ZYRTEC – Allergy Relief, Side Effects & Dosage

 

What Is ZYRTEC?

Allergies are a widespread health condition, especially during spring and summer. For patients who are allergic to pollen and other environmental irritants, allergens can negatively impact quality of life for many months each year. Zyrtec (also available as a generic under the name of Cetirizine) helps relieve allergy symptoms. Available as syrup or tablets, it is an antihistamine manufactured by Pfizer and belongs to a all new modern class of drugs that reduce and eliminate allergic reactions. This antihistamine has been in use since 1996 when it was given the green light by the FDA. It is safe for children as long as it is given under the supervision of a qualified doctor.

It is ideal for many types of allergic reactions including (but not limited to):

– Watery eyes
– Runny nose
– Nasal congestion
– Sneezing
– Itching

How Does ZYRTEC Work? How Long Does ZYRTEC Take To Work? How Long Does ZYRTEC Last?

Zyrtec is an antihistamine which works by blocking histamine receptors from releasing chemicals which lead to a cascade of biological reactions culminating in sneezing, itchiness, watery eyes and sniffling. It specifically targets histamine H1 receptor in the body, switching off the resultant reaction. What’s great about this new drug is the fact that it doesn’t enter the brain from the bloodstream, which in effect lessens drowsiness and motor impairment compared to first generation drugs such as Allegra and Claritin.

A single dose of Zyrtec usually takes only 1 hour to start working, and it keeps allergy symptoms under control for roughly 24 hours.
