Drug & supplement interaction

Shark Liver Oil + Pegloticase

Pegloticase brand name: Krystexxa.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 27, 2026
The bottom line No known interaction

We found no known interaction between Shark Liver Oil and Pegloticase 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.

Shark Liver Oil and Pegloticase

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 Pegloticase 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 Pegloticase, 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 Pegloticase 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.

  • Tiredness 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.”

    Pegloticase

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

Reported for Shark Liver Oil but not commonly for Pegloticase: stomach upset, liver problems, a higher chance of infection and itching.

Effects for Pegloticase 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. Where a percentage is shown, it is the share of 3,424 voluntary FDA FAERS reports for Pegloticase 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 Pegloticase

This page covers Shark Liver Oil only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Pegloticase page lists 1 supplement it has a documented interaction with, worst first, each one explained.

The most serious there right now: Inosine (moderate).

By severity: 1 moderate.

From our pharmacist’s overview on the Pegloticase page

“Inosine is the one supplement on record that can work against pegloticase (Krystexxa), the IV enzyme infused for severe gout that has stopped responding to standard treatment. Inosine raises uric acid in the blood and urine, which is precisely what pegloticase exists to lower, so combining the two could blunt the very benefit those inf…”

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.

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 Pegloticase Injection

What Is Pegloticase Injection Used For?

Brand name: Krystexxa

Krystexxa is used to treat chronic gout in adults whose gout has not responded to conventional treatments — either because standard uric-acid-lowering medications (like xanthine oxidase inhibitors) haven't brought uric acid to a normal level, or because those drugs cannot be used.

Krystexxa is not recommended for people who have high uric acid levels but no gout symptoms (a condition called asymptomatic hyperuricemia).

Most-Reported Side Effects for Pegloticase

From FAERS, the FDA’s public side-effect reporting system (3,686 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Gout 562 reports
Blood uric acid increased 405 reports
Infusion related reaction 365 reports
Therapeutic response decreased 240 reports
Dyspnea 180 reports

Taking Shark Liver Oil and Pegloticase Together: Common Questions

Is it safe to take Shark Liver Oil with Pegloticase?

Do Shark Liver Oil and Pegloticase 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.

Does Pegloticase interact with any supplements?
Yes. Pegloticase has documented interactions with 1 supplement in our database — Shark Liver Oil is not one of them. The Pegloticase interaction page linked on this page lists every one, ranked by severity.
