I recently filled a prescription, and experienced firsthand Target's much-touted new prescription labels.

I found relevant information easier and faster to read and understand, and found it easier to pick out the right meds from a crowded cabinet.
Misdosing and mismedicating are common and preventable personal healthcare problem. This is especially true for people with impaired memory or judgement, and with people with multiple caregivers or impared caregivers. There are various time-alarm pill dispensers available for home use, but I don't remember ever seeing studies or observations of their real effectiveness.
