What type of medications are used to alleviate allergy symptoms like runny nose and itchy eyes?

Antihistamines are specifically designed to relieve symptoms caused by allergies, such as a runny nose and itchy eyes. They work by blocking the action of histamine, a substance in the body that triggers allergy symptoms during an allergic reaction. By inhibiting histamine's effect, antihistamines help reduce inflammation and the effects that lead to discomfort associated with allergies, making them the most appropriate choice for alleviating such symptoms.

Other options like immunizations, bronchodilators, and antispasmodics serve different purposes. Immunizations are primarily preventive measures against infectious diseases. Bronchodilators are used to open airways and are typically prescribed for conditions like asthma. Antispasmodics are aimed at reducing spasms in smooth muscles and may not directly address allergy symptoms.
