Frequently Asked Questions

What are the most common allergy symptoms in children?

Allergies in children include respiratory signs like coughing, sneezing, and nasal congestion, as well as itchy, watery eyes. Other common reactions are skin-related, such as rashes, or gastrointestinal, such as an upset stomach after consuming certain foods. More severe reactions, such as swelling or difficulty breathing, can also occur and warrant immediate medical intervention. For any recurring symptoms, it’s best to consult a pediatric allergist.

How is a child tested for drug allergies?

Figuring out if a child has a drug allergy can be complicated, but our skilled team knows how to manage these situations. We provide thorough drug allergy testing, which can include skin tests, patch tests, or even having your child take a small amount of the drug in a safe, controlled setting (drug challenge) to see if there is a reaction.

If a child must take a medication they are allergic to, we can use a process called drug desensitization. This allows them to get the treatment they need while we carefully manage and reduce the chance of an allergic reaction.

What is the approach to treating children with immune system disorders?

When a child's immune system is not working as it should, it can cause them to get sick often and lead to other significant health problems. Our immunology experts provide comprehensive care for children with various immune disorders, including those affecting antibodies or multiple components of the immune system.

In some instances, advanced treatments such as a bone marrow transplant or gene therapy may be required. We work together with other pediatric specialists to make sure your child gets the most complete care possible, including these specialized therapies.

Do you treat Food Protein-Induced Enterocolitis Syndrome (FPIES)?

Yes, we provide comprehensive diagnosis and management for children with Food Protein-Induced Enterocolitis Syndrome (FPIES). Our approach involves a multidisciplinary team, often including pediatric allergists, gastroenterologists, nutrition specialists, and speech specialists, to ensure your child receives expert, coordinated care. For more information about FPIES treatment, please visit the Pediatric Allergy and Immunology page. 

When should I take my child to see a pediatric allergist or immunologist?*

A consultation with a specialist is warranted for children who experience recurrent or severe allergic events, poorly controlled asthma, or repeated infections. Furthermore, any ongoing symptoms that negatively impact a child's quality of life should be evaluated by an expert. Pediatric allergists and immunologists are physicians with advanced training in the diagnosis and management of these complex medical issues.
