Antihistamines
Antihistamines are medications that help relieve allergy symptoms like sneezing, runny nose, and itching by blocking the action of histamine, a substance in the body that causes these reactions. When you encounter allergens, such as pollen or pet dander, your body releases histamine, leading to discomfort. Antihistamines can be taken as tablets, liquids, or nasal sprays and are available both over-the-counter and by prescription. They come in two types: first-generation, which can cause drowsiness, and second-generation, which are less likely to do so, making them preferable for daytime use.
