Aerius

Oral antihistamines are effective in reducing the symptoms caused by your body's reaction to allergens. They work by blocking the action of histamine, a substance produced by the body in response to allergens like dust and dust mites, pollen from ragweed, grass, trees, or fur from dogs and cats.

Aerius uses desloratadine, a metabolite of loratadine, to make a powerful and long-lasting antihistamine. It has been proven to effectively relieve nasal congestion without an added decongestant like pseudoephedrine.
