Serious Warnings
Antidepressants may increase the risk of suicidal thoughts or actions in children, teens, and young adults. Watch closely for worsening mood or unusual behavior. Clomipramine is only approved for OCD in children.
Known Drug Interactions
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.
Mechanism: Sertraline blocks a specific liver protein that breaks down clomipramine. This can cause clomipramine to build up to higher levels in your blood.
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. While all the selective serotonin reuptake inhibitors (SSRIs), e.g., fluoxetine, sertraline,...
Mechanism: Fluoxetine slows down the liver's process for clearing clomipramine from your body. This can lead to higher and potentially unsafe levels of clomipramine.
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.
Mechanism: Methylphenidate can interfere with how your body gets rid of clomipramine. This causes the amount of clomipramine in your system to increase.
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.
Mechanism: Paroxetine blocks the liver enzyme responsible for breaking down clomipramine. This makes clomipramine stay in your body longer and reach higher levels.
Several tricyclic antidepressants have been reported to block the pharmacologic effects of guanethidine, clonidine, or similar agents, and such an effect may be anticipated with CMI because of its structural similarity to other tricyclic antidepressants.
Mechanism: Clomipramine can interfere with how clonidine works in your body. This prevents clonidine from effectively lowering your blood pressure.

What the FDA Data Shows for clomipramine
The FDA label for clomipramine (sold under brand names such as Anafranil) classifies it as a prescription-only medication in the Tricyclic Antidepressant (TCA) class. Clomipramine treats obsessive-compulsive disorder (OCD). Official labeling lists 17 commonly reported side effects, including Dry mouth, Constipation, Nausea.
Post-market surveillance from the FDA Adverse Event Reporting System (FAERS) captures real-world experience. For this drug, FAERS contains 4,403 voluntary reports. The database also lists 15 documented drug interactions derived from FDA labeling, with the top-flagged interaction rated minor severity. NADAC pricing from CMS shows a generic unit cost of $0.28.
Report counts do not establish causation, a FAERS entry documents a temporal association, not proof that the drug produced the outcome. Widely prescribed medications naturally accumulate more reports than niche therapies, so raw totals must be interpreted alongside total exposure. Shortage status, recall history, and patent information are separate source-record fields. This page is a public FDA/CMS registry and does not provide medical, treatment, substitution, or medication-change directions.
