Milk Thistle and olanzapine

I take olanzapine 10mg. And I take benztropine for side effects. I feel tired now. So I will take milk thistle. So I want to know milk thistle affect any side-effects for olanzapine. Dose Milk thistle affect olanzapine less effective ?

If Olanzapine is broken down by the liver, then yes. (I don’t know if it is)
