RB, formerly known as Reckitt Benckiser, has shifted its consolidated vitamins, minerals and supplements business, including brands Airborne and MegaRed, to McCann Erickson.
McCann was awarded RB's Mucinex and Delsym business following a global review earlier this year in which RB shifted creative responsibilities for several brands to McCann, Wieden + Kennedy and Droga5.
An RB statement cited the "the excellent work" McCann has already done on Mucinex as a reason for the vitamins, minerals and supplements shift.
Karlin Williams Graybill previously handled the business in the U.S.; Havas Worldwide ran the business overseas. The brands spent nearly $20 million in media during the first six months of this year and almost $47 million in media in 2013, according to Kantar. Representatives for McCann and RB could not immediately be reached.
