Interação entre Duloxetina e Nefazodona

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

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

Other Serotonergic Drugs Prevention or Management Monitor for symptoms of serotonin syndrome when Duloxetine Delayed-Release Capsules is used concomitantly with other drugs that may affect the serotonergic neurotransmitter systems.

Mechanism and Clinical Effect(s) Concomitant use of Duloxetine Delayed-Release Capsules with other serotonergic drugs increases the risk of serotonin syndrome.

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

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.

…nefazodone and its major metabolites are not altered in these “poor metabolizers.” Plasma concentrations of one minor metabolite (mCPP) are increased in this population; the adjustment of nefazodone dosage is not required when administered to “poor metabolizers.” Nefazodone and its metabolites have been shown in vitro to be extremely weak inhibitors of CYP2D6.

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