Warning: Severe hypersensitivity reactions, infusion-associated reactions, and risk of acute cardiorespiratory failure in susceptible patientsHypersensitivity Reactions including AnaphylaxisPatients treated with avalglucosidase alfa-ngpt have experienced life-threatening hypersensitivity reactions, including anaphylaxis. Appropriate medical support measures, including cardiopulmonary resuscitation equipment, should be readily available during avalglucosidase alfa-ngpt administration. If a severe hypersensitivity reaction (e.g., anaphylaxis) occurs, avalglucosidase alfa-ngpt should be discontinued immediately and appropriate medical treatment should be initiated. In patients with severe hypersensitivity reaction, a desensitization procedure to avalglucosidase alfa-ngpt may be considered.Infusion-Associated Reactions (IARs)Patients treated with avalglucosidase alfa-ngpt have experienced severe IARs. If severe IARs occur, consider immediate discontinuation of avalglucosidase alfa-ngpt, initiation of appropriate medical treatment, and the benefits and risks of readministering avalglucosidase alfa-ngpt following severe IARs. Patients with an acute underlying illness at the time of avalglucosidase alfa-ngpt infusion may be at greater risk for IARs. Patients with advanced Pompe disease may have compromised cardiac and respiratory function, which may predispose them to a higher risk of severe complications from IARs.Risk of Acute Cardiorespiratory Failure in Susceptible PatientsPatients susceptible to fluid volume overload, or those with acute underlying respiratory illness or compromised cardiac or respiratory function for whom fluid restriction is indicated may be at risk of serious exacerbation of their cardiac or respiratory status during avalglucosidase alfa-ngpt infusion. More frequent monitoring of vitals should be performed during avalglucosidase alfa-ngpt infusion in such patients .
