Drug & supplement interaction

Carob + Esketamine

Esketamine brand name: Spravato.

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 Carob and Esketamine 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.

Carob and Esketamine

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 Esketamine and Carob 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.

Carob safety at a glance

Carob overall Generally safe Carob is widely consumed as a food and is generally considered safe in normal food amounts.
Pregnancy Use caution Food amounts are likely fine, but concentrated supplement doses are not well studied, so use caution.
Breastfeeding Use caution Food amounts are likely fine, but there is little safety data on medicinal or supplement doses.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Esketamine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Esketamine is filed under 2 classifications — tricyclic antidepressants (tcas), antidepressant drugs. Carob has documented interactions with 1 drug class — the most serious being oral drugs (minor) — and none of Esketamine’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 Carob and Esketamine May Share Several of the Same Side Effects

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.

  • Tiredness / Vomiting Additional detail

    Carob

    “A five month-old child who was allergic to an anti-regurgitation milk formula containing carob gum experienced urticaria, rash, and explosive vomiting within 30 minutes of administration of the formula. In a separate case, an 11-week-old infant with Down syndrome presented with persistent vomiting, watery diarrhea, and lethargy requiring IV hydration.”

    Esketamine

    Listed in the ADVERSE REACTIONS section of the FDA label for Esketamine. Read the label on DailyMed ›

Reported for Carob but not commonly for Esketamine: chest pain, hives, diarrhea and a stuffy or runny nose.

Effects for Esketamine come from the ADVERSE REACTIONS section of its FDA label; effects for Carob come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 17,728 voluntary FDA FAERS reports for Esketamine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

See Every Supplement That Interacts With Esketamine

This page covers Carob only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Esketamine page lists 11 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Scopolia (major), Cowhage (moderate), Dhea (moderate), Griffonia Simplicifolia (moderate) and Indian Snakeroot (moderate).

By severity: 1 major · 6 moderate · 4 minor.

From our pharmacist’s overview on the Esketamine page

“Esketamine (Spravato) is the nasal spray for depression that hasn't responded to standard treatment, and its supplement list deserves genuine respect. Scopolia carries the only major rating and is the entry to understand before any other; pairing it with the medication can raise the risk of anticholinergic effects, meaning dry mouth, b…”

About Carob

What is Carob?

Carob
  • Diarrhea (especially in children)
  • Cocoa/chocolate substitute
  • Digestive upset
  • Acid reflux/heartburn
  • Source of dietary fiber

Carob is a Mediterranean tree whose pods are widely used as a caffeine-free, naturally sweet cocoa alternative and as a thickener (carob gum). It is mostly eaten as a food and is generally well tolerated, and carob pod preparations have some traditional and limited research use for diarrhea, but evidence for most medicinal claims is limited. Check with your pharmacist or doctor before using it as a treatment, especially for infants or children.

Ceratonia siliqua · Fabaceae · Pods (fruit), seeds, and seed gum · Carob powder (flour), carob gum (locust bean gum), carob syrup, chips, capsules

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

Carob: dosing

There is no official, standardized medicinal dose for carob. It is most often used as a food ingredient rather than a measured supplement.If you use a carob product such as a powder, syrup, or capsule, follow the directions on the product label.

About Esketamine Nasal Spray

What Is Esketamine Nasal Spray Used For?

Brand name: Spravato

Spravato nasal spray is approved for two uses in adults. First, it treats treatment-resistant depression (TRD) — depression that has not responded to other antidepressants — either on its own or alongside an oral antidepressant. Second, it treats depressive symptoms in adults with major depressive disorder (MDD) who have acute suicidal ideation or behavior, always used together with an oral antidepressant in this case.

Important limits: Spravato has not been shown to prevent suicide or reduce suicidal thoughts or behavior on its own. It is not a replacement for hospitalization if that is clinically needed, and it is not approved as an anesthetic.

Most-Reported Side Effects for Esketamine

From FAERS, the FDA’s public side-effect reporting system (17,728 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Dissociation 3,733 reports
Sedation 2,706 reports

Taking Carob and Esketamine Together: Common Questions

Is it safe to take Carob with Esketamine?
We do not list a known interaction between Carob and Esketamine. 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 Carob and Esketamine have any of the same side effects?
Yes — our sources link each of them separately to 2 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 Carob and Esketamine combination checked?
Interactions in our licensed database are recorded against drug classes. Esketamine is filed under 2 classifications, and Carob has documented interactions with 1 drug class — none of Esketamine'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 Carob interact with any other medications?
Yes. Carob has 2,022 documented drug interactions in our database — Esketamine 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 Esketamine interact with any supplements?
Yes. Esketamine has documented interactions with 11 supplements in our database — Carob is not one of them. The Esketamine interaction page linked on this page lists every one, ranked by severity.
