Dixon has replaced Mark Watkins and now oversees comms across Europe for products such as painkiller Panadol, smoking cessation brand NiQuitin CQ, and drinks such as Ribena and Lucozade.
She will lead ongoing campaigns to encourage people to visit a pharmacist ahead of a GP for minor ailments treatable by over-the-counter products.
Other pan-European initiatives include 'public education' to promote NiQuitin CQ's ability to help people stop smoking.
Dixon's promotion leaves GSK on the hunt for a consumer health comms director for the UK. Recruitment is already under way for the position.
GSK retains Cohn & Wolfe and Jackie Cooper PR as its 'preferred' agencies for its UK consumer health business. It also uses Blue Rubicon for corporate and CSR consultancy in relation to nutritional issues, plus consumer work for Ribena.
Watkins is now working for Danish pharma firm Nycomed, based in Roskilde. He is believed to be working in an internal comms role.
