Accelerated, or rush, immunotherapy is done very quickly to increase your tolerance to an allergen. There are different schedules for the shots that try to achieve a maintenance dose more quickly than standard immunotherapy. For example, a rush immunotherapy schedule might include:
Shots given every few hours instead of every few days or weeks.
Maintenance dose reached in 1 to 8 days.
All immunotherapy should be done in a doctor's office or clinic so that emergency care is available.
