Propofol and egg allergy are quietly related as one of the side effects. Allergic reactions to propofol on first exposure are usually because of the isopropyl groups that may act as epitopes and that are present in various medications andcosmetics.
Allergic reactions to propofol upon re-exposure are usually because of the phenol molecule. Propofol and egg allergy was more likely in patients with a history of atopy and in those with a history of a drug allergy often to neuromuscular-blocking drugs.
The formulation of propofol administered to these patients was containing soybean oil, glycerin, yolk lecithin, and sodium edetate.
