Nyquil is a commonly used night-time flu and cold treatment that’s available over the counter.
As well as relieving the typical cold and flu symptoms, it also acts as a sedative and you’re meant to take it before you go to sleep at night (the equivalent medication for use during the day is called Dayquil).
Because of its sedative properties, Nyquil is also often used purely as a sleep aid. And as it causes marked drowsiness, a question you need to know the answer to is how long does it take for Nyquil to kick in?
You need to know the answer to this so that you can properly plan when to take it.
You don’t want to place yourself in the position of having taken Nyquil and started to feel drowsy when you need to be alert, for example if you need to drive.
How long does it take for Nyquil to kick in?
So, just how long does Nyquil take to work?
The short answer is not long at all. Whichever form of it they take (it’s available in liquid and tablet form), for most people Nyquil will start to kick in after about 10-15 minutes and they will be asleep within half an hour. Some people may find it takes a little longer to kick in – maybe between 45 minutes to an hour before they fall asleep.
How long does Nyquil make you sleep?
If you’re going to take Nyquil, it’s important that you also know how long it will make you sleep. Typically the effects of Nyquil will last for up to 8 hours.
This time will depend on the individual and their reaction to the sedative ingredients of Nyquil though. So it’s advisable you practice care when you first take Nyquil and see how you personally react to it and how long it makes you sleep.
