[Basis to modify the immunotherapy regimen at the Allergy Service, General Hospital of Mexico].
BACKGROUND
In Mexico, the way allergen immunotherapy is performed has remained without changes for many years. Here we present the modifications that have been performed in the General Hospital of Mexico to make immunotherapy more effective.


OBJECTIVE
To show the changes implemented to make immunotherapy faster and more effective by changing the volume of allergy vaccines from 5 or 10 mL to 3 mL, and the theoretical and practical support for the change.


METHODS
The amount of protein delivered in each immunotherapy shot was computed to show how they change along the treatment. Results for schedules for 3, 5 and 10 mL were compared.


RESULTS
Results showed serial rises and falls in protein amount injected every time a new vaccine flask starts to be used. However, in the case for 3 mL vaccines schedules, those changes are less pronounced.


CONCLUSIONS
Due to these results we suggest a schedule of immunotherapy with 3 mL vaccines that allow getting the maintenance doses in a shorter time and at lower cost.
