Folks, I TOTALLY agree with Charles T. Meyer, M.D.'s position on this matter. I practiced psychiatric nursing for 10 years and gave many injections to counteract medication reactions from certain antipsychotic drugs. The dyskynesia and dystonias that sometimes result when titrating certain medications up to impact psychiatric symptoms is fully and immediately reversable with a shot in the butt of anticholinergic drugs like akineton, artane, or cogentin. Oh what a blessing if that was so easy in Parkinsons Disease... I'd fill my Surburban up with syringes and travel all over the world tackling Parkies and giving them a "shot in the butt".
