Allergies are common and can be chronic, with symptoms that range from mild to miserable to life-threatening. Allergic reactions start in the body’s immune system. The body reacts to an otherwise harmless substance an allergen as if it is an invader. Common allergy triggers include pollen, house dust mites, mold, grass and ragweed, just to name a few. Exposure can cause symptoms such as sneezing, a stuffy or runny nose, and itchy, watery eyes that can worsen over time if not treated appropriately. Allergic rhinitis, or “hay fever,” symptoms, such as these, can be seasonal or occur throughout the year.

Globally, more than 400 million people suffer from allergic rhinitis, which is widely underdiagnosed and undertreated.3 However, there are several treatment options, including symptom suppressing medicines and allergy immunotherapy. Immunotherapy treats the underlying cause of allergy and can offer long-lasting improvement by reprogramming the immune system to better cope with exposure to specific allergens.
