Q: Propofol should be given with caution in which common allergy?


A: Egg allergy

Originally propofol was launched 32 years ago but was withdrawn from the market due to reports of anaphylactic reactions. It was re-launched in 1986 by AstraZeneca with the brand name Diprivan with preparation containing 10% soybean oil and 1.2% purified egg lecithin, a phosphatidylcholine found in egg yolk.

A history of egg allergy does not necessarily contraindicate the use of propofol. Most egg allergies are related to a reaction to the egg white (albumin) and not to the egg yolk (lecithin). This could explain why 'propofol' is only very rarely a problem. However, a patient who has an egg allergy should be carefully questioned.

  1. You mentioned pts with an egg allergy should be carefully questioned. Questioned about what? So if mild reaction it is ok?

    What about soy allergy?
