrine) and one that acts as an analgesic/fever reducer (acetaminophen).

DayQuil can be taken every 4 hours but no more than four times in one day. You should not take it for more than five days without asking your doctor first.

Rigidly following the instructions on the packaging and heeding dosage directions are essential when taking DayQuil. Overdosing this medication may lead to several adverse side effects, including dizziness, nausea, a racing heart rate, or worse.

When should you take Dayquil?

Take DayQuil every four to six hours, as indicated on the packaging. You can take it at night, but sleeping several hours before bedtime is best without possible side effects or lingering symptoms.

It's important to note that if you are taking DayQuil and not feeling relief after four doses (16 hours), you should seek medical attention and adjust your course of treatment accordingly.
