The use of RALDESY Should be avoided in patients with known QT prolongation or in combination with other drugs that are inhibitors of CYP3A4 (e.g., itraconazole, clarithromycin, voriconazole), or known to prolong QT interval including Class 1A antiarrhythmics (e.g., quinidine, procainamide) or Class 3 antiarrhythmics (e.g., amiodarone, sotalol), certain antipsychotic…

CYP3A4 Inhibitors: Consider RALDESY dose reduction based on tolerability ( 2.5 , 7 ).

Strong CYP3A4 Inhibitors Clinical Impact: The concomitant use of RALDESY and strong CYP3A4 inhibitors increased the exposure of trazodone compared to the use of RALDESY alone.

Intervention: If RALDESY is used with a potent CYP3A4 inhibitor, the risk of adverse reactions, including cardiac arrhythmias, may be increased and a lower dose of RALDESY should be considered [see Dosage and Administration (2.5) , Warnings and Precautions (5.3) ].
