Zyrtec contains cetirizine, an antihistamine that relieves allergy symptoms. It works by blocking histamine, a chemical your body releases during an allergic reaction. This blockage prevents the symptoms like sneezing, runny nose, itchy eyes, and hives from occurring.
Understanding Histamine’s Role
Histamine causes blood vessels to dilate, leading to inflammation and the familiar allergy symptoms. Zyrtec prevents histamine from binding to its receptors, effectively stopping the allergic reaction cascade.
Zyrtec’s Action and Benefits
Zyrtec provides 24-hour relief from allergy symptoms for most people. It’s available over-the-counter, making it convenient to manage allergies. Remember to follow dosage instructions on the packaging or consult your doctor or pharmacist for personalized advice.
