Mizolastine is a once daily, non-sedating antihistamine. Sold in the UK on prescriptions as Mizollen. 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.
