Myths versus Facts


Myth: Scratching poison ivy blisters will spread the rash.
Fact: The fluid in the blisters will not spread the rash. Before blisters
form, the rash can only be spread by unbound urushiol. Avoid scratching of
blisters. Fingernails may carry bacteria that could cause an infection. 


Myth: Poison ivy rash is "contagious."
Fact: The rash is a reaction to urushiol. The rash cannot pass from person
to person after the urushiol binds. 


Myth: After the first time, I can't get poison ivy again.
Fact: Although not everyone reacts to poison ivy upon first or subsequent
exposures, people generally become more sensitized with each contact and may
react more severely to subsequent exposures. In addition, the reaction may
last longer. 


Myth: Once allergic, always allergic to poison ivy.
Fact: A person's sensitivity changes over time, even from season to season.
People who were sensitive to poison ivy as children may not be allergic as
adults. 


Myth: Dead poison ivy plants are no longer toxic.
Fact: Urushiol remains active for up to five years. Never handle dead plants
that look like poison ivy without proper protection.
