title: The use of non-prescription sleep products in the elderly.
abstract: While sleep disorders are common in the elderly, the use of non-prescription products for sleep in this population has not been fully evaluated. The objectives of this project were to assess the use, perceived effectiveness and toxicity of non-prescription sleep products in an ambulatory elderly population.
  
  
  METHODS
  A self-administered 20-question survey was distributed to seniors, aged 60 years or more, during hospital or pharmacy visits.
  
  
  RESULTS
  Of the total respondents (N=176, mean age 74+/-7 years, 59% female), 84 (48%) indicated that they had used one or more therapies for sleep within the past year. These included non-prescription products (50% of therapies), prescription products (17%) and non-drug activities such as walking or drinking milk (34%). For those individuals who had used a non-prescription product in the past year (N=47, 27% of total respondents), the most frequently used products were: dimenhydrinate (21%), acetaminophen (19%), diphenhydramine (15%), alcohol (13%) and herbal products (11%). Most took them at least 1 day per week (79%) and 32% took them daily. These products subjectively improved sleep latency (mean 32 vs 61 minutes, p<0.001), number of nocturnal awakenings (mean 2 vs 3 awakenings, p<0.001) and total hours of sleep (mean 6.6 vs 5.4 hours, p<0.001). Mild side-effects were reported by 35 respondents (75%), the most common being dry mouth (N=22) and daytime drowsiness (N=13). Respondents were taking an average of four (SD+/-3, range 0-10) other medications currently.
  
  
  CONCLUSIONS
  Non-prescription products are widely used by this population of ambulatory elderly for sleep disturbances. Most of the products were not marketed for sleep; however, they were perceived to be efficacious with low toxicity. The potential for drug interaction is high. Further research is warranted to evaluate the safety and effectiveness of non-prescription sleep products in the elderly.
