Allergic rhinitis is a common condition caused by an allergic reaction to airborne substances such as pollen, dust mites, mold, or pet dander. When exposed to these allergens, the immune system releases chemicals like histamine, leading to symptoms such as sneezing, a runny or blocked nose, itchy eyes, and throat irritation. It can occur seasonally, especially during spring and fall, or year-round depending on the trigger. While not usually serious, allergic rhinitis can affect sleep, concentration, and daily comfort. Management often includes avoiding triggers, using antihistamines, nasal  sprays, and maintaining clean indoor environments to reduce allergen exposure. Pharmacists now have more access to products to help with allergic rhinitis without having to see your doctor.
