During an emergency room shift, you encounter a disheveled looking man claiming that he is President Kennedy’s love child and the FBI is out to get him. He also endorses that the aliens are responsible for his fathers death and that the aliens implanted a chip in his head to constantly speak to him. Upon review of his medical record, you notice that he made a previous visit to the ER for a similar episode about 8 months ago. Besides his eccentric demeanor and disorganized speech, his vitals and physical exam are all within in normal range. No illicit substances were identified following a urinary toxicology screening. What type of medication would be best long-term for our patient?
