How XYZAL works
If you have indoor and/or outdoor allergies, you may know that breathing in allergens like pollen or dander causes your immune system to release a chemical substance called histamine into your bloodstream.
Once histamine is released, it attaches to proteins in the body called histamine receptors, which then trigger your allergy symptoms. By blocking histamine from attaching to certain cells, XYZAL relieves your allergy symptoms.
