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) ].

…Lipid-modifying Agents: lomitapide, lovastatin, simvastatin Phosphodiesterase-5 (PDE-5) Inhibitor: sildenafil when administered as REVATIO ® for the treatment of pulmonary arterial hypertension Sedative/hypnotics: triazolam, orally administered midazolam Coadministration of GENVOYA is contraindicated with drugs that: Are highly dependent on CYP3A for clearance and for which…

Antidepressants: Selective Serotonin Reuptake Inhibitors (SSRIs) e.g., paroxetine Tricyclic Antidepressants (TCAs) e.g., amitriptyline desipramine imipramine nortriptyline bupropion trazodone ↑ SSRIs (except sertraline) ↑ TCAs ↑ trazodone Careful dosage titration of the antidepressant and monitoring for antidepressant response are recommended when coadministered…

Sedative/hypnotic: midazolam (oral) triazolam ↑ midazolam ↑ triazolam Coadministration with triazolam or orally administered midazolam is contraindicated due to potential for serious and/or life-threatening reactions such as prolonged or increased sedation or respiratory depression.

Dosage reduction for midazolam should be considered, especially if more than a single dose of midazolam is administered. buspirone zolpidem With other sedative/hypnotics, dose reduction may be necessary and clinical monitoring is recommended.

Other benzodiazepines: e.g., parenterally administered midazolam clorazepate diazepam estazolam flurazepam ↑ sedatives/hypnotics Triazolam and orally administered midazolam are extensively metabolized by CYP3A.
