Fourteen insulin-dependent diabetics were asked to use their insulin syringe-needle units three times in succession to determine the efficacy and safety of this practice. The mean duration of time each patient participated in the study was 20.4 weeks, and a total of 2,000 injections were taken. No signs of infections at the injection site were observed. Multiple use of disposable insulin syringe-needle units appears to be safe and cost-beneficial.
