Abstract

The symbol ▾ in the British National Formulary, MIMS, and the Data Sheet Compendium identifies all products introduced during the preceding 2 to 3 years, or in some circumstances longer ago. It informs doctors of the Committee on Safety of Medicines’ particular request for reports of any suspected adverse reaction, however trivial, to such a product. Doctors still make inadequate use of yellow cards. The CSM’s guidelines on what to report are given at the end of this article.
