How severe does a nut allergy need to be to warrant carrying around an epi pen?

How severe does a nut allergy need to be to warrant carrying around an epi pen?

Always carry EpiPen (epinephrine): Peanut and tree nut allergies have some of the highest rates of fatal anaphylaxis, and Epinephrine can be life saving. Unfortunately, you cannot predict how severe a person's reaction will be based on a previous reaction--there are too many variables. For that reason, in general we recommend that everyone with any history of reaction to these foods carry an epi pen. See an allergist for more info. ...Read more

I was diagnosed with a cashew nut allergy as a small child, will i still be allergic 20 years later?

I was diagnosed with a cashew nut allergy as a small child, will i still be allergic 20 years later?

Probably: Only about 10% or less of people with nut allergy actually "outgrow" it. If the reaction was very severe, it is less likely. Since there is a small chance of not being allergic, an allergy skin test and blood test to cashew would be one way to assess if sensitivity is still present. An allergist can assist in the diagnosis and interpretation of these tests. ...Read more

What's my likelihood of developing a nut allergy if one of my parents has one?

What's my likelihood of developing a nut allergy if one of my parents has one?

Great question: Most of the data on food allergy is dealing with milk, egg, and peanut. There is fewer data on nut allergy.

A factor other than genetic factors that may increase the risk of nut allergy is having eczema (atopic dermatitis). ...Read more
