Does DayQuil Keep You Awake? Tips For Sleeping After Taking DayQuil

DayQuil is a medication that relieves flu and cold symptoms. But what if you take it right before bed? Does DayQuil keep you awake? 

The short answer is no. DayQuil does not contain the drowsiness-inducing substances like antihistamines or caffeine present in NyQuil.

The rest of this post discusses the effects of DayQuil on sleeping. We’ll also give you some tips on how to sleep better when you’re suffering from a cold, flu, sore throat, or nasal congestion. Let’s follow our guide! 

What Is DayQuil?

Acetaminophen, phenylephrine, and dextromethorphan are the active ingredients of DQuil. These medications each have a different role in boosting efficacy. 


Acetaminophen is a painkiller that also reduces fevers. This medicine, often known as paracetamol, influences how the body feels pain when consumed. 

This ingredient also cools your body by way of the brain’s heat-regulating area.


Phenylephrine hydrochloride is the nasal decongestant that reduces ear and nasal swelling, making breathing easier. 

It works by stimulating the outflow of the sinus canals by stimulating the alpha-1 adrenoceptors in the nasal mucosa.


The cough suppressant ingredient in dextromethorphan can deal with cold and flu symptoms. It passes the blood-brain barrier of your body, blocking the sigma opioid receptors to stop coughing. 

NyQuil and DayQuil include this cough suppressant, which has numerous therapeutic benefits.

When taken together, each of these drugs works to combat the adverse symptoms of the common cold and flu

Cough, fever, sore throat, weariness, headaches, and nasal congestion are adverse effects.

Does Dayquil Keep You Awake?

When you take this medicine before going to bed, it will not make you stay awake. The active components of the treatment do not include any stimulants.

The medicine’s active components are all non-drowsy, which means your body can retain its average energy level. In addition, DQuil is caffeine-free.

It’s worth noting that DQuil doesn’t include any sleep aids. It will also not influence how easy or difficult it is to fall asleep at night.

Difference Between DayQuill Vs. NyQuil

NyQuil and DayQuil are available in both liquid and tablet form. They help relieve typical cold or flu symptoms. One significant difference between them is that NyQuil is a sleep aid, but DQuil isn’t.

NyQuil includes an antihistamine, and DQuil involves a nasal decongestant. NyQuil’s antihistamine can make you sleepy, which can help you fall asleep easier even if you’re sick with the common cold and seasonal flu.

Ultimate Guides To DayQuil 

The following is a brief description of how DayQuil works in relation to sleep.

Recommended dose 

The suggested DQuil dose depends on several factors, including the user’s age, the health issue being treated, and the medication’s type.

Adults and children over the age of 12 can take two capsules every four hours. The patient must not use more than four tablets in a 24-hour cycle.

If DayQuil comes in liquid form, it is advisable to drink about 30 mL per 4 hours as required. However, you shouldn’t consume more than four doses in 24 hours.


It is crucial to remember that children under six years old must not use this medication unless their physician recommends it. 

Also, avoid overusing or misusing the DQuil dextromethorphan. Dextromethorphan is a widely mishandled drug that, in excessive quantities, can induce hallucinations.

As a result, it’s best to closely follow the DQuil appropriate dose instructions and prevent the potentially dangerous abuse of DayQuil or its contents.

Side effects

DayQuil is generally safe to consume when taken as prescribed, although it may cause some minor and major adverse effects.

Most of the side effects are self-resolving and do not need medical treatment.

If you have a major or minor adverse effect for an extended time, consult your health care physician immediately. 

  • Minor effects

Lightheadedness, nausea, dizziness, upset stomach, sleepiness, vomiting, and anxiety are the most frequent and milder side effects.

  • Serious effects

An allergic reaction is a severe DayQuil side effect requiring immediate medical treatment.

Breathlessness, swelling of the tongue, skin rash, trouble breathing, red and blistered skin, and edema of the feet, legs, and hands are all indications of an adverse drug reaction.

If you encounter any of the symptoms mentioned above while using DQuil, you should seek help immediately.

Be cautious of any side effects

Interaction with other medications

DayQuil’s active ingredients can interact with other drugs or foods.

As a result, patients should use DayQuil with caution. Drug-drug interactions, as well as drug-food interactions, can be frequently synergistic or additive. 

When taken together, they may end up doing more harm than when used separately.

Suppose you’re already taking medications like warfarin, phenytoin, isoniazid, carbamazepine, phenobarbital, or phenothiazines. 

In that case, you should be aware that the acetaminophen in DayQuil may react with them and produce adverse side effects.

If you’re taking MAOIs like isocarboxazid or phenelzine, you should take caution. DayQuil’s dextromethorphan and phenylephrine may interact negatively with MAOIs.

