Defining Consumer Antiseptics –
FDA
• Panel defined ‘antimicrobial soap’:
– Reduces the microbial flora of the skin
– May reduce residents and transients
• 1978 TFM: intended for the general
public in non-hospital settings
• 1994 TFM: called ‘antiseptic handwash’
Nonprescription Drugs Advisory Committee

10
Labeling Claims
• 1974 ANPR and 1978 TFM:
– Antimicrobial/ antibacterial soap
– Deodorant soap/ reduces odor
• 1978 TFM:
– Different uses require different labeling
for consumers and healthcare personnel
– Insufficient data to accept claims for
‘prevention of infection’
Nonprescription Drugs Advisory Committee

11
Labeling Claims
• 1994 TFM:
– Antiseptic/ antiseptic handwash
– For handwashing to decrease bacteria
on the skin
• After changing diapers
• After assisting ill persons
– Recommended for repeated use
• 2003 Citizen Petition (SDA/CTFA):
– Request anti-viral claims

Proposed Consumer Antiseptic
“Handwash” Attributes – Industry

Potential Hazards from Using
Consumer Antiseptics
• Individual
– Irritation
– Contact dermatitis
– Antibiotic resistance
– Incomplete immune system ‘education’
• Societal
– Antibiotic resistance
– Impact on ecosystems
– Secondary exposure
Nonprescription Drugs Advisory Committee
October 20, 2005
18
Concerns Raised by the 1972 Panel
• Routine use of antimicrobials may have a
long-term harmful effect by reducing normal
flora (hypothetical)
• Widespread use of antibiotics, antiseptics,
and hard surface disinfectants may produce
an increase in gram-negative infections
• Exposure of the entire body to antimicrobial
chemicals when alternate methods of odor
control are available
Nonprescription Drugs Advisory Committee
October 20, 2005
19
Concerns Raised by FDA
• Proliferation of triclosan-containing products
– In 1994 TFM, based on new information,
concluded that proliferation was not a
concern
• Antibiotic and antiseptic resistance related to
healthcare antiseptics (1997 NDAC)
– Decreased susceptibility to antiseptics was
not a concern at that time
– Recommended surveillance
Nonprescription Drugs Advisory Committee
October 20, 2005
20
Current FDA Concerns
• Antibiotic and antiseptic crossresistance
• Environmental concerns
– Secondary exposure
– Impact on ecosystems
Nonprescription Drugs Advisory Committee

21
What Do We Need to Know?
• Finalizing the Monograph
• Need NDAC input to develop some
policies
– What population would benefit from
consumer antiseptics?
– How do we measure the benefit of
these products?
– Which potential hazards, if any, pose
a concern?
