Could treating hay fever earlier help protect against asthma later?
New evidence in allergy medicine suggests that early SLIT immunotherapy may do more than reduce symptoms — it may help change the long-term course of allergic disease in selected patients.
SLIT (sublingual immunotherapy) is a specialist allergy treatment designed to gradually train the immune system to tolerate allergens such as:
• Grass pollen
• Tree pollen
• House dust mites
• Animal dander
Recent studies suggest potential benefits may include:
* Reduced allergy symptoms
* Less reliance on antihistamines and nasal sprays
* Fewer asthma flare-ups
* Possible reduction in asthma progression in some patients
Early assessment is important, especially for persistent hay fever symptoms or allergic asthma.
Every patient is different, and treatment suitability should always be assessed by an allergy specialist.
Book a consultant-led allergy assessment to discuss whether SLIT may be appropriate for you or your child.
