Nasal Spray

A Nasal spray is a simple drug delivery device. It is used to deliver medications directly to the nasal cavity. They are used locally for conditions such as nasal congestion and allergic rhinitis. It works by shrinking the blood vessels and tissues in the nose which becomes swollen and inflamed due to cold, allergies or flu. A nasal spray can go a long way in controlling the symptoms of allergic rhinitis or a nasal allergy. It works best when used regularly and consistently.
