title: A survey of self-medication practices and perceived effectiveness of glucosamine products among older adults.
abstract: OBJECTIVE
  The purpose of this study was to investigate the decision-making and self-treatment practices of older users of glucosamine products, namely (1) how do older adults decide to use glucosamine products? (2) what influences their choice? (3) how do they manage their glucosamine treatment? and (4) what is their perception of the effectiveness, side effects, and costs of glucosamine products?
  
  
  METHODS
  A descriptive, exploratory study using a questionnaire survey.
  
  
  METHODS
  Province-wide. Invitations to participate were extended to all people living in a Canadian province who used/had used glucosamine products.
  
  
  RESULTS
  Advice from friends was a major factor in the decision to take glucosamine. Cost was a major factor influencing the type and brand name of the product used. Ninety-two percent managed their own treatment. The majority (88%) used glucosamine regularly; only one-third took the recommended daily dose. Sixty-seven percent perceived the product to be helpful in relieving symptoms.
  
  
  CONCLUSIONS
  Public education and further research is needed regarding the use of glucosamine products.
