Stacy Wiegman answered:Antihistamines are used to relieve or prevent allergy symptoms. When your body is exposed to allergens, it releases histamines. Histamines can cause itching, sneezing, runny nose and watery eyes. Antihistamines prevent histamines from causing these symptoms.
An antihistamine can be taken by mouth, through a nasal spray or as an injection.
