The dosage is not insignificant. It is dangerous to cut down Haloperidol drastically and without monitoring the patient, preferably in a hospital setting.
That is what is recommended, cut down by 10 mg at a time, then monitor for a week, then cut down another 10 mg, monitor and so on.
Besides, Dr. Angeloglou was angry at her assisting Dr. Wilkinson for cutting down the dose - if it didn´t mean anything, why was she angry?
Because of a turf war or they were such lousy doctors they didn't even realize 200MG was an absurd amount.
The truth is that after the cut in half she was still taking the highest safe dosage. She was given way too much of a dosage. The reason for cutting in small increments is to figure out the minimal dosage necessary for maintenance. You are not supposed to start someone at more than 100MG though and then to work down from there you start at between 50 and 100 and work down. They stopped manufacturing Haldol decanoate in doses higher than 100MG because greater doses provide no better performance simply bad side effects. They didn't know at the time of the murders there was zero added performance but still had reason to know of the oversedating caused by such large doses.
It is dishonest to keep suggesting the medication would stop working because of the reduction, there is no effective difference between 100MG and 200MG. There is a big difference in that someone taking 200MG would have a hard time living a normal life they would be over sedated. Even at 100MG she was oversedated though in part that was because she was not taking a counter agent. She could have been taking something that gave her energy but she never refilled the prescription. So despite the cut she was still overly tired, vacant, communication problems and the rest...
She exhibited no signs of relapsing after the dosage reduction and no signs of withdrawal.
This whole issue is a red herring of sorts because the evidence that proves Sheila didn't kill herself and didn't do anything to anyone else. Even if she had been completely taken off her medication and thus was a ticking time bomb for a new episode eventually that still would not in any way counter the evidence that she could not have killed herself and didn't do anything to anyone else.
