Iloperidone and Paliperidone interaction

Avoid the use of FANAPT in combination with any other drugs that prolong the QT interval [see Warnings and Precautions (5.3) ] .

…prolong QTc including Class 1A (e.g., quinidine, procainamide) or Class III (e.g., amiodarone, sotalol) antiarrhythmic medications, antipsychotic medications (e.g., chlorpromazine, thioridazine), antibiotics (e.g., gatifloxacin, moxifloxacin), or any other class of medications known to prolong the QTc interval (e.g., pentamidine, levomethadyl acetate, methadone).

Seizures Like other antipsychotic drugs, FANAPT may cause seizures.

In the short-term trials, FANAPT was associated with modest levels of prolactin elevation compared to greater prolactin elevations observed with some other antipsychotic agents.

Potential for Cognitive and Motor Impairment FANAPT, like other antipsychotics, may cause somnolence and has the potential to impair judgment, thinking or motor skills.

…combination with other drugs that are known to prolong QTc including Class 1A (e.g., quinidine, procainamide) or Class III (e.g., amiodarone, sotalol) antiarrhythmic medications, antipsychotic medications (e.g., chlorpromazine, thioridazine), antibiotics (e.g., gatifloxacin, moxifloxacin), or any other class of medications known to prolong the QTc interval.

ERZOFRI and other antipsychotic drugs should be used cautiously in patients at risk for aspiration.

Paliperidone has a prolactin-elevating effect similar to that seen with risperidone, a drug that is associated with higher levels of prolactin than other antipsychotic drugs.

Like other antipsychotic drugs, ERZOFRI should be used cautiously in patients with a history of seizures or other conditions that potentially lower the seizure threshold.
