What happens if you take NyQuil every night?

Taking NyQuil every night is not recommended. NyQuil contains acetaminophen and other ingredients like alcohol, which can cause liver damage if taken too frequently. Taking NyQuil every night can also lead to tolerance and dependence, and can make it harder for you to sleep without it in the future. If you are having trouble sleeping, it is best to talk to your doctor about other options.

How many nights can you take NyQuil in a row?

NyQuil should only be taken for a maximum of 7 consecutive nights. If you need to take NyQuil for more than 7 nights, please speak to your doctor or pharmacist to discuss alternative treatments.
