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).
Usually, youâll stay at the doctorâs office for about 30 minutes after receiving an allergy shot to make sure you don't develop side effects like itchy eyes, shortness of breath, runny nose, or tight throat. If you get these symptoms after you leave, go back to your doctor's office or to the nearest emergency room.fter that, youâll usually get a shot every 2-4 weeks for 4-5 months. Then your doctor will gradually increase the time between shots until youâre getting them about once a month for 3-5 years. During that time, your allergy symptoms will get better and may even go away.
