What are antihistamines used for?

Explanation:
Antihistamines work by blocking histamine from binding to H1 receptors, which dampens the body's allergic response. This reduces common allergy symptoms such as sneezing, itching, runny nose, and watery eyes, and can also help with hives. While some older antihistamines may be sedating and used for sleep, their primary role is treating allergy symptoms. They are not used to treat depression or seizures, which involve different medications and mechanisms.
