What Are The Side Effects Of Antihistamines?

Antihistamines are usually the first type of medication individuals try when they're treating allergies, as these medications are easier to access and take than more involved treatments like allergy shots and steroids. Antihistamines tend to be effective for mild to moderate allergies. When an individual inhales or touches their allergy trigger, the immune system responds by creating histamines. These chemicals lead to swelling in the nose, runny eyes and nose, and itchiness in the eyes, nose, and mouth. Some individuals also experience an itchy skin rash called hives.
