How to Identify the Products
Your Patients Are Exposed To
The nomenclature of pesticides is
similar to medications in that they
have….
•
•
•
A brand/trade or product name: e.g. Motrin
A generic name (common name or active
ingredient): ibuprofen
A chemical family: e.g. NSAID
Likewise one needs to know the chemical family
and more specifically the common name to
understand the health effect of an exposure and
how to treatment a poisoning.
What the Patient Will Know ?
NOT the common or chemical family name.
More likely they can identify:
• BRAND name
• TYPE of pesticide (insecticide, herbicide, fungicide,
fumigant)
• CROP to which the pesticide was being applied.
Pesticide Product Label
• The label is the agriculture world = the
package insert for the medical world
• The label is the LAW and dictates:
– Use
– Required personal protective equipment
• The label on the bottle or package provides
basic information

• Agricultural workers know pesticides
primarily through the brand name
• Companies will keep brand names but
CHANGE the active ingredients (e.g. Raid)
• Can use brand name as a search term

• Critical identifier of the chemical
• Some databases only allow you to search by
common name.
• Basis of treatment!
