He says that on re admission she had relapsed -I don't think he says why. He THEN says the psychosis receded briefly on medication but when it was reduced it returned. It tells me that having tried a lower dose it was found NOT to suppress her symptoms. At this point it clearly was NOT because she'd stopped taking her meds because she wasn't in control of them.
He must have had reasons for feeling "particularly anxious" that she had follow up care and monitoring after she left hospital but it didn't happen.
He stated that prior to her readmission she kept stop taking her medication and missing appointments.
She was on low dose medication prior to her admission and when he returned her to such low dose medication she reverted to thoughts of Freddie as the devil for supplying her with Cocaine etc. That's why he told Colin Freddie was not a good influence on her. He changed her medication to Haloperidol and to injections at that because her history of not taking her medication and prior medication not working when the dosage was reduced.
He said that based on she told her doctor and the observations of her friends her dose was too high and she was oversedated. Our current state of medicine makes clear she wa sindeed overdosed, more than 100MG is not considered safe. Even 100MG is a lot though and they prescribe a countering agent. She wasn't taking that agent and that helps explain why the 100MG still had such a strong effect on her.
Note that after the reduction to 100MG she didn't show any of the signs that she had when she was moved to her low dose medication she had trouble with in the hospital. There is no difference in clinical effectiveness of 100MG and 200MG so that is why it had no effect medically. The side effects of 200MG would obviously be worse but did not go away fully with the reduction because no one was trying to make sure she took the countering agent. I wonder why that is the case because they should have done so to try to improve her daily life.
