Drug & supplement interaction

Ignatius Bean + Glecaprevir, Pibrentasvir

Glecaprevir, Pibrentasvir brand name: Mavyret.

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 Ignatius Bean and Glecaprevir, Pibrentasvir 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 Glecaprevir, Pibrentasvir 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

Ignatius Bean and Glecaprevir, Pibrentasvir

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 Glecaprevir, Pibrentasvir and Ignatius Bean 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 Ignatius Bean at all — not against Glecaprevir, Pibrentasvir, 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

No Interaction Found — But Data Suggests Ignatius Bean and Glecaprevir, Pibrentasvir 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. 2 of them are worth acting on rather than waiting out — marked below.

    Ignatius Bean

    “Orally, Ignatius bean is generally regarded as unsafe for use. Any benefits of therapy may not outweigh the risk of toxicity. Ignatius bean 30-50 mg, which contains approximately 5 mg of strychnine, can cause restlessness, anxiety, heightened sense perception, enhanced reflexes, equilibrium disorders, painful back and neck stiffness, twitching, spasms of jaw and neck muscles, myoglobinuric renal failure, rhabdomyolys…”

How to take them

Some Glecaprevir, Pibrentasvir Products Have a Food Rule — Ignatius Bean Should Not Break It

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

Recommended dosage in adults: Three tablets taken at the same time orally once daily (total daily dose: glecaprevir 300 mg and pibrentasvir 120 mg) with food.

From the Dosage and Administration section of the FDA label we read for Glecaprevir, Pibrentasvir — 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.

From our pharmacist’s overview on the Glecaprevir, Pibrentasvir page

“Mavyret (glecaprevir and pibrentasvir) is a short course of pills meant to cure hepatitis C, so I read its supplement list with real caution. Nearly everything on it can shift how much of the drug reaches your blood, mostly through the CYP3A4 enzyme or the P-glycoprotein transporter that handles it.”

About Ignatius Bean

What is Ignatius Bean?

Ignatius Bean
  • Grief, sadness, and emotional upset (homeopathic use)
  • Anxiety and stress (homeopathic use)
  • Mood swings
  • Digestive complaints (traditional use)
  • Historically used as a stimulant or for paralysis

Ignatius bean is a seed that naturally contains strychnine and brucine, which are highly toxic poisons. The raw seed or crude extracts should never be taken because even small amounts can cause dangerous muscle spasms and death. Today it is mainly seen in highly diluted homeopathic products (Ignatia), and you should talk to a pharmacist or doctor before using anything made from this plant.

Strychnos ignatii · Loganiaceae · Seed (the dried ripe seed, called the bean) · Homeopathic pellets and dilutions (Ignatia amara); raw seed is not used as a regular supplement

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

Ignatius Bean: dosing

There is no safe established dose of crude Ignatius bean. Because the seed contains strychnine, taking measured amounts of the raw plant is dangerous and is not recommended under any circumstances.Homeopathic Ignatia products come in their own dilutions and pellet strengths, with directions on the label.
