Pregnenolone and Midazolam

Here is the interaction we found between these two, with the evidence behind it.

Moderate

BENZODIAZEPINES

Why this applies to Midazolam

Midazolam falls under BENZODIAZEPINES — the group Pregnenolone interacts with.

Concomitant use of pregnenolone may reduce the effects of benzodiazepines.
Very preliminary clinical research shows that chronic use of pregnenolone reduces sedative effects of diazepam when compared with chronic use of placebo. This effect may be related to the activity of pregnenolone at GABAA receptors.
Severity Moderate Likelihood Probable Evidence B

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

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

Here's the gist for midazolam (Versed and similar): midazolam is a benzodiazepine that calms the brain by working at receptors called GABA-A. Pregnenolone is a hormone your body turns into other compounds, and some of those act at those very same GABA-A receptors. The concern on file is that taking pregnenolone regularly may dampen the calming, sleepy effect of benzodiazepines, so a dose of midazolam might not relax you or block memory of a procedure as well as expected.

I'll be honest, this comes from very limited human research (and the study looked at diazepam, not midazolam directly), so it's far from certain. Still, since midazolam is often given right before surgery or a procedure, it's worth telling your anesthesia team or doctor that you take pregnenolone. Please don't start or stop anything on your own.

From our pharmacist’s overview on the Midazolam page

“Sedation stacked on sedation is the headline risk with midazolam (Versed, Seizalam, Nayzilam). Midazolam is a benzodiazepine used for sedation and seizure emergencies, and 78 of the 202 interacting ingredients here, beer and wine included, add their own drowsiness, which can slide into dangerously slowed breathing.”

About Pregnenolone

What is Pregnenolone?

Pregnenolone
  • Memory and cognitive support
  • Anxiety and stress
  • Anti-aging
  • Fatigue and low energy
  • Mood support

Pregnenolone is a hormone your body makes naturally and a building block for other hormones like cortisol, DHEA, estrogen, and testosterone. It is sold as a supplement for memory, mood, and anti-aging, but solid human evidence for these uses is very limited. Because it is a hormone, talk with your pharmacist or doctor before using it.

About Midazolam

What Is Midazolam Used For?

Brand names: Versed, Seizalam, Nayzilam

Midazolam is used in several different forms depending on the setting. Injectable midazolam (given by IV or IM shot) is used before and during surgery or procedures — such as endoscopy, cardiac catheterization, or bronchoscopy — to cause sedation, reduce anxiety, and prevent memory of the event. It can also be used to start general anesthesia or to keep heavily sedated, ventilated patients comfortable in a critical care unit. Midazolam HCl oral syrup is used specifically in children for sedation and anxiety relief before procedures or anesthesia induction, in a monitored medical setting only.

Nayzilam nasal spray is indicated for a different purpose: the acute treatment of seizure clusters (also called acute repetitive seizures) in people aged 12 and older who have epilepsy. It is used intermittently — not as a daily seizure medicine — when a cluster of seizures breaks through the person's usual pattern.
