Drug & supplement interaction

Lactobacillus Crispatus + Etomidate

Etomidate brand name: Amidate.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Lactobacillus Crispatus and Etomidate in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Lactobacillus Crispatus and Etomidate

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Etomidate and Lactobacillus Crispatus in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Etomidate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Etomidate is filed under a single classification — anesthesia. Lactobacillus Crispatus has documented interactions with 1 drug class — the most serious being antibiotic drugs (moderate) — and none of Etomidate’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

No Interaction Found — But Data Suggests Lactobacillus Crispatus and Etomidate May Share a Side Effect

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

Reported for Lactobacillus Crispatus but not commonly for Etomidate: bloating or gas and a higher chance of infection.

Effects for Etomidate come from the ADVERSE REACTIONS section of its FDA label; effects for Lactobacillus Crispatus come from the Natural Medicines adverse-effect record, quoted above.

Everything else you take

See Every Supplement That Interacts With Etomidate

This page covers Lactobacillus Crispatus only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Etomidate page lists 5 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Fever Bark (major), Cannabis (moderate), Cowhage (moderate), Datura Wrightii (moderate) and Delta-9-tetrahydrocannabinol (thc) (moderate).

By severity: 1 major · 4 moderate.

From our pharmacist’s overview on the Etomidate page

“Etomidate is not a pill you take at home. It is an intravenous drug used to put you under quickly for surgery or emergency procedures, and that shapes what this short list of five interacting supplements means.”

About Lactobacillus Crispatus

What is Lactobacillus Crispatus?

  • Vaginal health support
  • Preventing recurrent bacterial vaginosis
  • Reducing recurrent urinary tract infections
  • Yeast infection support
  • General microbiome balance

Lactobacillus crispatus is a 'good' bacterium that naturally dominates a healthy vaginal microbiome and is sold as a probiotic, mainly for vaginal and urinary health. Early research is promising for preventing recurrent bacterial vaginosis and urinary tract infections, but evidence is still limited and product quality varies. Talk with your pharmacist or doctor before using it, especially if you are pregnant or have a weakened immune system.

Lactobacillus crispatus · Lactobacillaceae · Live bacterial cells (probiotic strain) · Oral capsules, vaginal capsules or suppositories, powders, some yogurts and fermented foods

An interaction check asks whether these two react with each other — it does not ask whether Lactobacillus Crispatus is a good idea for someone in your situation. Here is what our Lactobacillus Crispatus record says about it on its own.

Lactobacillus Crispatus: dosing

There is no single standardized dose of Lactobacillus crispatus. Probiotic doses are usually measured in colony-forming units (CFU), and the right amount can vary by product and by why you are using it.The best approach is to follow the directions on the product label for the specific oral or vaginal product you have chosen.

About Etomidate

What Is Etomidate Used For?

Brand name: Amidate

Etomidate — available as Amidate and under the generic name Etomidate — is given by intravenous (IV) injection to induce general anesthesia before surgery or other procedures. It brings on unconsciousness rapidly, usually within about one minute.

Amidate and etomidate injection products are also used to supplement weaker anesthetic agents, such as nitrous oxide in oxygen, during short operative procedures — for example, dilation and curettage (D&C) or cervical conization. This supplemental use is supported only for adult patients in short procedures; it is not recommended for longer procedures or for pediatric patients.

Taking Lactobacillus Crispatus and Etomidate Together: Common Questions

Is it safe to take Lactobacillus Crispatus with Etomidate?
We do not list a known interaction between Lactobacillus Crispatus and Etomidate. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Lactobacillus Crispatus and Etomidate have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Lactobacillus Crispatus and Etomidate combination checked?
Interactions in our licensed database are recorded against drug classes. Etomidate is filed under 1 classification, and Lactobacillus Crispatus has documented interactions with 1 drug class — none of Etomidate's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Lactobacillus Crispatus interact with any other medications?
Yes. Lactobacillus Crispatus has 182 documented drug interactions in our database — Etomidate is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Etomidate interact with any supplements?
Yes. Etomidate has documented interactions with 5 supplements in our database — Lactobacillus Crispatus is not one of them. The Etomidate interaction page linked on this page lists every one, ranked by severity.
