Whats the best way to treat antipsychotics, such as risperidone, anticholinergic effects?

Answer: There are a few medications to try to control the side effects off the antipsychotic medications. Cogentin (benztropine) works well and is well tolerated

Extrapyramidol: I guess that this is what you're referring to, rather than "anticholinergic." But there is no single best way. There are a number of medicines that can be taken, including some anticholinergic medicines. But it is an individualized decision.
