Abstract

A programmed clock for signalling a person the times that dosages of medication are to be taken in compliance with a medication regimen. A record producing apparatus is provided for producing a record of the person'"'"'s compliance with the medication regimen. A control program, including a programmed timer, determines the time that dosages of medication are to be taken from a plurality of compartments. The program activates the record producing apparatus to provide a message that dosages of medication have been missed and that further actions should be taken in response to the missing of successive dosages of medication. The control program also activates the record producing apparatus to provide the person with information useful for correlating the actual chemical or brand name identification of the medication with the compartment storing the medication and other information regarding the medication regimen to be taken prior to activation of the timing function. The control program permits dosages of medication to be taken ahead of schedule while at the same time to disabling the alarm for the scheduled dosage which has been taken ahead of time. The control program also monitors the external power source to provide a message of when the external power source has been cut off and subsequently resumes and to identify any dosages of medication which were missed during the interval that the external power source was disconnected. The control program causes the record producing apparatus to print out prior to the scheduled time when scheduled appointments with health care personnel are to occur. The control program also causes the record producing apparatus to print out prior to taking of the last dosage that it is time to consider the refilling of refillable prescriptions.
