Main outcome measure: Reporting of sedation or drowsiness.

Results: The odds ratios (adjusted for age and sex) for the incidence of sedation were 0.63 (95% confidence interval 0.36 to 1.11; P=0.1) for fexofenadine; 2.79 (1.69 to 4.58; P Antihistamines are often used to treat the symptoms of allergies such as seasonal and perennial allergic rhinitis and urticaria.

As well as tablets, antihistamines are available as injections, elixirs, and creams.

An injection can be given in case of severe allergic reaction (although in such cases, adrenaline (epinephrine) may be more appropriate and can be life-saving).

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.

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.

All reported pregnancies are followed up to determine the outcome and the cause of all deaths are established.

Both the exposure (prescription) and the outcome (event) data are computerised for analysis.

New antihistamines include rupatidine, which is similar to loratidine. Terfenadine (Teldane™) and astemisole (Hismanal™) have been withdrawn from the New Zealand market.
