Disposal of prescription drugs by parents of middle and high school students.

To determine how parents dispose of unused prescription medications and correlates of disposal, we recruited 3,043 parents of adolescents to complete a survey. Multivariate and multinomial logistic regression was conducted to examine correlates of disposal of prescription medication. Only 17.8% of parents in a household prescribed a controlled medication in the past year disposed of unused medications. Of those, 36.7% used organized disposal (e.g., take-back event or drop box) and 63.3% disposed of medications at home. Organized disposal was associated with awareness of disposal opportunities. Increasing awareness of organized disposal opportunities is a promising mechanism to increase their use by parents.
