A water-based nasally inhaled corticosteroid spray, taken once a day, has been found to relieve hay fever symptoms in children as young as 6, according to research published in the January 1996 Journal of Allergy and Clinical Immunology.
The trial focused on 223 children, age 6 to 12, with a history of hay fever induced by allergy to spring grass. Their symptoms were not adequately controlled by antihistamines, decongestants or immunotherapy.
Once a day for two weeks, some subjects received a placebo while some received the investigational corticosteroid nasal spray.
The corticosteroid spray was more effective at relieving such allergy symptoms as runny nose, stuffiness, sneezing and itching. Improvement occurred as early as the first day of treatment.
