Not related: Poison ivy is a different type of allergy. It is a rash that starts 12-24 hours after it touches your skin and worsens up to 48 hours later. It does not usually cause anaphylaxis .

Itchy rash: Typically one gets a very itchy blistering rash in the areas which contacted the poison ivy. But one can even transfer the oils to other parts of the body if not careful.

It is not contagious: I agree w dr. Chiu. Urushiol (offending chemical in poison ivy) remains potent for over a year. So it is imperattive that you wash any tools, clothes, boots, etc that have been in contact with ivy. Wash skin asap. There are specific products that you can buy that will wash the urushiol off very effectively. You can also use rubbing alcohol to remove the urushiol. ...Read more
