hi. akathisia can be treated with gabapentin, lyrica, benzodiazepines (I think Klonopin and Ativan are preferred, for some reason), and/or propranolol. There's a little bit of data on using remeron for akathisia and also some vitamins, such as massive doses of B6.

Anticholingergics are more commonly prescribed for EPS like tremors and twitches, akinesia, etc. There's some indication that long-term anticholinergic use along with a major tranquilizer increases the risk of tardive dyskinesia.
