Allergy shots may soon be replaced by a pill according to European researchers. The latest study supports previous research which showed the effectiveness of the Grazax allergen tablet. Hay fever and other allergies have long been treated with allergy shots.
Allergies are a result of the immune system reacting to a normally harmless substance, such as dust mites.
Immunotherapy is supposed to enhance tolerance of the immune system for the allergy-causing substance by exposing the body to small amounts of it over time.
The inconvenience and discomfort of immunotherapy often deters allergy sufferers from getting immunotherapy.
Patients must get weekly allergy shots for several months, and then monthly ones for several years.
Dr. Ronald Dahl of Aarhus University in Denmark proposes that Grazax, a grass allergen tablet, rapidly dissolves under the tongue and this could be an easier alternative for patients.
Grazax has already been approved in Sweden and its manufacturer, ALK-Abello, is applying for approval in other European countries.
