Article 2
1. Holders of marketing authorisations granted before 1 September 2013 which concern medicinal products for human use that are subject to additional monitoring shall include the black symbol in the summary of product characteristics and the package leaflet relating to these medicinal products by 31 December 2013. 2. By derogation from paragraph 1, holders of marketing authorisations granted before 1 September 2013 which concern medicinal products for human use that are subject to additional monitoring may request a longer period of time to be granted by the competent authorities, where they can demonstrate that compliance with the date referred to in paragraph 1 may unduly affect the appropriate and continued supply of the medicinal product.
