Drug & supplement interaction

Secretin + Ethacrynic Acid

Ethacrynic Acid brand name: Edecrin.

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 Secretin and Ethacrynic Acid 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.

Secretin and Ethacrynic Acid

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 Ethacrynic Acid and Secretin 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Secretin at all — not against Ethacrynic Acid, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

Secretin safety at a glance

Secretin overall Use caution Secretin is a prescription injectable given only by trained healthcare providers, not a self-care supplement.
Pregnancy Not established Safety during pregnancy is not well established; use only if a doctor decides the benefit outweighs the risk.
Breastfeeding Not established It is not known whether secretin is safe during breastfeeding, so caution is advised.

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

What to actually watch for

No Interaction Found — But Data Suggests Secretin and Ethacrynic Acid 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. One of them is worth acting on rather than waiting out — marked below.

  • Pancreatitis Worth acting on Additional detail

    Secretin

    “Intravenously, the most common adverse reaction to secretin is flushing of the face, neck, and chest immediately after infusion. Less common potential adverse effects are vomiting, diarrhea, fainting, venous thrombosis (15), fever, and tachycardia. Some patients can have allergic reactions including urticaria, erythema, and anaphylaxis.”

From our pharmacist’s overview on the Ethacrynic Acid page

“Ethacrynic acid (Edecrin) is a potent loop diuretic, a water pill used to pull off serious fluid buildup, and its supplement list deserves genuine care, starting with the seven entries rated major. Most of the 201 interactions on file either stack with its blood-pressure-lowering effect, risking dizziness or faintness, or work against…”

About Secretin

What is Secretin?

  • Diagnostic testing of pancreas function
  • Diagnosing gastrinoma (Zollinger-Ellison syndrome)
  • Aiding pancreatic imaging procedures
  • Investigational use in autism (not proven)

Secretin is a natural digestive hormone, not a typical dietary supplement. As a medicine it is an FDA-approved injectable used mainly for diagnostic tests of the pancreas, and it must be given by a healthcare professional. Despite past interest, there is strong evidence that secretin does NOT help autism, and it should never be self-administered.

Hormone produced naturally in the small intestine; pharmaceutical versions are made synthetically or from animal sources · Injectable solution (prescription, used in medical settings)

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

Secretin: dosing

There is no general supplement dose for secretin because it is not used as a supplement. It is a prescription injectable, and the dose is calculated by your healthcare provider based on your body and the specific test being done.You should never try to obtain or self-administer secretin. Dosing, timing, and monitoring are all handled by trained medical staff during a procedure.

About Ethacrynic Acid

What Is Ethacrynic Acid Used For?

Brand name: Edecrin

Ethacrynic acid tablets (sold as Edecrin and Ethacrynic Acid) are used to treat edema — excess fluid that builds up in the body — when other, milder diuretics aren't strong enough. It treats edema related to congestive heart failure, cirrhosis of the liver, and kidney disease, including nephrotic syndrome (a kidney condition that causes protein loss and swelling).

It is also used for short-term management of fluid buildup from malignancy (cancer-related ascites), idiopathic edema (swelling with no clear cause), and lymphedema (swelling from a blocked lymph system). In hospitalized children (not infants), it may be used short-term for edema related to congenital heart disease or nephrotic syndrome.

Most-Reported Side Effects for Ethacrynic Acid

From FAERS, the FDA’s public side-effect reporting system (544 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Drug reaction with eosinophilia and systemic symptoms 59 reports
Nausea 47 reports
Dyspnea 43 reports
Acute kidney injury 33 reports
Diarrhea 33 reports

Taking Secretin and Ethacrynic Acid Together: Common Questions

Is it safe to take Secretin with Ethacrynic Acid?
We do not list a known interaction between Secretin and Ethacrynic Acid. 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 Secretin and Ethacrynic Acid have any of the same side effects?
Yes — our sources link each of them separately to 5 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.
Does Ethacrynic Acid interact with any supplements?
Yes. Ethacrynic Acid has documented interactions with 201 supplements in our database — Secretin is not one of them. The Ethacrynic Acid interaction page linked on this page lists every one, ranked by severity.
