Interaction report

Dhea and Amitriptyline, Chlordiazepoxide

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Dhea interacts with whole categories of medication. Amitriptyline, Chlordiazepoxide falls into 2 of those categories, so it can interact with Dhea in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

ANTIDEPRESSANT DRUGS

1 of 2

Why this applies to Amitriptyline, Chlordiazepoxide

Amitriptyline, Chlordiazepoxide falls under ANTIDEPRESSANT DRUGS — the group Dhea interacts with.

Theoretically, DHEA might increase the risk of psychiatric adverse events when used with antidepressants.
In a human case report, the use of a selective serotonin reuptake inhibitor (SSRI) with DHEA caused a manic episode. Concern for this interaction may be greater in younger individuals with higher baseline DHEA levels.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Limbitrol DS combines amitriptyline (an older antidepressant) with chlordiazepoxide (a calming benzodiazepine). The concern here isn't about DHEA blocking or speeding up how your body clears these medicines. Instead, because DHEA acts as a hormone and can nudge brain chemistry, there's a theoretical worry that pairing it with an antidepressant could tip mood in the wrong direction, such as triggering an unusually elevated, agitated, or manic mood.

Keep in mind this is weak evidence, based mostly on lab work plus a single case report involving a different type of antidepressant. It's something to be aware of, not panic over. If you take Limbitrol and are considering DHEA, especially if you're younger, please check with your pharmacist or doctor first and watch for unusual restlessness, racing thoughts, or trouble sleeping.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 2

Amitriptyline, Chlordiazepoxide also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

Theoretically, DHEA might increase the levels of drugs metabolized by CYP3A4.
Some preliminary evidence shows that DHEA may inhibit CYP3A4; however, the clinical significance of this potential interaction is not known.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Limbitrol combines amitriptyline (an older antidepressant) with chlordiazepoxide (a benzodiazepine for anxiety). Both rely on a liver enzyme called CYP3A4 to be broken down. Some early, limited lab data suggests DHEA might slow that enzyme down a bit. If that happened, these medicines could clear a little slower and build up in your body.

In real terms, that might mean stronger drowsiness, dizziness, dry mouth, constipation, or feeling more sedated than usual. I want to be honest though: this is theoretical and based on very weak, anecdotal evidence, so we really don't know if it matters in everyday use. Since this combo already makes many people sleepy, it's worth a quick chat with your pharmacist or doctor before adding DHEA.

From our pharmacist’s overview on the Amitriptyline, Chlordiazepoxide page

“Alcohol is the first thing to know about here. Beer and wine both carry major, well-documented interactions with Amitriptyline and Chlordiazepoxide (Limbitrol DS), because both drugs already slow the central nervous system, and anything sedating layered on top can deepen ordinary drowsiness into something dangerous.”

About Dhea

What is Dhea?

Dhea
  • Anti-aging and low DHEA levels
  • Mood and depression
  • Vaginal dryness and sexual health
  • Fertility support
  • Muscle mass and athletic performance
  • Adrenal insufficiency

DHEA is a natural hormone that the body makes and that declines with age, and it is sold as a supplement claiming many benefits. The evidence is mixed and limited for most uses, and because it acts as a hormone it can cause real side effects. Talk to a pharmacist or doctor before using it, especially if you have a hormone-sensitive condition.
