McNeil Consumer Healthcare recently parlayed its Tylenol brand franchise into external analgesics to quite a bit of success. For the four weeks ended Dec. 26, 2010, Precise “from the makers of Tylenol” became the No. 3 best-selling heat patch, with $1.9 million in sales across food, drug and mass (excluding Walmart), according to SymphonyIRI Group. And its pain-relieving cream similarly broke in among the top-selling brands — No. 9 with $1.3 million in sales for the four-week period.
