What the FDA labels say
From the Haloperidol (Haloperidol Decanoate) label · effective 2025-02-19
An increased risk cannot be excluded for haloperidol decanoate, other antipsychotics, or other patient populations.
As with other antipsychotic agents, it should be noted that haloperidol may be capable of potentiating CNS depressants such as anesthetics, opioids, and alcohol.
From the Loxapine label · effective 2026-01-08
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.
