An impervious housing having a compartment for a pharmaceutical product and an independent compartment for containing circuitry that senses and records when a patient administers the pharmaceutical contained in the first compartment. The circuit includes a clock which produces a pulse each hour and an addressable memory coupled to the clock so that the address is changed each hour. Sensors for determining when the cap is removed from the first compartment and when the housing is inverted, the output of the sensors being coupled to a register at the input of the circuitry so that if a patient has administered the pharmaceutical since the last clock pulse, a binary signal indicative of that fact will be transferred from the register to the memory upon occurrence of a succeeding clock pulse.
