FDA has a few questions for makers of hand sanitizer (w/video)

RECOMMENDED READING


WASHINGTON — Federal health officials want to know whether hand sanitizers used by millions of Americans work as well as manufacturers claim — and whether there are any health risks to their growing use.

The Food and Drug Administration is asking for new studies on how the antiseptic gels and rubs fight germs and get absorbed into the body, with a particular focus on children and pregnant women. The proposal unveiled Wednesday is part of an ongoing government effort to review decades-old chemicals that have never had comprehensive federal reviews.

Agency officials stressed that the review "does not mean the FDA believes these products are ineffective or unsafe."

Hand sanitizers have become nearly ubiquitous over the past 20 years, offered in workplaces, schools, restaurants and other public spaces to reduce the spread of germs. Since 2009, about 90 percent of sanitizers sold to the public have included either ethanol or ethyl alcohol, according to agency officials.

Under current regulations, manufacturers can make broad claims about their products' effectiveness in killing germs. Bottles of Purell hand sanitizer, for example, say: "Kills 99.99 percent of illness-causing germs."

FDA regulators suggested they may tighten such claims after reviewing the information submitted by manufacturers.

"We're not trying to alarm people," said Dr. Janet Woodcock, director of the FDA's drug center. "Obviously, ethanol and humans have coexisted for a long time, so there's a lot that's known about it."

But the agency has concerns about the possible long-term consequences of frequent use by children and women of child-bearing age, particularly those who are pregnant or breast feeding. The agency's proposal would require manufacturers to study whether three anti-germ ingredients — ethanol, alcohol and a type of chloride — show up in blood or urine after repeated, daily use. That could mean that the chemicals may be affecting the reproductive system or the production of hormones.

Regulators are also concerned about possible links between use of antiseptic chemicals and the emergence of so-called superbug bacteria, which are resistant to antibiotics.

"We need to get this additional information so if there are situations where caution is warranted, we can label that or inform the public," Woodcock said.
