The good news is that most of these side effects are not serious and will go away after a few days. However, there are some people who suffer from the common cold so badly that it makes their lives miserable. Dayquil is an over-the-counter medication that can help reduce the severity of your cold significantly by reducing nasal congestion and nasal discharge.

How does Dayquil work?

Dayquil is a combination of three active ingredients that work together to treat the symptoms of a common cold. The acetaminophen in Dayquil relieves minor aches and pains associated with cold. It also helps reduce fever and acts as an anti-inflammatory.

The cough suppressant in Dayquil helps reduce coughing by weakening the cough reflex. The antihistamine in Dayquil helps reduce nasal discharge by blocking the action of histamine in the body. The decongestant in Dayquil helps reduce stuffy nose by narrowing the blood vessels in the nasal passages. These three ingredients occur in these ratios in every bottle of Dayquil.

Why you should use Dayquil only when you have to?

Dayquil is not a magic pill that can cure your common cold instantly. It is important to note that it may take up to two days for the full effects of Dayquil to be noticeable. In addition to that, the cold symptoms may go away after a few days regardless of whether you take the medication or not.

Taking Dayquil when you don’t need it may cause some unwanted side effects, including drowsiness, dry mouth, dizziness, and nausea. These side effects are rare, but it is important to note that taking Dayquil with other medication may cause some serious complications.

If you have high blood pressure, you should avoid taking Dayquil. Also, if you are on certain antidepressants and anticonvulsants, Dayquil may interact with them and cause some serious side effects. You should talk to your doctor before taking Dayquil if you have any of the above issues.

However, there are other studies that show that Dayquil is as effective as other common cold medications.

While Dayquil does have fewer side effects than other medications, it is not a placebo. While it is not clear why Dayquil has these side effects, it is important to note that these side effects are rare. Most of the side effects of Dayquil can be managed easily by making some simple adjustments. You should talk to your doctor before taking Dayquil if you have any of the above issues.

How Long Does Dayquil Stay In Your System?

The effects of Dayquil usually wear off within 6-8 hours. However, some of the ingredients in Dayquil may stay in your system for a longer time. Acetaminophen is the main ingredient in Dayquil that stays in your system for a longer time.

The amount of time acetaminophen stays in your system will depend on a number of factors, including the dosage of Dayquil you take and your age.
