How it works

From the US prescribing label for the same active substance (CETIRIZINE HYDROCHLORIDE). It describes the substance, not this exact product.

Mechanism of Actions Cetirizine, a human metabolite of hydroxyzine, is an antihistamine; its principal effects are mediated via selective inhibition of peripheral H 1 receptors.

The antihistaminic activity of cetirizine has been clearly documented in a variety of animal and human models.

The shape is a standard model drawn from the two times above, not a measurement. How fast a medicine acts and wears off also depends on the dose, the form and the person.
How the body breaks it down

Cetirizine is metabolized to a limited extent by oxidative O-dealkylation to a metabolite with negligible antihistaminic activity.

With food

Food had no effect on the extent of cetirizine exposure (AUC) but T max was delayed by 1.7 hours and C max was decreased by 23% in the presence of food.
