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.

An allergist can assist in the diagnosis and interpretation of these tests. ...Read more

Allergy to tree nuts & peanuts probably occurs because exposure is too low during the critical period when the infant's immune system is sorting out self from dangerous stuff & foreign but safe stuff.

If the husband has nut allergy does that mean our children can have it?

Possible: If one or both parents have allergy, the risk for the child to have allergy increases dramatically. However, they do not inherit the specific allergy directly. They become allergic based on their own exposures. So they may not have the same set of allergies as their parents. Be cautious. ...Read more
