According to the World Health Organization (WHO), SIT is the only therapeutic option that can change the natural progression of allergy symptoms, preventing the onset of new allergic reactions and slowing down or stopping the progression of the symptoms, thus preventing the onset of asthma in patients with rhinitis.

SIT, when properly prescribed and performed for at least 4 years, generally maintains its clinical benefits for five years after cessation.

SIT has proven effective for allergies to pollen, mites, animal danders, mycophyta and hymenoptera venom and should be regarded as a radical and definitive treatment for allergies because it can:

• reduce symptoms
• reduce pharmaceutical consumption 
• ameliorate the allergy
• prevent complications due, above all, to asthma
• reduce pharmaceutical costs
