Allergy shots involve the administration of an allergen (such as pollens, pet dander, molds, and dust mites). It would seem like this would worsen allergy symptoms, but when allergens are injected in low doses, the immune system sometimes responds to the allergens similarly to how it responds to a vaccine.
Immunotherapy starts with small doses of an allergen that aren‘y enough cause an allergic reaction, then gradually increasing doses until larger amounts of the allergen can be tolerated.
Injections are initially given one to three times a week until a maintenance dose is reached. It may take 3 to 6 months to reach the maintenance dose.
Once reached, the maintenance dose will usually promote the resolution of most of a person’s allergy symptoms. At this point, allergen injections are given every two to four weeks for 3 to 5 years.

Safety Considerations
Allergy shots can be continued during pregnancy, but starting this treatment during pregnancy is not recommended.
If you are taking allergy shots and think you might become pregnant or are already pregnant, it is important that you discuss the risks and benefits of continuing your allergy shots during pregnancy with your allergist and your obstetrician.
