What is nyquil and what does it do?

Nyquil is a liquid medication that you can take to relieve the symptoms of a cold or flu. It’s usually a combination of different things, such as acetaminophen, dextromethorphan, and other ingredients. Acetaminophen is a mild painkiller, and dextromethorphan is a cough suppressant.

Almost all nyquil (or its various knock-offs) contain antihistamines. These are used to treat allergies and some cold-like symptoms. They also help you fall asleep by relaxing your muscles, including your blood vessels.

If you don’t have allergies and you catch a cold, you may not want to take an antihistamine. They can make you drowsy, which is great if you have a cold and want to fall asleep.
