For which condition is Zyrtec typically used?

Zyrtec, also known as cetirizine, is an antihistamine that is primarily used to relieve allergy symptoms. These symptoms can include sneezing, runny or itchy nose, and itchy or watery eyes. Zyrtec works by blocking the action of histamine, a substance in the body that causes allergic symptoms.

While it may help alleviate some mild cold symptoms due to its ability to reduce nasal congestion and sneezing, it is specifically indicated for allergies, making it the most appropriate choice in this context. Zyrtec is not indicated for treating infections or headaches, which further solidifies its designation as a medication for allergies.
