Mosquitoes are a nuisance to many of us, but far more so to those who are allergic to their bites. Avoiding mosquito bites is best, but a study presented at the annual meeting of the American Academy of Allergy and Immunology is good news for mosquito-sensitive children (and adults). Taking a non-sedating antihistamine such as loratadine (Claritin) before the bite can greatly reduce the reaction -- both the swelling and the itching. If you know when your children are most likely to be exposed, you can go along way toward preventing their discomfort.
