Following is a summary of some of the important warnings and precautions associated with Lumizyme® (alglucosidase alfa) treatment, as well as the adverse reactions (side effects) most frequently reported during clinical trials. Additional "Important Safety Information" can be found at the bottom of this page. If you have any questions or concerns, you should review and discuss this information with your doctor.
The most frequently reported adverse reactions during Lumizyme studies in patients were allergy (hypersensitivity) reactions and included:
If an infusion reaction occurs, your doctor may temporarily stop the infusion, and/or administer antihistamines (drugs to combat an allergic reaction) and/or anitpyretics (drugs to reduce fever) to help the symptoms.

If you suspect you might be having side effects from your Lumizyme treatment, or any other medication, it's important that you report these experiences to your doctor immediately. You can also report them to Sanofi Genzyme by calling our Medical Information group at, option 2.
LUMIZYME® (alglucosidase alfa) is an enzyme replacement therapy for patients with Pompe disease (acid α‑glucosidase (GAA) deficiency).
WARNING: RISK OF ANAPHYLAXIS, HYPERSENSITIVITY AND IMMUNE-MEDIATED REACTIONS, AND RISK OF CARDIORESPIRATORY FAILURE
Anaphylaxis and Hypersensitivity Reactions: Life-threatening anaphylaxis and hypersensitivity reactions have been observed in some patients during and after treatment with alglucosidase alfa. If such a reaction is severe enough, your doctor may decide to immediately discontinue the infusion and provide you with immediate medical care. Appropriate medical support and monitoring measures should be available during infusion.
Immune-Mediated Reactions: You or your child may be monitored for the development of systemic immune-mediated reactions while receiving Lumizyme. If these reactions occur, your doctor may discontinue the infusion and initiate appropriate medical treatment.
Risk of Acute Cardiorespiratory Failure: Infant Pompe patients with heart or breathing problems who are experiencing an acute respiratory condition may be at risk for increasing the seriousness of these problems as a result of Lumizyme administration due to the infusion fluid, and your child’s doctor may require additional monitoring for these infants.
Risk of Cardiac Arrhythmia and Sudden Cardiac Death during General Anesthesia for Central Venous Catheter Placement: Caution should be used when administering general anesthesia for the placement of a central venous catheter intended for Lumizyme infusion. Ventricular arrhythmias and slow heart rate resulting in cardiac arrest or death have been observed in infant Pompe patients with cardiac hypertrophy during general anesthesia for central venous catheter placement. Appropriate medical support and monitoring measures should be available during infusion.
Risk of Antibody Development: Patients with infantile-onset Pompe disease (IOPD) should be managed by a clinical specialist knowledgeable in immune tolerance induction in Pompe disease to optimize treatment. Some patients who develop high and sustained IgG antibody levels, including certain IOPD patients, may have a reduced response to Lumizyme.
Monitoring: Laboratory Tests: Patients should be monitored for IgG antibody formation every 3 months for 2 years and then annually thereafter.
The most frequently reported adverse reactions during Lumizyme studies in patients were allergy reactions and included: anaphylaxis, rash, fever, flushing/feeling hot, hives, headache, excessive sweating, nausea, cough, less oxygen in the blood, fast heart rate, rapid breathing, chest discomfort, dizziness, muscle twitching, agitation, bluish or purple skin, redness of skin, high blood pressure/increased blood pressure, facial paleness, chills, tremor, vomiting, fatigue, and muscle pain.
