Accelerated, or rush, immunotherapy (allergy shots) 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 usual. 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.
It is usually done by a specialist. Having a severe reaction to this treatment is more likely than with standard allergy shots. All shots should be given in a doctor's office or clinic so that emergency care is available.
Rush immunotherapy may be done if:
- You have a life-threatening allergy to insect venom, and the insect season is about to start.
- Shots are only available in a clinic that is far away from your home, and you can't come in once a week for months.
- You are about to travel.
