Zyrtec is an oral tablet consisting of an antihistamine called cetirizine. This medication is also know internationally as Reactine, and may be purchased in both the brand choice and generic alternative in 5mg, 10mg, and 20mg!

Zyrtec is used to help treat cold or allergy symptoms. These symptoms may include sneezing, itching, watery eyes, or a runny nose. These symptoms can be caused by the common cold, a viral infection, or by allergies, which are caused by allergens. A viral infection is caused by a virus, usually rhinoviruses, although there are many viruses out there that can cause a common cold. As for allergens, they can be anything from dust to pollen to pet dander. Allergens are substances (antigens) that produces an abnormal and vigorous immune response; allergens can be different from person to person, but regardless of what your allergens are, they will cause the immune system to attack it. This is when you will start sneezing, itching, or experiencing other symptoms of allergies.

Additionally, this medication can also be used to help with itching and swelling caused by chronic urticaria, which is a fancy name for hives. Hives can be a result of an allergic reaction, or they may be caused by foods, medications, environmental factors (such as tight clothing or emotional stress), or medical treatments or underlying medical conditions.

Zyrtec (cetirizine) is effective at treating cold and allergy symptoms (as well as hives) because of its power to reduce the effects of histamines in the body, which produce the symptoms followed by the common cold or allergies.
