"But Mommy, I Like the Placebo Effect!" - Possible Changes for Pediatric Cough Syrup & Cold Medicines

NPR's Morning Edition had an interesting story today about the developing research relating to cough and cold treatments for children.  Most were approved a long time ago, and it turns out the evidence for efficacy is, well, not particularly extensive, though there's also not a lot of danger when used as directed.

Some children got the real thing, a combination of dextromethorphan, a standard cough suppressant, along with the antihistamine Benadryl. Other children, unbeknownst to them and their parents, were given a placebo syrup.

"Parents found there was no difference between the two medicines or the placebo in how much their child coughed or how well they slept," Paul says.
