Is there a drug interaction between sertraline (SSRI) and Librium (chlordiazepoxide, benzodiazepine)?

From the Guidelines

There is a potential drug interaction between sertraline and Librium, as they can cause increased central nervous system depression when taken together, leading to enhanced sedation, drowsiness, impaired coordination, and decreased alertness. This interaction is not explicitly mentioned in the provided evidence, but it is known that benzodiazepines like Librium can interact with various medications, including SSRIs like sertraline, to increase the risk of CNS depression 1. The mechanism of this interaction is not fully explained in the provided evidence, but it is likely related to the inhibition of the CYP450 enzyme system in the liver, which can increase benzodiazepine blood levels and intensify their effects.

Some key points to consider when prescribing sertraline and Librium together include:

• Monitoring patients for excessive sedation and advising them to avoid activities requiring mental alertness until they know how this combination affects them
• Avoiding alcohol, which can further increase CNS depression
• Adjusting dosages, particularly of the benzodiazepine, if both medications are deemed necessary
• Educating patients to report any unusual drowsiness, confusion, or coordination problems to their healthcare provider immediately

It is essential to note that the provided evidence does not specifically address the interaction between sertraline and Librium, but it does discuss the potential for drug interactions with SSRIs and benzodiazepines in general 1. Therefore, healthcare providers should exercise caution when prescribing these medications together and closely monitor patients for any adverse effects.

The potential risks associated with this combination include:

• Increased risk of suicidal thinking and behavior, particularly in children and adolescents 1
• Behavioral activation/agitation, which can occur early in treatment or with dose increases 1
• Serotonin syndrome, a potentially life-threatening condition caused by elevated brain serotonin levels 1
• Other adverse effects, such as dry mouth, nausea, diarrhea, and insomnia, which are common with SSRI use 1

From the FDA Drug Label

In a study comparing the disposition of intravenously administered diazepam before and after 21 days of dosing with either sertraline (50 to 200 mg/day escalating dose) or placebo, there was a 32% decrease relative to baseline in diazepam clearance for the sertraline group compared to a 19% decrease relative to baseline for the placebo group (p<0. 03). The risk of using sertraline in combination with other CNS active drugs has not been systematically evaluated Consequently, caution is advised if the concomitant administration of sertraline and such drugs is required

The drug interaction between sertraline and Librium (chlordiazepoxide, a benzodiazepine) is not directly addressed in the label, but there is information about the interaction between sertraline and diazepam, another benzodiazepine. Caution is advised when using sertraline with other CNS active drugs, including benzodiazepines like Librium. Key points to consider:

• The label does not provide direct information about the interaction between sertraline and Librium.
• The interaction between sertraline and diazepam suggests a potential decrease in diazepam clearance.
• Caution is advised when using sertraline with other CNS active drugs, including benzodiazepines like Librium 2.

From the Research

Drug Interaction Between Sertraline and Librium

• The interaction between sertraline (an SSRI) and Librium (chlordiazepoxide, a benzodiazepine) is not directly addressed in the provided studies.
• However, a study 3 notes that no clinically relevant effects were noted in the interaction studies with diazepam, which is also a benzodiazepine like Librium.
• This suggests that sertraline may not have a significant interaction with benzodiazepines like Librium, but it is essential to exercise caution when combining these medications.
• Another study 4 reports a serious drug interaction between sertraline and phenelzine (a monoamine oxidase inhibitor), resulting in serotonin syndrome.
• While this study does not involve Librium, it highlights the importance of monitoring for potential interactions when combining sertraline with other central nervous system depressants.
• Other studies 5, 6, 7 discuss the risk of serotonin syndrome with various drug combinations involving sertraline, but do not specifically address the interaction with Librium.
• In general, it is crucial to carefully evaluate the potential risks and benefits of combining sertraline with other medications, including benzodiazepines like Librium, and to monitor patients closely for any adverse effects.
