1 Some babies are so sensitive to these foods that if the offending food is eaten by the mother, drinking her breast milk can cause a reaction. 2  Most children outgrow allergies to eggs, milk, wheat, and soy. 3  Peanuts, tree nuts, fish, and shellfish cause most of the allergic reactions in teens and adults.
Side effects can include skin discoloration and irritation. Long-term use, especially of stronger prescription corticosteroids, can cause thinning of the skin and disruption of normal hormone levels. Examples include: 1  Betamethasone (Dermabet, Diprolene, others). 2  Desonide (Desonate, DesOwen). 3  Hydrocortisone (Cortaid, MiCort-HC, others). 4  Mometasone (Elocon).
How do allergy shots work? Allergy shots help relieve allergy symptoms by changing the way your body reacts to the allergen that causes your allergy. When you get shots of the allergen, your body starts making antibodies that fight against the allergen. These antibodies help block the effects of the allergen the next time you have contact with it. Because the antibodies block the way your body reacts to the allergen, your allergy symptoms become less severe.
