Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, drug fever, and primary central nervous system (CNS) pathology.
Loxapine, like other antipsychotics, may impair mental and/or physical abilities, especially during the first few days of therapy.
Therefore, ambulatory patients should be warned about activities requiring alertness (e.g., operating vehicles or machinery) and about concomitant use of alcohol and other CNS depressants.
From the Prochlorperazine (PROCHLORPERAZINE MALEATE) label · effective 2025-07-09
To lessen the likelihood of adverse reactions related to cumulative drug effect, patients with a history of long-term therapy with prochlorperazine and/or other antipsychotics should be evaluated periodically to decide whether the maintenance dosage could be lowered, or drug therapy discontinued.
