Nasal sprays are small pumps that spray medicine into the nose, and are used for clearing congestion of the nose in case of an allergy or cold. Sprays containing antihistamines are used for allergies, like those caused by pollen or dust. Steroid and decongestant nasal sprays help in ailments like sinus, and saline sprays are used to alleviate irritation and dryness of the nasal cavity.
