Allergy Nasal Spray Might Affect Children's Growth
Feb. 28, 2000 (Minneapolis) -- If your child uses a nasal spray for allergies, you might want to take heed. Two studies in this month's Pediatrics go nose-to-nose to evaluate the effects of two commonly prescribed nasal steroid sprays. One of them, researchers find, can slightly suppress childhood growth.
Typically, nasal steroid sprays are used to treat allergic rhinitis, a disease affecting up to 10% of children and 20% of adolescents and adults. The use of nasal sprays as a first-line therapy for children with persistent allergic rhinitis has gained acceptance in recent years because the sprays are well tolerated and effective for treating nasal symptoms.
In the separate studies, researchers evaluated the effects of the two nasal sprays on childhood growth. Each of the studies followed approximately 100 children for a year. One found no evidence of growth suppression using a new treatment called Nasonex (mometasone). The other found that an older treatment, Vancenase (beclomethasone), might slightly slow the growth rate in children.
"There are definite differences among nasal preparations used to treat allergies in both children and adults," Eric J. Schenkel, MD, author of the Nasonex study, tells WebMD. Although Nasonex has been shown to be effective and safe, it should be taken in the lowest dose possible, he says. Schenkel is director of the Valley Clinical Research Center in Easton, Pa.
In the study on Vancenase, researchers found that a small percentage of patients using the medication showed a slight growth suppression as early as a month after beginning treatment. In an interview with WebMD, lead researcher David P. Skoner, MD, tells parents that if a child uses this spray in the right doses on the right timetable, "there's a small chance that he could have a growth suppressive. However, if the child is doing well, there's no reason to change." Skoner explains that the growth suppression found in the study equated to less than half an inch during the yearlong trial. "That's a tiny amount, and most kids that [take] these drugs don't have growth suppression. We need to keep all of this in perspective," says Skoner, who is chief of the Allergy/Immunology Section at the Children's Hospital in Pittsburgh.
