Antihistamines
Antihistamines are a class of medications that are commonly used to treat allergies. They work by blocking the action of histamine, a chemical in the body that is involved in the inflammatory response to allergens. Antihistamines can help relieve symptoms such as sneezing, itching, and watery eyes. They are available in both over-the-counter and prescription forms, and can come in various formulations such as pills, liquids, nasal sprays, and eye drops.
