🤧 What Is Cetirizine (Zyrtec)?
Cetirizine is a popular antihistamine primarily used for the relief of allergy symptoms such as sneezing, runny nose, and itchy eyes. Individuals suffering from seasonal allergies or allergic rhinitis frequently turn to Zyrtec due to its effectiveness and relatively mild side effects.
Zyrtec, which contains the active ingredient Cetirizine, belongs to a class of medications known as second-generation antihistamines. This class is commonly used to treat various allergic conditions. Cetirizine works by blocking the action of histamine, a substance in the body that causes allergic symptoms.
