Name  a prescription drug in a TV  ad, and you also take to name all the side effects. 
But  if you talk about a condition rather than a drug, you can dispense with the side-effect blab out and transmit people to a Web  site � which in turn promotes your drug.
So-called  �unbranded mathematical product advertising� has been around for a while. But  with direct-to-consumer drug ads facing scrutiny recently, the soft sell is having a revival, the WSJ  reports.
 In  a single week, Sanofi-Aventis�s  �silence your rooster� ads (pictured) drove 400,000 people to this Web  site that advertises the company�s sleeping pill Ambien.

And  Pfizer,  whose smoking-cessation drug Chantix  has come under scrutiny for psychiatric side effects, has recently revived ads that send people to mytimetoquit.com.
The  site gives readers lots of options to �learn about a prescription treatment option� � which turns out to mean clicking through to the Chantix  Web  site. 
The  campaign isn�t designed to circumvent FDA  rules, Pfizer  spokeswoman Sally  Beatty  tells the WSJ.  �My  Time  to Quit  is designed to encourage people who are thinking about quitting to speak to their health-care provider about the benefits of quitting smoking and available treatment options,� she said.
