Nefazodon ve Vilazodon etkileşimi

Serotonin Syndrome: Increased risk when co-administered with other serotonergic agents, but also when taken alone.

If concomitant use of VIIBRYD with other serotonergic drugs is clinically warranted, inform patients of the increased risk for serotonin syndrome and monitor for symptoms.

The risk is increased with concomitant use of other serotonergic drugs (including triptans, tricyclic antidepressants, fentanyl, meperidine, methadone, lithium, tramadol, tryptophan, buspirone, amphetamines, and St.

CYP3A4 Inhibitors: The VIIBRYD dose should not exceed 20 mg once daily when co-administered with strong CYP3A4 inhibitors ( 2.4 , 7 ).

Strong CYP3A4 Inhibitors (e.g., itraconazole, clarithromycin, voriconazole) The concomitant use of VIIBRYD and strong CYP3A4 inhibitors increased the exposure of vilazodone compared to the use of VIIBRYD alone [see Clinical Pharmacology ( 12.3 )].

Anyone considering the use of nefazodone hydrochloride tablets or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need.

Nefazodone hydrochloride tablets are also contraindicated in patients who have demonstrated hypersensitivity to nefazodone hydrochloride, its inactive ingredients, or other phenylpiperazine antidepressants.

Hyponatremia : Hyponatremia may occur as a result of treatment with SNRIs and SSRIs, including nefazodone.

For a selective serotonin reuptake inhibitor (SSRI), these reactions have included hyperthermia, rigidity, myoclonus, autonomic instability with possible rapid fluctuations of vital signs, and mental status changes that include extreme agitation progressing to delirium and coma.
