Rauvolfia Vomitoria and Midazolam

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

Moderate

CNS DEPRESSANTS

Why this applies to Midazolam

Midazolam falls under CNS DEPRESSANTS — the group Rauvolfia Vomitoria interacts with.

Theoretically, taking Rauvolfia vomitoria might cause additive sedative effects.
Rauvolfia vomitoria has sedative effects in animal research.
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

Here's the simple version: Midazolam (Versed) already does a great job of calming the brain, easing anxiety, and making you drowsy before a procedure. Rauvolfia vomitoria contains reserpine and related alkaloids that, at least in animal studies, also seem to have a sedating, calming effect. Stack the two together and the worry is that those sleepy effects could pile up.

In real terms, that might mean feeling more drowsy, lightheaded, or groggy than expected, with slower breathing or a lower blood pressure being the bigger concerns. I'll be honest with you, this one is theoretical and based on pharmacology and animal data, not strong human studies. Still, since rauvolfia is a potent plant, please tell your doctor or pharmacist you're taking it before any procedure.

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 Rauvolfia Vomitoria

What is Rauvolfia Vomitoria?

  • High blood pressure
  • Anxiety and agitation
  • Sleep problems
  • Mental health symptoms (traditional use)
  • Fever and general ailments

Rauvolfia vomitoria is an African shrub whose root contains powerful alkaloids, including reserpine, that have historically been used for high blood pressure and agitation. Because these compounds can strongly affect blood pressure, mood, and the nervous system, the plant can cause serious side effects and is not a casual supplement. Always talk to a doctor or pharmacist 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.
