Cetirizine is an anti-allergy medication that's for relieving symptoms related to allergy such as itching, watery eyes and running nose. It works by blocking histamine that your body makes during an allergic reaction. 

 

It is administered in the form of an oral tablet and suspension. There is no intravenous preparation.

 

Compared to older common antihistaminics, cetirizine has the least sedative effect i.e. less sleep and drowsiness. It's also a one-a-day dose and can be safely given to most age groups. It has the least drug-to-drug interactions and can be used safely along with other drugs.

 

Side effects include: drowsiness, tiredness and dry mouth may occur. In children, it may cause stomach pain.
