Drug Interactions


Effects may be increased.


May increase effects of clomipramine.


Cisapride is contraindicated in patients receiving tricyclic antidepressants.


May result in hypertensive crisis.

CNS depressants

Depressant effects may be additive.

Drugs highly protein bound (eg, digoxin, warfarin)

Clomipramine may displace these agents from their plasma protein-binding sites, resulting in transient increases in plasma concentrations.


Antihypertensive effects may be decreased.

Hepatic enzyme inducers (eg, barbiturates, hydantoins, rifamycins)

May decrease effects of clomipramine.

Hepatic enzyme inhibitors (cimetidine, fluoxetine, haloperidol, oral contraceptives, phenothiazine antipsychotics)

May increase effects of clomipramine.


Sweating, convulsions, and death may occur. Coadministration or use within 14 days before or after treatment with an MAOI is contraindicated.


Levels may be elevated by clomipramine, increasing the pharmacologic and adverse effects.

Quinolones (gatifloxacin, levofloxacin, moxifloxacin, sparfloxacin)

The risk of life-threatening cardiac arrhythmias may be increased.

Laboratory Test Interactions

None well documented.
