Allergens are common things, like certain foods, animals or bits in the air that can cause allergic reactions in some kids. Kids with allergies have immune systems that treat harmless things like threats. The immune response can lead to symptoms that range from mild to serious. 

Allergens can also trigger asthma symptoms or even cause an asthma attack. Common triggers include pet dander, dust mites, mold and pollen. When a child touches or breathes in one of their triggers, their airways can become irritated, and breathing may become harder. 

Common signs of environmental allergies include: 

• Sneezing or runny nose
• Itchy, red or watery eyes

A food allergy typically presents with:

• Skin rashes or hives
• Swelling of the face, lips or throat
• Stomach pain, nausea or vomiting
• Trouble breathing or wheezing
• Runny nose

Treatment will depend on the type of allergen that triggers your child’s asthma or allergies.  At Children’s Wisconsin, we offer guidance and treatment for all conditions related to allergens.   

Avoidance of Allergens

The best treatment is to avoid the allergens that are causing the problem. Depending on the cause, this may include:  

• Avoiding certain foods
• Staying indoors and using air conditioning during pollen season
• Avoiding areas with heavy dust, mites and mold
• Avoiding pets

If your child has a food allergy, it’s important to avoid that food. We’ll help guide you on what to avoid, how to read food labels and finding safe substitutes. 

For mild to moderate skin reactions, wash the skin well with soap and water as soon as possible after exposure. Wash clothing and all objects that touched the allergen to prevent another reaction. Use a wet, cold compress to soothe and relieve inflammation, or if blisters break open. 

Medicines

Sometimes, your child’s doctor may prescribe or advise medicines to help with symptoms. These may include medicines that reduce:  

• Itching, sneezing or a runny nose
• Swelling inside the nose
• Inflammation, swelling or itching of the skin

If your child has a serious allergic reaction, their doctor will likely treat them with an epinephrine shot. One common brand is an EpiPen. They may instruct you to always carry one with you for emergencies.  

Allergy Shots

If avoiding allergens or medicine doesn’t work, your child’s doctor may suggest allergy shots or immunotherapy. These shots help the body build up a tolerance to allergens.

Oral Immunotherapy for Food Allergies

Gradual introduction of peanut, cashew, milk and egg in those who are allergies can protect against accidental exposure and may even help outgrow the allergies.
