European Medicines Agency gives guidance for use of antiviral medicines in case of a novel influenza A/H1N1 pandemic
The European Medicines Agency has given guidance on the use of Tamiflu (oseltamivir) in children under one year of age and the use of Tamiflu and Relenza (zanamivir) in pregnant and breastfeeding women in the case of a declared influenza A/H1N1 pandemic.
Children under the age of one
The Agency's Committee for Medicinal Products for Human Use (CHMP) has concluded that during an officially declared influenza A/H1N1 pandemic the benefits of the use of Tamiflu outweigh its risks in the treatment of children under the age of one. Because there is less evidence to support the use of Tamiflu for the prevention of influenza, doctors should carefully consider the benefits and risks for each patient.
During a pandemic, if Tamiflu is prescribed to children under the age of one, the recommended dosage is 2 to 3 mg per kg body weight.
Pregnant and breastfeeding women
Following a review of the available data for Tamiflu and Relenza, the CHMP concluded that the benefits of using these medicines in pregnant or breastfeeding women outweigh the risks in case of an Influenza A/H1N1 pandemic.
The recommendations are made by the Committee as part of a wider request from Agency's Executive Director Thomas Lönngren to look into ways to prevent shortages of antiviral medicines and to ensure that the medicines are available to those who might need them. These recommendations will only apply if a pandemic has been declared by the World Health Organization (WHO).
Unless a pandemic has been announced, Tamiflu and Relenza should be used according to the currently approved product information.
