Prescribing information



Xolair is indicated as add-on therapy for the treatment of chronic spontaneous urticaria in adult and adolescent (12 years and above) patients with inadequate response to H1-antihistamine treatment.2

CSU is a disabling condition that can have a devastating impact on patients’ quality of life and a considerable impact on healthcare resources.1,3,4 The 2021 international EAACI/GA²LEN/EuroGuiDerm/APAAACI guidelines state that the "goal of treatment is to treat the disease until it is gone and as efficiently and safely as possible aiming at a continuous UAS7 = 0, complete control and a normalisation of quality of life."1

It is imperative that patients are monitored regularly from diagnosis to establish their level of disease control, so that treatment can be optimised accordingly. Find out more and download monitoring tools here.

Xolair (omalizumab) is widely recognised in key guidelines/recommendations relevant to the UK and internationally.1,5,6

This 2021 update and revision of the international guideline for urticaria was developed following the methods recommended by Cochrane and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) working group.

It is a joint initiative of the Dermatology Section of the European Academy of Allergology and Clinical Immunology (EAACI), the Global Allergy and Asthma European Network (GA²LEN) and its Urticaria and Angioedema Centers of Reference and Excellence (UCAREs and ACAREs), the European Dermatology Forum (EDF; EuroGuiDerm), and the Asia Pacific Association of Allergy, Asthma and Clinical Immunology (APAAACI) with the participation of 64 delegates of 50 national and international societies and from 31 countries.
