Appropriate medical support should be readily available when ALDURAZYME is administered [see Precautions].
Patients with compromised respiratory function or acute respiratory disease may be at risk of serious acute exacerbation of their respiratory compromise due to infusion reactions and require additional monitoring [see Precautions].
