NEW YORK — Another nighttime remedy that historically has performed well is Procter & Gamble’s combo pack of Vicks Nyquil and Vicks Dayquil. Sales of the combo liquids were up 94.2% to $39 million, and sales of its tablet combo pack were up 16% to $45.7 million. Vicks combination packs may soon get another lift from the Sochi 2014 Olympic Winter Games in Russia, of which P&G is one of the corporate sponsors. The Vicks Nyquil/Dayquil brands tapped U.S. Alpine skier Ted Ligety as a spokesman this season.
