The methods of prescription-event monitoring have been previously described in detail.5 In brief, the general practitioner writes a prescription which the patient takes to the pharmacist.

While the current generation of lesser sedating antihistamines do not affect the QT interval at normal doses (unlike the previous generation of medicines), there are concerns there may be some effect in overdose.

Examples All children or young people with intentional self-poisoning or significant accidental ingestion Any symptomatic child or young person Any child whose developmental age is inconsistent with accidental poisoning as non-accidental poisoning should be considered.

After three, six, or 12 months, “green form” questionnaires are sent to the general practitioners who wrote the original prescriptions.

These questionnaires seek to determine any event experienced by patients while they were taking the drug and for a period afterwards.

Antihistamines are divided into sedating and lesser sedating (previous called non-sedating) types.Prescription-event monitoring is a form of pharmacovigilance, an exercise which has its legal basis in European Union directives 65/65 and 75/319 and in regulation 2309/93.The method of study (records only research) also complies with the guidelines on the practice of ethics committees in medical research involving human subjects issued by the Royal College of Physicians of London in August 1996.The first generation antihistamines have been associated with side effects, particularly sedation.1 Second generation antihistamines are therefore favoured over the first generation drugs, not because of greatly improved efficacy but because they have fewer side effects, especially sedation.2Although the second generation antihistamines are known to all have similar efficacy,3 the extent of their sedative effects is not well established.To further examine the sedative effects of four commonly prescribed antihistamines—loratadine, cetirizine, fexofenadine, and acrivastine—we analysed the results of four non-interventional observational cohort studies of these drugs performed by the Drug Safety Research Unit.The data collection periods for the four drugs were May to August 1989 for cetirizine and loratadine, May 1989 to September 1990 for acrivastine, and March to August 1997 for fexofenadine.
