Anaphylaxis

Date: 2023-09-04

Topic: Anaphylaxis

  1. Can a patient have an anaphylactic reaction on 1st exposure to an allergen?

A patient must have had a previous exposure to the offending allergen for sensitization to occur. Therefore, anaphylactic reactions should not occur on 1st exposure. Remember: Infants can be sensitized through breast milk; therefore, a baby may react upon“1st”exposure to a food.

  1. When should the autoinjectable epinephrine be used?

It is intended for severe allergic reactions as manifested by any of the following: bronchospasm, angioedema of the lips or tongue, or hypotension (dizziness). The patient must seek immediate medical help if the autoinjectable epinephrine is required.

  1. Do patients outgrow this condition?

No. Subsequent reactions tend to have a more rapid onset, and tend to be more severe. Children often outgrow food-induced anaphylaxis.

  1. Who should be referred to an allergist?

All patients who have experienced anaphylaxis would benefit from consultation with an allergist. Patients with anaphylaxis from insect stings, fire ants, and certain antibiotics can be desensitized. In addition, the allergist can be helpful in identifying obscure triggers of anaphylaxis.
