Haloperidol and Clomipramine Interaction
Drug interaction information between Haloperidol and Clomipramine.
Haloperidol and Clomipramine have a documented minor interaction in FDA labeling.
FDA drug labeling documents a minor-severity interaction between Haloperidol and Clomipramine. Major interactions are generally avoided, moderate ones may need monitoring or a dose adjustment, and minor ones are usually low-risk. This page shows the documented mechanism and guidance. Label-documented interactions are not a complete safety review, so always confirm your own medications with a pharmacist or doctor. Educational information, not medical advice.
How They Interact
Haloperidol can slow down how your body processes clomipramine. This leads to higher amounts of the drug in your blood, which can increase side effects.
What To Do
Your doctor should monitor you closely for side effects. They may need to adjust your clomipramine dosage.
FDA Label Information
The plasma concentration of CMI has been reported to be increased by the concomitant administration of haloperidol; plasma levels of several closely related tricyclic antidepressants have been reported to be increased by the concomitant administration of methylphenidate or hepatic enzyme inhibitors (e.g., cimetidine, fluoxetine) and decreased by the concomitant administration of hepatic enzyme inducers (e.g., barbiturates, phenytoin), and such an effect may be anticipated with CMI as well.

Frequently Asked Questions
Can I take Haloperidol and Clomipramine together?
This is a minor interaction. Your doctor should monitor you closely for side effects. They may need to adjust your clomipramine dosage.
How serious is the interaction between Haloperidol and Clomipramine?
This interaction is classified as "minor" severity by the FDA. Minor interactions are unlikely to cause significant problems but should still be mentioned to your healthcare provider.
Why do Haloperidol and Clomipramine interact?
Haloperidol can slow down how your body processes clomipramine. This leads to higher amounts of the drug in your blood, which can increase side effects.
Understanding the Haloperidol and Clomipramine Interaction
FDA-approved prescribing information for these two drugs flags their combination as a minor-severity interaction. Haloperidol belongs to the Typical Antipsychotic class and Clomipramine belongs to the Tricyclic Antidepressant (TCA) class - two categories that can collide when co-prescribed. The mechanism described in FDA labeling is: Haloperidol can slow down how your body processes clomipramine. Severity tiers matter: major flags generally advise avoidance, moderate flags often require monitoring or dose adjustment, and minor flags may only call for awareness.
Context around a specific patient determines real-world impact. Haloperidol has 14 total documented interactions on file in this dataset, and Clomipramine has 15. Each additional medication compounds the interaction surface, which is why pharmacists run full-profile checks rather than evaluating one pair at a time. FDA-derived guidance for this pair is: Your doctor should monitor you closely for side effects. Timing of doses, renal and hepatic function, age, and other concurrent prescriptions all shape whether a labeled interaction matters clinically.
An interaction flag is not a verdict. A large share of labeled interactions are managed routinely in clinical practice, the fix may be as simple as spacing doses or adding a monitoring test. Others require the prescriber to choose a different medication entirely. This page surfaces FDA-sourced labeling and openFDA data for educational purposes only; it is not medical advice and cannot account for your full clinical picture. Never start, stop, or adjust either Haloperidol or Clomipramine based on a web page, speak with your prescriber or pharmacist before making any change.
