Which medication class is indicated for the treatment of allergies?

Antihistamines are the medication class specifically indicated for the treatment of allergies. They work by blocking the action of histamine, a substance in the body that is released during allergic reactions. Histamine is responsible for many allergy symptoms, such as sneezing, itching, and runny nose. By inhibiting this action, antihistamines can effectively alleviate these symptoms, making them a common choice for managing allergic reactions, whether they are due to pollen, pet dander, or other allergens.

The other classes mentioned are used for different medical purposes. Antibiotics, for instance, are designed to treat bacterial infections rather than allergic responses. Antidepressants are utilized primarily to manage conditions related to mood disorders and anxiety, while anticonvulsants are used to control seizures in conditions such as epilepsy. Each of these classes focuses on specific health issues, which is why they do not serve the purpose of treating allergies effectively.
