How do inhaled steroids work to give allergy relief?
Because inflammation is a key factor in allergies and allergy symptoms, inhaled nasal steroids are the most effective medications to give allergy relief. These prescription allergy relief medications help to prevent or reduce inflammation in the nasal passages and sinuses when exposed to allergens (pollen, animal dander, or dust mites). Inhaled nasal steroids do not give immediate allergy relief from allergy symptoms. You will probably notice allergy relief — decreased swelling and mucus production — within one to two weeks of starting a nasal steroid spray. Inhaled nasal steroids must be used every day for continued benefit.
