Can EpiPen® be used in sulphite-allergic patients?

EpiPen® contains sodium metabisulphite, a sulphite that may in other products cause allergic-type reactions, including anaphylactic symptoms or life-threatening or less severe asthmatic episodes in certain susceptible persons.
In a patient with documented sulphite sensitivity, the alternatives to using adrenaline in a life-threatening situation may not be satisfactory. Therefore, the presence of a sulphite in this product should not deter administration of the drug for treatment of serious allergic or other emergency situations when sulphite-free alternatives are not available.
