Tinospora Cordifolia 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 Tinospora Cordifolia 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.

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.

Tinospora Cordifolia safety at a glance

Tinospora Cordifol... overall Use caution Generally used in traditional medicine, but reports of liver injury mean it should be used carefully and under guidance.
Pregnancy Avoid Safety has not been established in pregnancy, so it is best avoided.
Breastfeeding Avoid There is not enough reliable safety information, so avoid use while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Interferon Alfa-2b

Interactions in our licensed database are recorded against drug classes, not just single drug names. Interferon Alfa-2b is filed under 2 classifications — photosensitizing drugs, hepatotoxic drugs. Tinospora Cordifolia has documented interactions with 6 drug classes — the most serious being antidiabetes drugs (moderate), cytochrome p450 1a2 (cyp1a2) substrates (moderate) and cytochrome p450 2c19 (cyp2c19) substrates (moderate) — and none of Interferon Alfa-2b’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

What Tinospora Cordifolia Itself Has Been Linked To

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

  • Liver problems Worth acting on Additional detail

    “Orally, liver injury is reported after consumption of Tinospora cordifolia. In 2 case series, autoimmune hepatitis, acute hepatitis, worsening of chronic liver disease, or acute liver failure is reported in 49 patients after consuming various forms and doses of Tinospora cordifolia alone or in combination with other ingredients for a median of 42-90 days.”

Everything above comes from the Natural Medicines adverse-effect record for Tinospora Cordifolia — expand a row for the licensed statement it rests on. We haven’t matched Interferon Alfa-2b to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Interferon Alfa-2b.

Overlapping uses

What Interferon Alfa-2b Is Prescribed For, and What Tinospora Cordifolia 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. Tinospora Cordifolia is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Tinospora Cordifolia has been studied for:

  • Hepatitis studied, not established Tinospora Cordifolia has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Tinospora Cordifolia for hepatitis

    Although there has been interest in using oral Tinospora cordifolia for hepatitis, there is insufficient reliable information about the clinical effects of Tinospora cordifolia for this purpose.

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

    Tinospora Cordifolia for cancer

    Although there has been interest in using oral Tinospora cordifolia for cancer, there is insufficient reliable information about the clinical effects of Tinospora cordifolia 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 Interferon Alfa-2b on your own; if you are taking Tinospora Cordifolia for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Interferon Alfa-2b

This page covers Tinospora Cordifolia only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Interferon Alfa-2b page lists 57 supplements it has a documented interaction with, worst first, each one explained.

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 Tinospora Cordifolia

What is Tinospora Cordifolia?

  • Immune support
  • Fever
  • Blood sugar support
  • General wellness and 'rejuvenation'
  • Allergic rhinitis
  • Inflammation

Tinospora cordifolia, known as Guduchi or Giloy in Ayurvedic medicine, is a climbing plant traditionally used to support immunity and treat fevers. Early laboratory and small human studies suggest possible immune and blood sugar effects, but high-quality evidence is limited, and there have been reports of liver injury. Talk with your pharmacist or doctor before using it.

Taking Tinospora Cordifolia and Interferon Alfa-2b Together: Common Questions

Is it safe to take Tinospora Cordifolia with Interferon Alfa-2b?
We do not list a known interaction between Tinospora Cordifolia and Interferon Alfa-2b. 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.
Are Tinospora Cordifolia and Interferon Alfa-2b used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Tinospora Cordifolia in each. That is a conversation for your prescriber, especially if Interferon Alfa-2b is being adjusted to a target.
How was the Tinospora Cordifolia and Interferon Alfa-2b combination checked?
Interactions in our licensed database are recorded against drug classes. Interferon Alfa-2b is filed under 2 classifications, and Tinospora Cordifolia has documented interactions with 6 drug classes — none of Interferon Alfa-2b's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Tinospora Cordifolia interact with any other medications?
Yes. Tinospora Cordifolia has 612 documented drug interactions in our database — Interferon Alfa-2b is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Interferon Alfa-2b interact with any supplements?
Yes. Interferon Alfa-2b has documented interactions with 57 supplements in our database — Tinospora Cordifolia is not one of them. The Interferon Alfa-2b interaction page linked on this page lists every one, ranked by severity.