Please remember that even if you have stopped using the medications indicated above, there is always a risk that potential interactions will happen until they are no longer in your body.

How To Sleep Better After Taking DayQuil? 

DayQuil neither induces nor prevents sleep. If you’re having trouble falling asleep, there are a few tips that might help.

Use lukewarm water to gargle

It would be best to gargle with lukewarm water before bedtime. This tip will help relieve a sore throat.

You can mix some salt with lukewarm water to make this solution. It provides immediate comfort and is a simple home therapy.

Gargling can also help prevent bacterial diseases like strep throat from forming and developing.

Adjust your sleeping posture

While sleeping, consider raising your head with a few pillows. By establishing a slight incline to clear your sinuses, this posture can help you breathe properly while sleeping.

The fluid and mucus that has accumulated in your upper respiratory tract will slowly clear out, allowing you to fall asleep more quickly.

You can pile a few pillows beneath your head or, if possible, raise the height of your mattress.

Avoid putting too many cushions. They can add pressure on your neck, causing neck pain, muscle aches, and discomfort. Two pillows should be enough to clear the mucus from your sinuses.

An adjustable bed offers a safe option to raise your head while maintaining the proper posture.

Install a humidifier in your room

When you have flu, cold, or a clogged nose, a humidifier in your room may provide some comfort as you’re sleeping.

The humidifier moistens the air and helps breathe through a runny nose significantly easier. You must, though, ensure that the humidifier is always clean and clear of bacteria.

It is also strongly advisable to sanitize the humidifier regularly. Bacteria and germs may quickly build up and expand in this equipment.

Make your room noise-free

One of the most common issues that keep you awake is a loud setting. If you’ve had problems sleeping due to loud noises, lower the volume in your room.

During bedtime, avoid loud noises like TVs, radios, or computers. If you share a bed, let your partner know you’re going to sleep.

He or she should avoid making disturbing noises by talking loudly on the phone.

However, there are cases when you cannot avoid being subjected to noise. Noise-canceling headphones appear pretty beneficial in this situation. 

They can shut background sounds, allowing for a pleasant night’s sleep

Adjust your room thermostat

Another effective method to get a decent night’s sleep after taking DayQuil is to control the temperature in your room.

Cool environments link to sleep in our human brain. As a result, lowering the temperature in your room can help you get a better night’s sleep.

Low temperatures can stimulate the production of hormones like melatonin by delivering the necessary signals to your brain. It starts and maintains the sleeping process going smoothly.

Other methods to lower the room temperature include leaving the door open and turning the fan on. 

A cooler setting also enhances the body’s capacity to control its internal temperature. This strategy can shorten the time required to fall asleep and improve your sleep quality.

Develop a sleeping habit

Routines have a beneficial impact on your body. It will be simpler to fall asleep if you go to sleep and wake up at the same time every day. 

You will have no difficulty tossing and rolling in your bed, whether you’ve used DayQuil or not.

To obtain the most excellent results, note how many sleeping hours your body requires and set your timetable accordingly.

Avoid distractions

One of the most common reasons you stay awake longer than you should is distractions before your bedtime. Social media and smartphones can steal you of precious rest.

Rather than allowing your body to relax, you may spend many hours on YouTube Or Facebook before going to bed. 

It’s no surprise that specialists advise shutting all electronic gadgets one hour before your bedtime. You’ll be surprised at how much better your sleeping will be.

Don’t be too full or too hungry.

It’s not a good idea to be hungry and go to bed after taking DayQuil. The medication may not work well if you leave your stomach empty. 

However, it would help if you didn’t stuff your stomach with hundreds of calories before bed.

If you don’t wait three hours after eating a big meal, you may get digestive problems, resulting in sleep disruptions. 

Even the digestive strain might cause increased wakefulness before bedtime when you should sleep for some more hours.

In addition, overeating before bed might cause nasty side effects that disrupt your sleeping.

If you must dine late at night, wait for at least two to three hours before going to bed. This duration should give you enough time to digest your food.

No caffeine

Caffeine’s sleep-inhibiting characteristics are familiar to all of us. Late-night espresso runs aren’t good for your bedtime. 

Dehydration is another side effect of coffee. You may have to keep drinking water the whole night.

Standing up to drink water increases your chances of using the toilet more frequently, which can cause severe sleeplessness.

If you must have a cup of coffee, do it earlier than midday. The effects should have gone by bedtime.

Light exercises

The cold and flu symptoms can harm the body, causing fever, headaches, and nausea. Although an intense workout may be unnecessary, nothing should prevent you from engaging in light exercises. 

A 15-minute stroll every evening, particularly after dinner, can boost your sleeping quality.
