One of the recent advances in managing allergies is immunotherapy. Building an immune tolerance can spare the patient a life-long need for antiallergic medications and their side effects, especially in mild allergic conditions like allergic rhinitis and sinusitis.

In the past and following allergic testing, the specific allergen that triggers symptoms was injected under the skin in small doses intermittently over a period of time to build a tolerance against that specific allergen. This modality has recently been replaced for some allergens including dust mites -one of the commonest allergens for allergic rhinitis and asthma- and pollen and has shown high efficacy in controlling the symptoms of hay fever.

Tablets containing the allergen are placed under the tongue for extended periods without the need for injections.
