Clomipramine and Sertraline Interaction

Drug interaction information between Clomipramine and Sertraline.

Clomipramine and Sertraline have a documented minor interaction in FDA labeling.

FDA drug labeling documents a minor-severity interaction between Clomipramine and Sertraline. 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.

Drug A

Clomipramine

Tricyclic Antidepressant (TCA)

Drug B

Sertraline

Selective Serotonin Reuptake Inhibitor (SSRI)

How They Interact

Sertraline blocks a specific liver protein that breaks down clomipramine. This can cause clomipramine to build up to higher levels in your blood.

What To Do

Your doctor may need to lower your clomipramine dose or watch you closely for side effects.

FDA Label Information

While all the selective serotonin reuptake inhibitors (SSRIs), e.g., fluoxetine, sertraline, paroxetine, and fluvoxamine, inhibit P450 2D6, they may vary in the extent of inhibition.

Frequently Asked Questions

Can I take Clomipramine and Sertraline together?

This is a minor interaction. Your doctor may need to lower your clomipramine dose or watch you closely for side effects.

How serious is the interaction between Clomipramine and Sertraline?

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 Clomipramine and Sertraline interact?

Sertraline blocks a specific liver protein that breaks down clomipramine. This can cause clomipramine to build up to higher levels in your blood.

Understanding the Clomipramine and Sertraline Interaction

FDA-approved prescribing information for these two drugs flags their combination as a minor-severity interaction. Clomipramine belongs to the Tricyclic Antidepressant (TCA) class and Sertraline belongs to the Selective Serotonin Reuptake Inhibitor (SSRI) class - two categories that can collide when co-prescribed. The mechanism described in FDA labeling is: Sertraline blocks a specific liver protein that breaks down 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. Clomipramine has 15 total documented interactions on file in this dataset, and Sertraline has 34. 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 may need to lower your clomipramine dose or watch 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 Clomipramine or Sertraline based on a web page, speak with your prescriber or pharmacist before making any change.
