Antipsychotics (with the exception of quetiapine, clozapine, and pimavanserin) should be avoided in Parkinson’s disease due to the potential worsening of motor symptoms.

Antipsychotics with strong anticholinergic properties should be avoided in patients with obstructive disease of the genitourinary tract.

Antipsychotic use during chemotherapy to prevent vomiting, if used on a short-term basis, may be appropriate.

Unlike the anticonvulsants, the use of lithium is largely restricted to people with significant mood disorders. Lithium withdrawal is poorly characterized other than in terms of relapse. Those who become dependent on it have a new illness episode if lithium is stopped. If happening as the drug dose is lowered this is almost certainly dependence and withdrawal even though the process slips into a full-blown manic or depressive episode.
