Perennial allergic rhinitis is a condition that causes ongoing nasal symptoms throughout the year, often triggered by indoor allergens such as dust mites, pet dander, or mold. Common symptoms include sneezing, a runny or congested nose, and itchy eyes. These persistent symptoms can disrupt sleep, reduce concentration, and negatively impact overall quality of life.

While standard treatments such as nasal sprays and allergen avoidance can help, they may not fully relieve symptoms. Clinical trials offer access to new and emerging therapies designed to improve symptom control, reduce inflammation, and help individuals breathe more comfortably year-round.
