Thousands could benefit from first immunotherapy for severe birch tree pollen allergy
21 July 2025 - We have recommended the first under the tongue tablet immunotherapy shown to build long-term tolerance to allergens, which could help up to 27,000 people in England with moderate to severe birch tree pollen allergies.
The treatment, betula verrucosa (Itulazax 12 SQ-Bet) which is made by Alk-Abelló, for severe hay fever (allergic rhinitis or conjunctivitis), offers the potential for long-term rather than temporary symptom relief for this debilitating condition.
NICE recommended the therapy in final draft guidance published today.
