Authors' recommendations: TAP’s searches yielded a smaller number of citations than those of the searches conducted for PBM (2006). Discrepancies likely are due to TAP’s focus on the dental setting and specific study types when conducting its searches, versus PBM’s broader and longer set of search terms.Although FDA is aware of adverse events apparently related to benzocaine sprays, it is not planning action to remove the drugs from the market (FDA Public Health Advisory, February 10, 2006). TAP’s review of this topic indicates that methemoglobinemia is an uncommon event that can also be associated with nitrates, which are ubiquitous environmental chemicals and for which an association of methemoglobinemia with exposure has been more rigorously researched. Therefore, we conclude that an association between methemoglobinemia and topical benzocaine as used in dentistry is insufficiently proven for it to be the basis of major clinical policy or formulary change.
