If the dispensing device is “locked” against the user and you want to enforce dosing you don’t need any crypto keys. Just make the device have an internal clock and dispense a dose every X hours.
In the general case, the device is externally controlled and then people who have control can do whatever they want with it. I’m still not seeing a particular need for a crypto key.

Forever? What if you want to change the dosage.

So that only the person who’s supposed to control it can control it. You don’t want someone altering it with their laptop just because they have bluetooth.
Edit:
Somehow I was thinking of implanting something that dispensed drugs. Just dispensing pills would make most of that pointless. Why worry about someone breaking it with a laptop if they can break it with a hammer? I suppose it might work if you somehow build the thing like a safe.
