Drug & supplement interaction

Shark Liver Oil + Amiloride

Amiloride brand names: Midamor, Amilamont.

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 Shark Liver Oil and Amiloride 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 Amiloride 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.

Interaction report

Shark Liver Oil and Amiloride

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 Amiloride and Shark Liver Oil 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 Shark Liver Oil at all — not against Amiloride, 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.

No Interaction Found — But Data Suggests Shark Liver Oil and Amiloride 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. 2 of them are worth acting on rather than waiting out — marked below.

  • Yellowing of the skin or eyes / Liver problems Worth acting on Additional detail

    Shark Liver Oil

    “Orally, a case of severe acute hepatitis probably related to use of shark liver oil twice daily for 2 weeks has been reported. The patient presented with abdominal discomfort, jaundice, malaise, pruritus, and elevated levels of bilirubin and liver enzymes. Other potential causes were ruled out.”

Reported for Shark Liver Oil but not commonly for Amiloride: a higher chance of infection and tiredness.

Effects for Amiloride come from the ADVERSE REACTIONS section of its FDA label; effects for Shark Liver Oil come from the Natural Medicines adverse-effect record, quoted above. 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 Amiloride Products Have a Food Rule — Shark Liver Oil Should Not Break It

At least one FDA label for a product containing Amiloride says to take it with food. If you take Shark Liver Oil on an empty stomach out of habit, keep them separate — and take Amiloride with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Amiloride 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.

DOSAGE AND ADMINISTRATION Amiloride HCl should be administered with food.

From the Dosage and Administration section of the FDA label we read for Amiloride — 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.

From our pharmacist’s overview on the Amiloride page

“Amiloride (Midamor) is a water pill that lowers blood pressure while holding onto potassium, and both of those jobs give supplements openings to cause trouble, so I would read this list with real care. Four of the 143 ingredients on file carry a major rating, including tyramine and American mistletoe, which can push blood pressure up a…”

About Shark Liver Oil

What is Shark Liver Oil?

  • Immune support
  • Skin conditions and wound healing
  • Cancer support (unproven)
  • Hemorrhoid relief (topical)
  • Cold and flu prevention
  • General wellness tonic

Shark liver oil is taken from the livers of deep-sea sharks and is rich in compounds called alkylglycerols and squalene. People use it for immune support, skin healing, and other conditions, but strong human evidence is largely lacking. Talk to your pharmacist or doctor before using it, especially since sustainability and contamination are concerns.

Liver oil from deep-sea sharks · Capsules, softgels, liquid oil, topical creams and ointments

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

Shark Liver Oil: dosing

There is no official or well-established dose for shark liver oil. Products differ in how much alkylglycerol or squalene they contain, so amounts on labels vary.The safest approach is to follow the directions on the product label and not take more than recommended.

About Amiloride

What Is Amiloride Used For?

Brand names: Midamor, Amilamont

Amiloride is used together with other diuretics (water pills) to treat congestive heart failure and high blood pressure (hypertension). It is added to a thiazide or similar diuretic to either restore low potassium levels or prevent them from dropping dangerously in the first place.

It is especially useful for people who are at particular risk if their potassium falls too low — for example, those taking digoxin or those with significant heart rhythm problems. Amiloride is rarely used on its own, as its diuretic and blood-pressure-lowering effects are weak compared with other diuretics.

Taking Shark Liver Oil and Amiloride Together: Common Questions

Is it safe to take Shark Liver Oil with Amiloride?
We do not list a known interaction between Shark Liver Oil and Amiloride. 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 Shark Liver Oil and Amiloride have any of the same side effects?
Yes — our sources link each of them separately to 4 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 Shark Liver Oil and Amiloride at the same time of day?
At least one FDA label for a product containing Amiloride says to take it with food. If you take Shark Liver Oil on an empty stomach out of habit, keep them separate and take Amiloride with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Amiloride products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Does Amiloride interact with any supplements?
Yes. Amiloride has documented interactions with 143 supplements in our database — Shark Liver Oil is not one of them. The Amiloride interaction page linked on this page lists every one, ranked by severity.
