As a result, you may experience sneezing, congestion, and a runny nose. These allergies are often caused by pollens from trees, grasses, and weeds. People who have perennial allergic rhinitis have allergies all year long. These people suffer from year-round exposure to triggers such as dust mites, mold, and dander from pets, especially cats. In people suffering from allergies, corticosteroids like budesonide reduce production of mucus and swelling in the nose.
Corticosteroids are similar to some hormones produced naturally in our bodies.
Many different corticosteroids produced by our bodies influence metabolism, reduce inflammation, and help control salt and water balance and the functioning of the immune system. Nasal-inhaled corticosteroids are safe and effective in treating nasal allergies when used as prescribed by your doctor. As with all medications, talk to your doctor about any side effects you may experience. Patients who are using corticosteroids, which can suppress the immune system, are more susceptible to infection than healthy individuals. This suppression could result in a much more serious infection or illness than would normally occur.
