Spring editions of the Thomson Local directory will include a 64-page guide based on NHS Direct's Not Feeling Well publication. It will contain healthcare advice and information.
The guide will be distributed to more than 18m households by next April.
Earlier this year, Thomson Local awarded its £4m ad business to Miles Calcraft Briginshaw Duffy following a four-way pitch. The agency will create TV and online ads.
Its latest directory will contain expanded versions of maps of local town centres.
