Drug & supplement interaction

Irvingia Gabonensis + Ribavirin

Ribavirin brand names: Rebetol, Copegus, Ribasphere, Moderiba.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Irvingia Gabonensis and Ribavirin 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 Ribavirin 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

Irvingia Gabonensis and Ribavirin

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 Ribavirin and Irvingia Gabonensis 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.

Irvingia Gabonensis safety at a glance

Irvingia Gabonensi... overall Use caution Generally tolerated short-term in studies, but long-term safety and product quality are not well established.
Pregnancy Avoid Not enough safety data, so it is best avoided during pregnancy.
Breastfeeding Avoid No reliable safety information is available 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 Ribavirin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ribavirin is filed under a single classification — oral drugs. Irvingia Gabonensis has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and testosterone (moderate) — and none of Ribavirin’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

No Interaction Found — But Data Suggests Irvingia Gabonensis and Ribavirin 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.

  • Tiredness / Stomach upset reported in 15.0% of FDA reports for Ribavirin Additional detail

    Irvingia Gabonensis

    “One case of acute hepatitis secondary to Irvingia gabonensis has been reported.

Reported for Irvingia Gabonensis but not commonly for Ribavirin: bloating or gas, liver problems and yellowing of the skin or eyes.

Effects for Ribavirin come from the ADVERSE REACTIONS section of its FDA label; effects for Irvingia Gabonensis come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 63,877 voluntary FDA FAERS reports for Ribavirin 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.

How to take them

Some Ribavirin Products Have a Food Rule — Irvingia Gabonensis Should Not Break It

At least one FDA label for a product containing Ribavirin says to take it with food. If you take Irvingia Gabonensis on an empty stomach out of habit, keep them separate — and take Ribavirin 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 Ribavirin 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.

Ribavirin capsules should be taken with food [see Clinical Pharmacology (12.3) ].

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

See Every Supplement That Interacts With Ribavirin

This page covers Irvingia Gabonensis only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Ribavirin page lists 17 supplements it has a documented interaction with, worst first, each one explained.

By severity: 1 major · 7 moderate · 9 minor.

From our pharmacist’s overview on the Ribavirin page

“Nearly every entry on this ribavirin page pulls the same lever, changing how much of the drug reaches your bloodstream, and that deserves genuine care here. Ribavirin (Rebetol, Copegus) is an antiviral for hepatitis C, and treatment succeeds only when levels stay steady enough to keep the virus in check, so anything that quietly lowers…”

About Irvingia Gabonensis

What is Irvingia Gabonensis?

Irvingia Gabonensis
  • Weight loss
  • Appetite control
  • Cholesterol support
  • Blood sugar support
  • Metabolism support

Irvingia gabonensis (African mango) is a seed extract marketed mainly for weight loss and metabolic health. A few small studies suggest possible benefits, but the research is limited and low-quality, so the true effect is uncertain. Talk with your pharmacist or doctor before using it, and do not rely on it in place of proven diet and lifestyle changes.

Irvingia gabonensis · Irvingiaceae · Seed (kernel, also called dika nut); seed extract · Capsules, tablets, powder, standardized seed extract

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

Irvingia Gabonensis: dosing

There is no officially established or standardized dose for Irvingia gabonensis. Studies have used different seed extracts and amounts, so it is hard to recommend one specific dose.If you choose to try it, follow the directions on the product label and do not exceed them.

About Ribavirin

What Is Ribavirin Used For?

Brand names: Rebetol, Copegus, Ribasphere, Moderiba

Ribavirin comes in different forms for different uses. Ribavirin capsules are used in combination with interferon alfa-2b (pegylated or non-pegylated) to treat chronic hepatitis C (CHC) in patients 3 years and older with compensated liver disease. Ribavirin tablets are used in combination with PEGASYS® (peginterferon alfa-2a) to treat chronic hepatitis C in patients 5 years and older with compensated liver disease who have not previously been treated with interferon — including adults who also have HIV. Ribavirin for inhalation solution is a separate product used to treat hospitalized infants and young children with severe lower respiratory tract infections caused by respiratory syncytial virus (RSV).

Ribavirin must never be used alone to treat hepatitis C — it only works as part of combination therapy. Only the most severe RSV infections requiring hospitalization should be treated with the inhaled form; mild RSV illness in children does not require this treatment.

Taking Irvingia Gabonensis and Ribavirin Together: Common Questions

Is it safe to take Irvingia Gabonensis with Ribavirin?
We do not list a known interaction between Irvingia Gabonensis and Ribavirin. 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 Irvingia Gabonensis and Ribavirin have any of the same side effects?
Yes — our sources link each of them separately to 5 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 Irvingia Gabonensis and Ribavirin at the same time of day?
At least one FDA label for a product containing Ribavirin says to take it with food. If you take Irvingia Gabonensis on an empty stomach out of habit, keep them separate and take Ribavirin with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Ribavirin products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Irvingia Gabonensis and Ribavirin combination checked?
Interactions in our licensed database are recorded against drug classes. Ribavirin is filed under 1 classification, and Irvingia Gabonensis has documented interactions with 2 drug classes — none of Ribavirin'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 Irvingia Gabonensis interact with any other medications?
Yes. Irvingia Gabonensis has 94 documented drug interactions in our database — Ribavirin 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 Ribavirin interact with any supplements?
Yes. Ribavirin has documented interactions with 17 supplements in our database — Irvingia Gabonensis is not one of them. The Ribavirin interaction page linked on this page lists every one, ranked by severity.
