Allergy shots may help if your child has allergic asthma that can't be easily controlled by avoiding asthma triggers. These shots are given over time to stop or reduce allergy attacks that cause asthma symptoms to flare. The shots also are known as immunotherapy.
First, your child receives skin tests to find out which allergy-causing substances, also called allergens, may trigger asthma symptoms. During these tests, the skin is exposed to possible allergens. Then your child is closely watched for symptoms of an allergic reaction.
Once the allergens that trigger your child's asthma are found, your child gets a series of shots. These injections contain small amounts of those allergens. Your child likely will need allergy shots once a week for a few months. Then the shots are needed once a month for 3 to 5 years. Your child's allergic reactions and asthma symptoms should get better over time.
The biologic treatment omalizumab can help allergic asthma that isn't well controlled with inhaled corticosteroids.
