NyQuil is an over-the-counter cold, flu, cough and sinus medication manufactured by Vicks, a division of Procter & Gamble. NyQuil is typically taken at night, as drowsiness is a common side effect. Originally available in liquid form, it's also produced in LiquiCap form. DayQuil is a similar product produced by Vicks for use during the day, marketed as providing many of the same benefits as NyQuil without inducing drowsiness.
