Fast-dissolving sublingual tablet-based immunotherapy (SLIT) containing biological extracts of birch tree allergens for desensitisation. Taken for 3 years.
Most allergenic tree pollen in north, central and eastern Europe is the birch (Betula) pollen [1]. Overall prevalence of 23% in allergic rhinitis was identified among European adults in a population-based survey in Belgium, France, Germany, Italy, Spain, and the UK in 2001 [2]. Prevalence of rhinoconjuctivitis among adults in the UK in 2001 was about 15% [3]. ALK estimates 15 million Europeans have tree allergies of which 10% are not well controlled with conventional symptomatic medicines [4].
