Description: Zyrtec (cetirizine dihydrochloride) is a prescription prescription medicine that treats both indoor and outdoor allergy symptoms, as well as chronic hives. In fact, no other allergy prescription medicine of its kind is approved to treat more allergies. During an allergic reaction, tissues in your nose swell in response to contact with the allergen. That swelling produces fluid and mucous. Blood vessels in the eyes also swell, causing redness. Zyrtec helps to shrink swollen nasal tissues and blood vessels and to relieve the symptoms of nasal swelling, congestion, mucous secretion and redness.

Studies show that 1 dose works for a full 24 hours. Zyrtec (cetirizine dihydrochloride) is also great for the whole family. It's the first antihistamine approved to treat indoor allergies in infants 6 months and up. You can order Prescription Zyrtec online by using the order links above.
