About Cetirizine

Cetirizine is an antihistamine tablet which is commonly used to ease symptoms associated with hayfever and other allergies.

It works by interfering with the body’s inflammatory response pathway to lessen symptoms such as itchiness and redness.

Using Cetirizine

Cetirizine is usually taken ONCE daily. If you are a hayfever sufferer, you may find taking the tablet throughout the hayfever season effective in keeping symptoms at bay.

Cetirizine is not associated with causing drowsiness, so is often preferred for regular use over older antihistamines such as Phenergan.


Cetirizine is a widely used and effective antihistamine however every patient can respond differently to medication. If you find Cetirizine is not effective for you, you may want to try Loratadine or another antihistamine.


How many Cetirizine can you take?

You can take ONE 10mg tablet of Cetirizine per day
