benzodiazepines (Klonopin,
Valium), adrenergic antagonists (the beta blocker Atenolol),
and dopamine agonists (Mirapex, Apomorphine).
I had a brief episode of Parkinson-like symptoms from an antipsychotic medicine I was taking when I was younger. The ER gave me a shot of Valium and it reversed the effects, thank goodness. These days they give a shot of Diphenhydramine, I read somewhere. So, the point is, you said Klonopin did not help you, but I wonder if Valium might work a little better.
