As with other antipsychotic drugs, SAPHRIS should be used with caution in patients with a history of seizures or with conditions that potentially lower the seizure threshold.
SAPHRIS and other antipsychotic drugs should be used cautiously in patients at risk for aspiration.

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.
