Data on the extent of storage, storage conditions, their current status, disposal methods, among others, were collected through structured interviews and observations. The current study revealed a high prevalence of home medication storage; thus, to lessen or eliminate the negative consequences of storing medications at home, it is necessary to review the medication utilization chain and offer community-based training on proper medication storage and disposal techniques, including establishing take-back programs.
