Care Allergy Defence is a unique nasal powder spray which is clinically proven to relieve the symptoms of hayfever and airborne allergies. Based on inert natural cellulose powder, Care Allergy Defence reacts with the moisture within the nose to form an invisible gel barrier that blocks allergens and protects the nose. This helps prevent an allergic reaction. Care Allergy Defence is both antihistamine and steroid free and has no known side effects, or interactions with other medicines. Therefore it is suitable for all including, children (from 18 months) and pregnant and breastfeeding women.
