No Known Interaction
The bottom line No known interaction

We found no known interaction between Apricot Kernel and Interferon Alfa-2b 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.

Apricot Kernel and Interferon Alfa-2b

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 Interferon Alfa-2b and Apricot Kernel 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 Apricot Kernel at all — not against Interferon Alfa-2b, 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 Apricot Kernel Itself Has Been Linked To

This is not an interaction — nothing below involves Interferon Alfa-2b. It is the side-effect record for Apricot Kernel on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Apricot Kernel, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Loss of vision / Unsteadiness / Confusion / Seizures / Hives / Liver problems Worth acting on Additional detail

    “Apricot kernel contains amygdalin, which is converted to cyanide in the body and can cause cyanide poisoning. Signs of acute cyanide poisoning include abdominal pain, nausea, vomiting, diarrhea, dizziness, headache, hives, rash, itchy or swollen skin, cyanosis, light-headedness, confusion, weakness, drowsiness, palpitations, hyperpnea, seizures, hypotension, and trembling.”

Overlapping uses

What Interferon Alfa-2b Is Prescribed For, and What Apricot Kernel Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Interferon Alfa-2b is a prescription medicine with approved uses on its FDA label. Apricot Kernel is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Apricot Kernel has been studied for:

  • Cancer studied, not established Apricot Kernel has been studied for this. Natural Medicines rates the evidence: Possibly Ineffective Read what the research shows

    Apricot Kernel for cancer

    Oral apricot kernel does not seem to be effective for cancer.

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 Interferon Alfa-2b on your own; if you are taking Apricot Kernel for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Interferon Alfa-2b page

“People taking interferon alfa-2b (Intron A, Rebetron) are usually treating hepatitis or a cancer, so the liver may already be under strain, and that is exactly where most of this list points. Of the 57 supplements on file, 38 can add to liver stress, and all three major-rated interactions sit in that group: Siberian cocklebur, which ha…”

About Apricot Kernel

What is Apricot Kernel?

Apricot Kernel
  • Claimed anti-cancer remedy (unproven)
  • Cough and respiratory complaints (traditional medicine)
  • Digestive complaints (traditional medicine)
  • Skin and hair care (kernel oil)
  • General 'detox' or wellness claims

Apricot kernels contain amygdalin (marketed as laetrile or 'vitamin B17'), which the body can convert into cyanide and cause serious, even fatal, poisoning. There is no reliable evidence that apricot kernels or laetrile treat cancer or any other disease, and health authorities warn against eating them. The pressed oil used on skin is a separate, generally lower-risk product.

Prunus armeniaca · Rosaceae · Seed (kernel) inside the apricot pit, and the oil pressed from it · Raw or ground kernels, capsules, amygdalin/laetrile supplements, apricot kernel oil

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

Apricot Kernel: dosing

There is no safe, established, or recommended dose of apricot kernels or amygdalin/laetrile for treating any health condition. We will not suggest specific amounts because even small quantities can be unsafe. Apricot kernel oil used on the skin should be used as directed on the cosmetic product label.

    • along with another medication to treat follicular non-Hodgkin's lymphoma (NHL; a slow-growing blood cancer).

  • Interferon alfa-2b is in a class of medications called immunomodulators. Interferon alfa-2b works to treat hepatitis C virus (HCV) and hepatitis B virus (HBV) by decreasing the amount virus in the body.
