Self-medication of dyspepsia: how appropriate is it?

Abstract

Background: The scope of self-medication is increasing in many countries, and drugs for dyspepsia are a popular group for deregulative activities. This study investigated what kind of upper gastrointestinal symptoms people self-medicate and how appropriate this self-medication is.

Methods: An anonymous questionnaire was give to 50 consecutive customers buying antacids, alginates, or sucralfates in 10 pharmacies in the capital area in Finland in 1995. In half of the pharmacies the questionnaire was returned by mail, and in the other half the questionnaire was filled out at the pharmacy. The response rate was 53% (n = 292).

Results: The commonest reasons for self-medication were heartburn (88%), gastrointestinal pain (31%), and acid regurgitation (32%). Seventy-five per cent of respondents had used dyspepsia drugs for more than a year. The commonest way to self-medicate was to interchange regular and occasional use. Knowledge about the proper use of dyspepsia drugs was poor, and 6% of respondents had symptoms contraindicating self-medication but had not visited a physician during the past year. Patients more than 60 years old were especially at risk of potential inappropriate use.

Conclusions: Over-the-counter (OTC) drugs for dyspepsia are likely to be used improperly. A physician's advice on the use of OTC dyspepsia drugs, in addition to detailed printed information about drug action and proper administration, would be important means to guarantee appropriate use of these drugs.
