The lid to a prescription bottle has a digital timer on it. The timer automatically re-sets itself when the prescription bottle is opened, so you know how long it's been since you last took the medication and when to take the next dose.
Each cap costs $3.50.
The caps are expected to be in pharmacies in our area by the end of the year.
For now, you can buy them on the Web at RxTimerCap.com.
