The therapeutic effects of the central acetylcholinesterase inhibitor, Tacrine, and/or the anticholinergic, Trimipramine, may be reduced due to antagonism. The interaction may be beneficial when the anticholinergic action is a side effect. Monitor for decreased efficacy of both agents.
|
|
Tacrolimus
|
Additive QTc-prolongation may occur increasing the risk of serious ventricular arrhythmias. Concomitant therapy should be used with caution.
|
|
Telithromycin
|
Additive QTc-prolongation may occur, increasing the risk of serious ventricular arrhythmias. Telithromycin, a strong CYP3A4 inhibitor, may also decrease the metabolism and clearance of Trimipramine, a CYP3A4 substrate. Concomitant therapy should be used with caution.
|
|
Terbinafine
|
Terbinafine may decrease the metabolism and clearance of Trimipramine. Consider alternate therapy or monitor for changes in Trimipramine efficacy and toxicity if Terbinafine is initiated, discontinued or dose changed. Alteration in Trimipramine dose may be required.
|
|
Terbutaline
|
The tricyclic antidepressant, trimipramine, increases the sympathomimetic effect of terbutaline.
|
|
Terfenadine
|
Increased risk of cardiotoxicity and arrhythmias
|
|
Tetrabenazine
|
May cause additive QTc-prolonging effects. Concomitant therapy should be avoided.
|
|
Thiopental
|
The barbiturate, Thiopental, may increase the metabolism and clearance of Trimipramine. Monitor for changes in the therapeutics and adverse effects of Trimipramine if Thiopental is initiated, discontinued or dose changed. Dose adjustments of Trimipramine may be required.
|
|
Thioridazine
|
May cause additive QTc-prolonging effects. Concomitant therapy is contraindicated.
|
|
Thiothixene
|
Additive QTc prolongation may occur. Consider alternate therapy or use caution and monitor for QTc prolongation as this can lead to Torsade de Pointes (TdP).
|
|
Ticlopidine
|
The strong CYP2C19 inhibitor, ticlopidine, may decrease the metabolism and clearance of trimipramine, a CYP2C19 substrate. Consider alternate therapy or monitor for changes in therapeutic and adverse effects of trimipramine if ticlopidine is initiated, discontinued or dose changed.
|
|
Tizanidine
|
Trimipramine may reduce the antihypertensive effect of the alpha2-agonist, Tizandine. Trimipramine may also increase the rebound hypertensive effect of Clonidine. Consider alternate therapy or monitor for changes in the therapeutic and adverse effects of Clonidine if Trimipramine is initiated, discontinued or dose changed. Tizandine should be withdrawn very gradually to reduce the risk of hypertensive crisis.
|
|
Toremifene
|
Additive QTc-prolongation may occur, increasing the risk of serious ventricular arrhythmias. Consider alternate therapy. A thorough risk:benefit assessment is required prior to co-administration.
|
|
Tramadol
|
Tramadol may increase the risk of serotonin syndrome and seizures.
|
|
Tranylcypromine
|
Increased risk of serotonin syndrome. Ensure adequate washout period between therapies to avoid toxicity. Avoid combination or monitor for symptoms of serotonin syndrome and/or hypertensive crisis.
|
|
Trazodone
|
Increased risk of serotonin syndrome. Monitor for symptoms of serotonin syndrome.
|
|
Trimethobenzamide
|
Trimethobenzamide and Trimipramine, two anticholinergics, may cause additive anticholinergic effects and enhance their adverse/toxic effects. Monitor for enhanced anticholinergic effects.
|
|
Triprolidine
|
Triprolidine and Trimipramine, two anticholinergics, may cause additive anticholinergic effects and enhance their adverse/toxic effects. Additive CNS depressant effects may also occur. Monitor for enhanced anticholinergic and CNS depressant effects.
|
|
Trospium
|
Trospium and Trimipramine, two anticholinergics, may cause additive anticholinergic effects and enhanced adverse/toxic effects. Monitor for enhanced anticholinergic effects.
|
|
Venlafaxine
|
Increased risk of serotonin syndrome. Monitor for symptoms of serotonin syndrome.
|
|
Voriconazole
|
Voriconazole, a strong CYP3A4 inhibitor, may increase the serum concentration of trimipramine by decreasing its metabolism. Additive QTc prolongation may also occur. Monitor for changes in the therapeutic and adverse effects of trimipramine if voriconazole is initiated, discontinued or dose changed.
|
|
Vorinostat
|
Additive QTc prolongation may occur. Consider alternate therapy or use caution and monitor for QTc prolongation as this can lead to Torsade de Pointes (TdP).
|
|
Ziprasidone
|
Additive QTc-prolonging effects may increase the risk of severe arrhythmias. Concomitant therapy should be avoided.
|
|
Zolmitriptan
|
Use of two serotonin modulators, such as zolmitriptan and trimipramine, may increase the risk of serotonin syndrome. Consider alternate therapy or monitor for serotonin syndrome during concomitant therapy.
|
|
Zuclopenthixol
|
Additive QTc prolongation may occur. Consider alternate therapy or use caution and monitor for QTc prolongation as this can lead to Torsade de Pointes (TdP).
