Merck's own website states that Singulair is not an anti-histamine. I cannot imagine any General Practitioner receiving a clear picture of how Singulair actually works from this site. Nor, are they being presented with the truth about the side effects. The whole site is a bunch of marketing FLUFF that never gets to the point. At the very least, the GP's should be on the rampage with us for being deceived. I plan to rant about this later. What a dumbed-down presentation (Merck's site)? What an insult? http://www.singulair.com/montelukast_sodium/singulair/hcp/allergies/efficacy/index.jsp
