Drug & supplement interaction

Hedge-hyssop + Rilpivirine

Rilpivirine brand names: Edurant, Edurant Ped.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Hedge-hyssop and Rilpivirine 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 Rilpivirine states a food rule worth keeping to.

Hedge-hyssop and Rilpivirine

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 Rilpivirine and Hedge-hyssop 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 Hedge-hyssop at all — not against Rilpivirine, 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 Hedge-hyssop Itself Has Been Linked To

This is not an interaction — nothing below involves Rilpivirine. It is the side-effect record for Hedge-hyssop on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Hedge-hyssop, this list is the first place to look.

  • Passing urine more often / Diarrhea / Vomiting Additional detail

    “Orally, taken in toxic doses, hedge-hyssop may cause vomiting, bloody diarrhea, colic, and kidney irritation characterized by initial diuresis followed by anuria. When people ingest very large amounts, spasms, paralysis, and circulatory collapse occur. Death occurs rarely (18).”

Everything above comes from the Natural Medicines adverse-effect record for Hedge-hyssop — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Rilpivirine’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Rilpivirine column appears here.

How to take them

Some Rilpivirine Products Have a Food Rule — Hedge-hyssop Should Not Break It

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

2 DOSAGE AND ADMINISTRATION One 25 mg rilpivirine tablet taken once daily with a meal for patients weighing at least 35 kg.

From the Dosage and Administration section of the FDA label we read for Rilpivirine — where that label names a specific product, the instruction is that product's. See the Rilpivirine drug page ›

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.

About Hedge-hyssop

What is Hedge-hyssop?

  • Constipation and as a laxative
  • Fluid retention (diuretic use)
  • Liver and digestive complaints
  • Skin conditions (traditional/topical)
  • Inducing vomiting (historical purgative)

Hedge-hyssop is a traditional European herb that was historically used as a strong laxative, diuretic, and purgative, but it is considered toxic and is not recommended for self-treatment. There is no reliable modern evidence that it is safe or effective, and serious poisoning has been reported, so it is best avoided.

Gratiola officinalis · Plantaginaceae · Aerial parts (leaves and flowering stems), sometimes the root · Dried herb, tincture, and historically homeopathic preparations

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

Hedge-hyssop: dosing

There is no established safe or standardized dose of hedge-hyssop. Because the plant is toxic and the margin between a traditional dose and a harmful dose is narrow, no specific amount can be recommended.We do not advise self-treating with this herb.

About Rilpivirine

What Is Rilpivirine Used For?

Brand names: Edurant, Edurant Ped

Rilpivirine tablets (sold as Edurant, Edurant Ped, and generic rilpivirine) are used along with other antiretroviral medicines to treat HIV-1 infection in patients who have not previously been treated with HIV medicines (treatment-naïve). Eligibility depends on age, body weight, and the level of virus in the blood at the start of treatment.

Edurant tablets are also approved, in combination with cabotegravir (Vocabria), for short-term oral use in adults and adolescents who are already virologically suppressed — specifically as a lead-in before starting the long-acting injectable regimen Cabenuva, or as a bridge if a Cabenuva injection dose will be missed.

Most-Reported Side Effects for Rilpivirine

From FAERS, the FDA’s public side-effect reporting system (24,864 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Taking Hedge-hyssop and Rilpivirine Together: Common Questions

Is it safe to take Hedge-hyssop with Rilpivirine?

At least one FDA label for a product containing Rilpivirine says to take it with food. If you take Hedge-hyssop on an empty stomach out of habit, keep them separate and take Rilpivirine with a meal where the label says to.
