Vicks DayQuil is a medicine designed to help relieve many symptoms of a cold. It is available in liquid and “LiquiCap” (capsule) form. DayQuil’s nighttime counterpart is NyQuil, which contains an antihistamine. This antihistamine is a sedative, and may cause NyQuil users to develop a marked drowsiness. Because DayQuil lacks this antihistamine, it doesn’t cause the drowsiness, and thus is suitable for use in the daytime. DayQuil was introduced in 1974 under the name “DayCare.”
