Environmental and seasonal allergies can be so disruptive and uncomfortable. The good news is that there are many OTC treatment options available, but filtering through and figuring out the right one for your child is tricky. Here is a simple explanation of the best medication for your child’s specific allergy symptom.

Allergies occur when our immune systems overreact to triggers. Antibodies called Immunoglobulin E cause mast cells to release histamine, which then triggers symptoms. Some children are predisposed to allergies. They tend to run in “atopic” families (which means families with asthma and eczema as well as allergies). But it is possible to develop allergies even without a known family history.
