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).
The amount of allergen is increased gradually until it reaches the maintenance phase. Many patients already see results during this phase, but it may take longer for some people before they can feel the effects of immunotherapy. When the maintenance phase is reached, allergy shots are given once or twice a month for a period of three to five years. Some patients may stop on their third year while others may continue to five years depending on how well their immune systems react to the treatment.
