Even without the Internet, FDA officials would have trouble keeping up.
Congress has helped deliver a handful more staffers to help tackle the growing flood of ads, but the agency still has just 57 officials charged with reviewing roughly 75,000 marketing items a year, Abrams noted. They review "thousands and thousands" but can't get to them all, he said.
As a result, agency officials say they must prioritize which promotions get checked first. Those that could have the biggest effect on public health top the pile.
To make matters worse, Congress moved to allow industry funds to boost FDA ad reviews but never fully authorized the program. Companies could have voluntarily paid a fee to have the FDA screen their television commercials before they ran, rather than later when they could get a warning.
FDA Commissioner Margaret Hamburg, who took over in May 2009, has said staffers simply can't cope with the volume. "We're sort of always running to keep up," Hamburg, a former New York City health chief and public health expert, told lawmakers at a U.S. House of Representatives appropriations subcommittee in March.
"We do review the ads and can take action when we think there are misrepresentations or inadequate presentation of risks, but the volume makes it very, very difficult," she said. "The fact is: we don't review them, sign off, and then they go up."
Insufficient staff isn't the agency's only problem. It is also hampered by antiquated technology systems.
At a time when digital videos take seconds to upload and can reach millions of views in minutes, the FDA's marketing reviewers read storyboards of television and Internet spots on paper, which are archived in a separate room across the agency's 130-acre campus. As with other government entities, the division is moving toward electronic submissions but isn't there yet.
To ease the workload, the agency recently enlisted doctors to report misleading promotions aimed at medical professionals. Its "Bad Ad" campaign seeks to teach physicians how to spot questionable promotions or statements and then report them to the agency voluntarily.
So far, it has received about 100 complaints through the effort.
Nevertheless, consumer activists say FDA's overall approach is likely to fall short. Abrams' office "certainly needs more money and manpower to be regularly monitoring this kind of stuff," said Steve Findlay, a senior health policy analyst for Consumers Union, an independent non-profit group aimed at protecting buyers.
Findlay said the industry's efforts at self-policing have helped, especially among larger companies, but some companies have clearly crossed the line. "We're still seeing drug ads that are not completely balanced and are inappropriate or off-base," he said.
Consumer advocates worry pharmaceutical companies are increasing efforts to reach teenagers through online ads.
Allergan used a "High School Musical"-type promotion for prescription acne drug Aczone featuring "Twilight" movie actor Michael Welch. He starred in an online video series called "Aczone: The Musical."
Other companies have created stuffed animals, games and children's books to promote medicines to youth, said Susan Linn, director of the Campaign for a Commercial-Free Childhood, a group of doctors, parents, teachers and other advocates.
"It's not a good idea to start kids on a life of choosing drugs based on whether they are cool, or whether some celebrity is promoting them," said Linn, who believes marketing of medicines to children should be outlawed.
Allergan spokeswoman Caroline Van Hove said the Aczone campaign was appropriate because the drug is approved for ages 12 and older. The musical website was "just one of many informational tactics" to educate patients about what at the time was the first new FDA-approved acne medicine in a decade, she said.
PhRMA's Francer said the vast majority of ads don't merit any regulatory action. He added that it can be extremely hard, especially with television commercials, to convey all of a medication's risks. "It can be incredibly challenging for the companies to present all of the risk information that both they and the FDA want to be presented in a way that is understandable to patients," he told Reuters.
In Bayer's case, the New York blogger and another one in Columbus, Ohio wrote about the parties immediately afterward, mentioning both the website that helped organize them as well as the birth control device being touted.
Although studies show that drug ads work -- consumers who see them are more likely to ask their doctors about the product -- it is unclear whether the company's events to promote Mirena had any impact beyond the small parties' audience.
"I went to a brunch yesterday that was hosted by Mom Central and Bayer Healthcare, and they brought in two speakers. One to talk (humorously) about their Mirena birth control product, and the other to give us 'frazzled moms' some basic style tips... The speakers knew their stuff, and did a good job," read one account on www.sanemoms.com that then focused only on fashion.
Another shorter post, at chefdruck.blogspot.com, also only mentioned Mirena in passing in favor of tips on shoes and husbands. "We had an amazing evening, talking about sex, fashion, and living a simpler life," it said.
Stacy DeBroff, chief executive of Mom Central, likened the parties to a focus group, but said her website won't partner with any other drugmakers until the FDA clears up its rules. "For us, it was kind of an experiment of sorts ... If we bring people into your living room what happens?" she told Reuters.
Still, the FDA did not find out about the Tupperware-like party pitch or the online posts until months after they hit the blogosphere and the agency received a complaint. Abrams declined to say who filed the grievance.
Bayer Healthcare, a unit of the German drugmaker Bayer AG, said it stopped holding the parties 10 months before it even received the agency's letter.
In comments to the FDA over social media policies, the German drugmaker said the agency should open up channels to market products and embrace the use of technology, not restrict it. "Any FDA approach should seek to maximize the dissemination of accurate healthcare information to patients and their caregivers," Bayer's senior counsel Christopher Cannon wrote earlier this year. The FDA, he added, should allow drugmakers to be "using the full spectrum of social media and other tools available via the Internet."
Abrams, age 55, said he personally uses Facebook but still relies on his younger staffers to keep up with technology. "I'm not that sophisticated," he joked.
He also said his division will continue to be aggressive in rooting out suspect marketing. One ad reviewer, he said, recently called in on her way to vacation in Florida, having seen a misleading television ad for an erectile dysfunction suppository at the airport.
As for Abrams, he keeps a pad of paper by his television for some evenings when he is watching with his wife, Maureen. "I can be watching TV with my wife after our kids go to bed, and she knows ... when a drug commercial comes on: no talking," he said.
