Interaction report

German Chamomile and Midazolam

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

Why Are There 2 Interactions?

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

Moderate

CNS DEPRESSANTS

1 of 2

Why this applies to Midazolam

Midazolam falls under CNS DEPRESSANTS — the group German Chamomile interacts with.

Theoretically, German chamomile might have additive effects when used with CNS depressants.
German chamomile has mild sedative effects. Theoretically, concomitant use with drugs with sedative properties can cause additive effects and side effects.
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 explains PharmD, Clinical Pharmacist

Here's the simple version: chamomile has its own mild calming, sleepy effect, and midazolam is a strong sedative used to relax you and make you drowsy before procedures. Put two relaxing things together and they can stack up. With midazolam, that could mean feeling extra groggy, more lightheaded, slower to wake up, or harder to keep alert.

I'll be honest about the evidence, though. This concern is mostly theoretical, based on lab work rather than real patient cases, and a cup of chamomile tea is unlikely to cause trouble. Midazolam is also usually given in a monitored medical setting. Still, since it's a powerful sedative, mention any chamomile tea or supplements to your doctor or pharmacist beforehand so they're aware.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 2

Midazolam also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

Theoretically, German chamomile might inhibit CYP3A4 and increase levels of drugs metabolized by these enzymes.
In vitro evidence shows that German chamomile might inhibit CYP3A4. So far, this interaction has not been reported in humans. However, there might be an increase in the levels of drugs metabolized by CYP3A4 in patients taking German chamomile.
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 short version: your body relies on a liver enzyme called CYP3A4 to break down midazolam (Versed). German chamomile, at least in lab dish studies, seems to slow that enzyme down a little. If it slows the clearance of midazolam, the drug could linger longer and hit harder, meaning more drowsiness, deeper sedation, slower breathing, or feeling groggy and confused for longer than expected.

Now the reassuring part: this is based on test-tube work only, and it has not actually been seen in real people yet. A cup of chamomile tea is unlikely to cause trouble. Still, midazolam is usually given right before a procedure, so be sure to tell your anesthesia team or pharmacist about any chamomile supplements you take.

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 German Chamomile

What is German Chamomile?

German Chamomile
  • Anxiety and stress
  • Sleep and relaxation
  • Digestive upset
  • Skin irritation and inflammation
  • Mouth sores and gum irritation

German chamomile is a widely used herbal remedy taken mainly as a tea for calming, sleep, and digestive complaints. Early research suggests possible benefits for mild anxiety and some skin or digestive issues, but the evidence is limited and most uses are based on tradition rather than strong proof. It is generally well tolerated, but people allergic to ragweed or related plants and those who are pregnant should be cautious.

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.
