Drug & supplement interaction

Octopamine + Esomeprazole

Esomeprazole brand name: Nexium.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Octopamine and Esomeprazole 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 label for Esomeprazole states a food rule worth keeping to, and 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.

Octopamine and Esomeprazole

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 Esomeprazole and Octopamine 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 Esomeprazole

Interactions in our licensed database are recorded against drug classes, not just single drug names. Esomeprazole is filed under 6 classifications — including proton pump inhibitors (ppis), cytochrome p450 2c19 (cyp2c19) inhibitors, cytochrome p450 1a2 (cyp1a2) inducers. Octopamine has documented interactions with 3 drug classes — the most serious being antihypertensive drugs (moderate), monoamine oxidase inhibitors (maois) (moderate) and stimulant drugs (minor) — and none of Esomeprazole’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 Octopamine and Esomeprazole 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. One of them is worth acting on rather than waiting out — marked below.

  • Chest pain Worth acting on Additional detail

    Octopamine

    “Octopamine is commonly used as a stimulant. Due to its chemical similarities to synephrine, a stimulant with the potential to cause severe cardiovascular effects, Health Canada has set the maximum daily dose of octopamine at 50 mg.”

Reported for Octopamine but not commonly for Esomeprazole: a heart attack and dehydration.

Effects for Esomeprazole come from the ADVERSE REACTIONS section of its FDA label; effects for Octopamine come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 235,235 voluntary FDA FAERS reports for Esomeprazole 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.

How to take them

Some Esomeprazole Products Have a Food Rule — Octopamine Should Not Break It

At least one FDA label for a product containing Esomeprazole says to take it on an empty stomach. Most supplements — Octopamine included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Esomeprazole on its own and move Octopamine to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Esomeprazole products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Table 2: Recommended Dosage of Esomeprazole Magnesium Delayed-Release Capsules in Pediatric Patients by Indication Indication Patient Age Recommended Dosage Duration Healing of EE 12 years to 17 years Esomeprazole magnesium delayed-release capsules: 20 mg or 40 mg once daily 4 to 8 Weeks Treatment of Symptomatic GERD 12 years to 17 years Esomeprazole magnesium delayed-release capsules: 20 mg once

From the Dosage and Administration section of the FDA label we read for Esomeprazole — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

See Every Supplement That Interacts With Esomeprazole

This page covers Octopamine only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Esomeprazole page lists 154 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), St. John's Wort (major), Acacia Rigidula (moderate) and Adrafinil (moderate).

By severity: 3 major · 102 moderate · 49 minor.

From our pharmacist’s overview on the Esomeprazole page

“St. John's wort can lower the amount of esomeprazole (Nexium) in your blood by speeding up how the liver clears it, which can leave heartburn or ulcer treatment falling short.”

About Octopamine

What is Octopamine?

  • Weight loss and fat burning
  • Boosting energy
  • Athletic performance
  • Appetite suppression

Octopamine is a stimulant-like compound found in small amounts in some plants (such as bitter orange) and made naturally in the body. It is marketed mostly in weight-loss and sports supplements, but human evidence that it actually helps with fat loss or performance is very limited. Because it can affect the heart and blood pressure and is banned in some sports, talk to a pharmacist or doctor before using it.

Octopamine is a naturally occurring compound; supplement forms are usually synthetic or derived from bitter orange (Citrus aurantium) peel · Capsules, tablets, powders (often in fat-burner and pre-workout blends)

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

Octopamine: dosing

There is no well-established, standardized dose for octopamine as a supplement. It usually appears in combination products, and amounts vary widely from one brand to another.If you choose to use a product containing octopamine, follow the directions on the label and do not exceed them.

From our Octopamine monograph — the full record covers uses, side effects and every documented interaction.

About Esomeprazole

What Is Esomeprazole Used For?

Brand name: Nexium

Esomeprazole treats problems caused by excess stomach acid. It's used to heal erosive esophagitis (damage to the esophagus from acid), control GERD (gastroesophageal reflux disease) symptoms like heartburn, and protect the stomach lining in people at risk for ulcers caused by NSAIDs (anti-inflammatory pain relievers like ibuprofen).

It's also used as part of a three-drug combination to wipe out H. pylori — a stomach bacteria linked to ulcers — and for people with rare conditions that cause the stomach to overproduce acid, such as Zollinger-Ellison syndrome.

Most-Reported Side Effects for Esomeprazole

From FAERS, the FDA’s public side-effect reporting system (235,235 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Chronic kidney disease 35,589 reports
Acute kidney injury 20,510 reports
Renal failure 16,295 reports
Nausea 13,667 reports
Gastrooesophageal reflux disease 12,006 reports

Taking Octopamine and Esomeprazole Together: Common Questions

Is it safe to take Octopamine with Esomeprazole?
We do not list a known interaction between Octopamine and Esomeprazole. 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 Octopamine and Esomeprazole 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.
Should I take Octopamine and Esomeprazole at the same time of day?
At least one FDA label for a product containing Esomeprazole says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Esomeprazole on its own and move Octopamine to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
How was the Octopamine and Esomeprazole combination checked?
Interactions in our licensed database are recorded against drug classes. Esomeprazole is filed under 6 classifications, and Octopamine has documented interactions with 3 drug classes — none of Esomeprazole'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 Octopamine interact with any other medications?
Yes. Octopamine has 352 documented drug interactions in our database — Esomeprazole 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 Esomeprazole interact with any supplements?
Yes. Esomeprazole has documented interactions with 154 supplements in our database — Octopamine is not one of them. The Esomeprazole interaction page linked on this page lists every one, ranked by severity.
