An observational study based on data from General Practice Research Database in the UK (in total 197 425 persons) investigated the incidence of ventricular arrhythmias associated with use of non-sedating antihistamines (acrivastine, astemizole, cetirizine, loratadine and terfenadine). Ventricular arrhythmias were four times more common in those using non-sedating antihistamines compared to those with no use. The relative risk in women compared to men was 1.1 (95% CI 0.4-2.9) .
