A member asked:

Can taking nyquil before you get sick, be harmful? i just need to know if it is harmful

A doctor has provided 1 answer

Nyquil : Nyquil is safe when used as directed for short-term use. However prolonged use over time can cause serious health problems. It is important to note that there are some ingredients in nyquil that can have long-term effects on the body, mainly addiction. To be safe only use this product as needed for cold or flu symptoms.
