In the “build-up” phase, you’ll need a shot once or twice a week for about three to six months. Based on how your medications are working or your history of symptoms, your allergist may recommend immunotherapy, or allergy shots that will help your body build tolerance to your allergens. This is typically a 3- to 5-year time commitment. In that case, your allergist will want to retest you. During the build up phase, the strength of the allergy vaccines is gradually increased by a fixed schedule to reach a target dose referred to as the maintenance dose. Shot are normally given 1 to 2 times per week initially. This duration is normally 3 to 6 months depending on how often shots are received.
