I think random pill count, just means that they might check your meds, when you are there in the office, for your appointments.
They want you to bring all your meds with you, and so then, if they want to, they can check them to be certain their patients are taking them as prescribed, and not any other way.
It isn't that unusual or terrible, that they ask you to bring them with you, and that they can check the containers, if they want to.
And they are letting patients know beforehand, that they might do that.
Not that big a deal. Patients sometimes do make mistakes in how they are taking them, or they do develop med problems. This way, the doctors can monitor and keep up with any possible problems, if they happen.
They are dispensing lots of serious meds, and paying attention to the results of their scripts. Not terrible.
And worth it, if this doctor is helpful for his patient's medical conditions, and prescribes what Robert needs.
The drug tests, too, might become less often, later on, if the doctor sees they aren't needed, then. The doc might have multiple reasons for doing these things.
Again, it's more important for Robert to have a doctor, now and ongoing.
