Interaction report

Brickellia 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 Brickellia 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.

How we checked

Why No Interaction Is Listed for Glecaprevir, Pibrentasvir

Interactions in our licensed database are recorded against drug classes, not just single drug names. Glecaprevir, Pibrentasvir is filed under 3 classifications — p-glycoprotein substrates, cytochrome p450 3a4 (cyp3a4) substrates, oral drugs. Brickellia has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Glecaprevir, Pibrentasvir’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 Glecaprevir, Pibrentasvir’s Own FDA Label Lists

This is not an interaction — none of it involves Brickellia. These are the most notable effects listed in the ADVERSE REACTIONS section of Glecaprevir, Pibrentasvir’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 5 of them are worth acting on rather than waiting out — marked below.

  • Yellowing of the skin or eyes Worth acting on
  • Kidney problems Worth acting on
  • A severe allergic reaction Worth acting on
  • Liver problems Worth acting on
  • A higher chance of infection Worth acting on
  • Tiredness mentioned in 23.5% of FDA reports for Glecaprevir, Pibrentasvir
  • Headache mentioned in 20.2% of FDA reports for Glecaprevir, Pibrentasvir
  • Itching mentioned in 6.0% of FDA reports for Glecaprevir, Pibrentasvir
  • Stomach pain
  • Nausea mentioned in 10.4% of FDA reports for Glecaprevir, Pibrentasvir

Showing the 10 most notable of 13 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Glecaprevir, Pibrentasvir. Read the label on DailyMed › Where a percentage is shown, it is the share of 10,923 voluntary FDA FAERS reports for Glecaprevir, Pibrentasvir that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Brickellia’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Brickellia side to compare — that is a limit of the record, not a statement that Brickellia has no side effects.

How to take them

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

At least one FDA label for a product containing Glecaprevir, Pibrentasvir says to take it with food. If you take Brickellia 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 Brickellia

What is Brickellia?

  • Blood sugar support (diabetes)
  • Digestive complaints
  • Gallbladder and bile flow
  • Colds and fever

Brickellia, often sold under names like 'prodigiosa' or as a Mexican folk remedy for diabetes, is a plant in the daisy family traditionally brewed as a tea. Scientific evidence in humans is very limited, so its effectiveness and long-term safety are not well established. Talk with your pharmacist or doctor before using it, especially if you take medicines for blood sugar.

Brickellia grandiflora · Asteraceae · Leaves and flowering tops · Tea (infusion), dried herb, tincture, capsules

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

Brickellia: dosing

There is no established standardized dose for Brickellia. Traditional use is usually as a tea made from the dried leaves and flowering tops, but the strength of homemade preparations varies widely.If you choose to use a commercial product, follow the directions on the label and do not exceed them.
