Can You Take Dayquil At Night? Everything You Need To Know

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

These three ingredients work together to alleviate cold symptoms such as headache, sore throat, cough, fever, and minor aches and pains.

DayQuil, as the name implies, is designed for use during the day. NyQuil, which has similar properties to DayQuil, must be taken at night.

NyQuil should only be taken at night due to the presence of drowsy and sleep-inducing ingredients such as diphenhydramine (Benadryl) and others. This is why they’re called NyQuils.

How does Dayquil work?

Dayquil Cold and Flu is a combination of three medications that help alleviate the symptoms of a cold or the flu.

  • Acetaminophen, which is an analgesic. It works by preventing the production of certain molecules in the body that cause fever and pain, providing relief.
  • Dextromethorphan, a cough suppressant. It acts in the brain to reduce the urge to cough, which can help alleviate coughing associated with a cold or the flu.
  • Phenylephrine, a decongestant. It helps clear your sinuses, reducing sinus pressure and relieving a stuffy nose.

What are the Uses of Dayquil?

Dayquil is a medication used to treat a variety of common conditions, including:

  • Headache
  • Aches
  • Fever
  • Cough
  • Sinus pressure
  • Sore throat
  • Nasal congestion
  • Sinus congestion

Can you take Dayquil at night?

Yes, you can take Dayquil at night without worrying about it causing drowsiness. It doesn’t contain any ingredients that will keep you awake.

It’s important to follow the recommended dosage and not exceed more than 4 doses within a 24-hour period.

Whether you take it during the day or at night, the usual guideline is to take one pill every 4 hours.

Remember to always read and follow the instructions on the packaging and consult with a healthcare professional if you have any concerns or questions.

Does DayQuil stop you from sleeping?

No, DayQuil does not contain a sleep stimulant. Its purpose is to alleviate symptoms of the common cold and flu, such as fever, sore throat, headache, minor aches and pains, and cough. The active ingredients in DayQuil are Acetaminophen (which relieves pain and reduces fever), Dextromethorphan (a cough suppressant), and phenylephrine hydrochloride (a nasal decongestant).

If your cold or flu symptoms are making it difficult for you to sleep at night, it is suggested to take DayQuil earlier in the day.

What will happen if I take Dayquil at night?

Taking Dayquil at night will not make you feel sleepy because it does not contain any stimulants. However, NyQuil, which is a different medication, contains a sedative ingredient that can make you feel sleepy after taking it.

It’s important to note that Dayquil is designed to relieve cold and flu symptoms, but it does not specifically help with falling asleep. If you typically have difficulties falling asleep due to your symptoms, Dayquil can help alleviate those symptoms, which may in turn make it easier for you to sleep. Once your symptoms have subsided, you should be able to fall asleep naturally on your own.

What Happens When You Use DayQuil in the Morning?

When you take DayQuil first thing in the morning, it helps to relieve your cold and flu symptoms, allowing you to feel more at ease and get on with your day.

If taken as directed in terms of dosage and intake, DayQuil will treat the symptoms. Your cold or flu symptoms will disappear after taking DayQuil as directed during the day.

However, it is always important to carefully read the label and consult with your doctor if you have any questions.

Can I take DayQuil on an empty stomach?

DayQuil can be taken on an empty stomach. There are no restrictions on whether it should be taken with or without food. If you experience stomach discomfort after taking DayQuil on an empty stomach, try taking it with food or a light snack to see if it relieves any potential irritation. It’s always a good idea to follow the instructions on the package or seek specific advice from a healthcare professional.

Can I take DayQuil and ibuprofen?

DayQuil and ibuprofen are generally safe to take together, but it’s important to stick to the recommended dosages and consult with a healthcare professional if you have any concerns or specific medical conditions. Because DayQuil already contains acetaminophen, you should avoid taking it with other acetaminophen-containing medications to avoid exceeding the recommended dose. Ibuprofen, on the other hand, is a different type of pain reliever that can be used in conjunction with DayQuil if necessary, as long as you follow the dosage guidelines for both medications.


Finally, if you need relief from your symptoms, you can take Dayquil at night. However, it is always best to read the label and consult your doctor before taking any medication. Taking Dayquil at night may assist you in getting the rest you require to feel better in the morning.
