Infusion reactions (some severe) have been reported in 56% of patients despite routine pretreatment with antihistamines. Serious symptoms reported during infusion have included angioedema, laryngeal edema, pyrexia, anaphylactoid reaction, respiratory distress, apnea, and urticaria. Severe symptoms of infusion reactions have included chest pain, dyspnea, apnea, laryngeal edema, conjunctivitis, rash, and urticaria.

Infusion reaction symptoms generally abated with slowing or temporary interruption of the infusion along with administration of additional antihistamines, antipyretics, and occasionally corticosteroids. Most patients were able to complete their infusions. Subsequent infusions were managed with a slower rate of galsulfase administration and treatment with additional prophylactic antihistamines. In patients who had more severe reactions, treatment included prophylactic corticosteroids.
