Researchers from the University of Goteborg, Sweden, have found that an intranasal cellulose powder significantly reduced allergic rhinitis symptoms in children. The double-blind study involved 53 children with allergies to birch pollen.
Nils Åberg, associate professor at the Department of Pediatrics and consultant at the Queen Silvia Children’s Hospital remarked,”The cellulose powder has no adverse effects, and this fact makes it a particularly attractive treatment for children. It is used increasingly in many countries, but there is until now no scientific study proving the efficacy of the cellulose powder in children during the pollen season.”
Several companies offer products, including Nasaleze in the US and NozoAir in Australia, that deliver micronized cellulose powder through a nasal spray pump.
Results of the study are being published in the June issue of Pediatric Allergy and Immunology.
