General practitioners' views on the over-the-counter availability of H2-antagonists

In recent years there has been a trend towards increasing the number of drugs that are available over the counter (OTC) without prescription. Simultaneously, community pharmacists have been encouraged to develop and extend their role. General practitioners (GPs) have been shown to have some reservations about these developments. A group of drugs widely used in general practice, the H2-antagonists, have recently become available OTC.

To examine GPs' attitudes towards community pharmacists dispensing H2-antagonists over the counter (OTC) without prescription.

Postal questionnaire to a sample of GPs from inner and outer London, Surrey, Kent, Hampshire, Northumberland, Newcastle upon Tyne and Leicestershire.

Of 850 questionnaires sent, 515 were returned, an overall response rate of 60.5%. Fifty four per cent of respondents agreed that cimetidine should be available over the counter for dyspepsia in adults under 45 years not responsive to antacids. Ninety per cent of respondents were aware that H2-antagonists had been deregulated. Most general practitioners learned about the deregulation from professional journals. Very few GPs stated they had changed their prescribing practice since H2-antagonists became available OTC. The high cost to the patient of the OTC product was the most frequently mentioned reason why respondents did not encourage their patients to switch from prescription to OTC H2-antagonists. Worries and concerns regarding the OTC availability of H2-antagonists included masking serious conditions, missed diagnosis, loss of control by the GP and the potential for inappropriate use by patients.

Since 1990, there has been a large increase in GPs support for the OTC availability of cimetidine. However, according to their stated behaviour, the reclassification of H2-antagonists does not seem to have changed GPs' prescribing practice, and few appear to be recommending that their patients buy them over the counter.
