This medicine is authorised for use in the European Union.


Lonquex is a medicine that contains the active substance lipegfilgrastim. It is used to reduce the duration of neutropenia (low levels of neutrophils, a type of white blood cell) and the occurrence of febrile neutropenia (neutropenia with fever) in patients with cancer aged 2 years and older receiving cytotoxic chemotherapy.

Cytotoxic chemotherapy (medicines that kill fast growing cells) commonly causes neutropenia because as well as killing cancer cells, it also kills other fast-growing cells such as neutrophils, leaving the patient at risk of infections.

Lonquex is not used in patients receiving chemotherapy for chronic myeloid leukaemia (a cancer of the white blood cells) and myelodysplastic syndromes (a disease that can develop into a leukaemia).
