P - Caution when used during pregnancy
L - Caution when used during lactation

Mizolastine is a once daily, non-sedating antihistamine. It blocks histamine H1 receptors and is commonly fast-acting. It does not prevent the actual release of histamine from mast cells, just prevents it binding to receptors. Side effects can include dry mouth and throat. May also result, in some patients, in dream disturbance or enhancement - this despite not causing drowsiness nor passing into the brain.



Mizolastine, a non-sedating antihistamine, blocks histamine H1-receptors on effector cells of the GI tract, blood vessels and respiratory tract. It also has mast-cell stabilising properties.


Absorbed rapidly from the GI tract (oral); peak plasma concentrations after 1.5 hours.

Protein-binding: 98%.


By glucuronidation (main pathway) or by cytochrome P450 isoenzyme CYP3A4 forming inactive hydroxylated metabolites.


13 hours (elimination half-life).
