The bottom line No known interaction

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

Shark Liver Oil and Abiraterone

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 Abiraterone 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 Abiraterone, 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.

What to actually watch for

What Shark Liver Oil Itself Has Been Linked To

This is not an interaction — nothing below involves Abiraterone. It is the side-effect record for Shark Liver Oil on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Shark Liver Oil, this list is the first place to look. 2 entries are worth acting on rather than waiting out — marked below.

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

    “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.”

Everything above comes from the Natural Medicines adverse-effect record for Shark Liver Oil — expand a row for the licensed statement it rests on.

Overlapping uses

What Abiraterone Is Prescribed For, and What Shark Liver Oil Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Abiraterone is a prescription medicine with approved uses on its FDA label. Shark Liver Oil is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Abiraterone is prescribed for: Abiraterone acetate tablets are used to treat two types of advanced prostate cancer: metastatic castration-resistant prostate cancer (CRPC — cancer that has spread and keeps growing despite low testosterone levels) and metastatic high-risk castration-sensitive prostate cancer (CSPC — cancer that has spread but still responds to hormone-lowering treatment). It is always taken together with a corticosteroid — most products pair with prednisone, while Yonsa is specifically indicated with methylprednisolone. All products — including Abiraterone, Abiraterone Acetate, Abirtega, Yonsa, and Zytiga — are taken by mouth as a tablet. Yonsa is approved only for metastatic CRPC, while the other products (Abiraterone, Abiraterone Acetate, Abirtega, and Zytiga) are approved for both metastatic CRPC and metastatic high-risk CSPC.

Shark Liver Oil has been studied for:

  • Cancer studied, not established Shark Liver Oil has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Shark Liver Oil for cancer

    Although there has been interest in using oral shark liver oil for cancer, there is insufficient reliable information about the clinical effects of shark liver oil for this purpose.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Abiraterone on your own; if you are taking Shark Liver Oil for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

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.

It is always taken together with a corticosteroid — most products pair with prednisone, while Yonsa is specifically indicated with methylprednisolone.

Yonsa is approved only for metastatic CRPC, while the other products (Abiraterone, Abiraterone Acetate, Abirtega, and Zytiga) are approved for both metastatic CRPC and metastatic high-risk CSPC.

Is it safe to take Shark Liver Oil with Abiraterone?

They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together.
