This year will likely prove to be one of the busier camping seasons as many Americans bypass more expensive vacations that involve pricey airline tickets or gas guzzling road trips. Emergency department staff will probably see a greater number of people with contact dermatitis caused by exposure to poison ivy, poison oak or poison sumac.

Allergic reactions happen when your body is sensitive to a specific substance. The reaction can happen when you swallow or inhale the substance or when it is applied to your skin or injected or transfused through an IV into your body.
Allergic reactions can take many forms.
Mild allergic reactions include:
runny or stuffy nose
watery, itchy, red eyes
Moderate or severe allergic reactions include:
swelling of the face, eyes, or tongue
wheezing or difficulty breathing
nausea and/or vomiting
passing out/becoming unconsciousness
Severe allergic reactions are known as anaphylaxis.
Any breast cancer medication can cause an allergic reaction:
Arimidex (chemical name: anastrozole)
Aromasin (chemical name: exemestane)
Femara (chemical name: letrozole)
Evista (chemical name: raloxifene)
Fareston (chemical name: toremifene)
