How can allergy shots help when you have allergic asthma?

ANSWER

To help prevent asthma flares when you have allergic asthma, it may be helpful to use allergy shots to “train” your body not to overreact when exposed to allergens. Doctors (typically allergists) inject you with gradually rising amounts of the allergen to help your immune system become more tolerant when exposed to it. Allergy shots can cause your reactions to become milder or disappear.
