NyQuil

NyQuil is a brand of over the counter medication which is intended to relieve various symptoms of the common cold. Because all of the medications within the NyQuil imprint contain sedating antihistamines and/or hypnotics and alcohol, they are typically taken at night, just before bedtime. Its daytime counterpart is DayQuil, which does not contain sedating antihistamines and is intended not to induce drowsiness. Both NyQuil and DayQuil are manufactured by Procter & Gamble.

NyQuil is formulated as either liquid or capsules (LiquiCaps). The liquid form was test marketed in 1966 and finally widely introduced in the fall of 1968 (with numerous magazine ads and television commercials), and the capsules were introduced in the late 1980s. The product's slogans have traditionally described the product as "The nighttime, sniffling, sneezing, coughing, aching, best-sleep-you-ever-got-with-a-cold medicine" where the list is slightly tailored to the particular formulation being offered.

There are many theories as to where the name NyQuil originated from, but it is believed that it is derived from the term "Nighttime Tranquility".

Reformulation

Vicks chose to keep its products more easily accessible by reformulating NyQuil Sinus, replacing pseudoephedrine with phenylephrine. Many people were outraged by this change and chose to boycott the product, because studies have shown that phenylephrine is no more effective than a placebo. Due to the protest, Vicks chose to revert to the original formula which became NyQuil D.

NyQuil no longer contains phenylephrine except for the sinus LiquiCaps variety.
