Many people wonder whether or not they can take dayquil at night. The answer is that it depends on the individual and how their body reacts to the medication. It also depends on other factors such as diet, sleep habits and underlying health conditions. Ultimately, it is best to speak with a healthcare professional for personalized advice. In addition to discussing medication options, they may recommend other nonmedicated sleep aids such as calming music, quiet environment and a light dinner.
The main ingredients in Dayquil are acetaminophen (pain reliever), dextromethorphan (cough suppressant) and phenylephrine (wakefulness promoter). If the medication is taken close to bedtime, it can interfere with sleep patterns. This is why it is recommended to use Dayquil during the day rather than at night. A similar over-the-counter medication called NyQuil is specifically formulated for nighttime use and contains ingredients that promote sleep.
While some side effects of DayQuil are minor, other side effects can be more serious and require medical attention. Some of these include dizziness, stomach ache, nausea and nervousness. The medication is also not recommended for those who are pregnant or breastfeeding, or have a weakened immune system.
The acetaminophen in Dayquil can cause liver damage if consumed in excess or over prolonged periods of time. It is also important to avoid taking the medication with alcoholic beverages as it can increase the risk of harming the liver. This is particularly true for those who already have a preexisting condition such as liver disease, kidney disease or diabetes. Lastly, the medication should not be taken with certain medications including monoamine oxidase inhibitors such as isocarboxazid, phenobarbital, phenytoin and tranylcypromine.
