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

We found no known interaction between Kousso and Vericiguat 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 Vericiguat states a food rule worth keeping to.

Kousso and Vericiguat

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 Vericiguat and Kousso 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 Vericiguat

Interactions in our licensed database are recorded against drug classes, not just single drug names. Vericiguat is filed under 2 classifications — p-glycoprotein substrates, oral drugs. Kousso has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Vericiguat’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 Kousso Itself Has Been Linked To

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

  • Fainting Worth acting on Additional detail

    “Orally, kousso can cause gastrointestinal irritation, resulting in salivation, nausea, and diarrhea. It can also cause headache and general weakness (18). At high doses, vision disorders, spasms, and syncope can occur, progressing to acidosis, and shock (18).”

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

How to take them

Some Vericiguat Products Have a Food Rule — Kousso Should Not Break It

At least one FDA label for a product containing Vericiguat says to take it with food. If you take Kousso on an empty stomach out of habit, keep them separate — and take Vericiguat 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 Vericiguat 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 The recommended starting dose of VERQUVO is 5 mg orally once daily with food.

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

Everything else you take

See Every Supplement That Interacts With Vericiguat

The most serious there right now: Activated Charcoal (major), St. John's Wort (major), Bitter Melon (moderate), Black Pepper (moderate) and Bulbine Natalensis (moderate).

From our pharmacist’s overview on the Vericiguat page

“No supplement on this page worries me more for vericiguat (Verquvo) users than St. John's wort.”

About Kousso

What is Kousso?

  • Tapeworm infection (traditional anthelmintic)
  • Other intestinal worms
  • Traditional digestive remedies

Kousso is the dried flower of the African tree Hagenia abyssinica, used traditionally—especially in Ethiopia—to expel tapeworms. It was once listed in older pharmacopeias as a worm treatment, but it has largely been replaced by safer, more reliable modern medicines and can cause significant side effects. There is no good modern evidence supporting its use, so talk to a pharmacist or doctor before considering it.

Hagenia abyssinica · Rosaceae · Dried female flowers · Dried flower powder, infusion (tea), and traditional liquid preparations

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

Kousso: dosing

There is no well-established, standardized modern dose for kousso. Traditional preparations varied widely and were not measured in the careful way modern medicines are.Because of the lack of standardization and the risk of side effects, we cannot recommend a specific amount.

Taking Kousso and Vericiguat Together: Common Questions

Is it safe to take Kousso with Vericiguat?

Should I take Kousso and Vericiguat at the same time of day?
At least one FDA label for a product containing Vericiguat says to take it with food. If you take Kousso on an empty stomach out of habit, keep them separate and take Vericiguat with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Vericiguat products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Kousso and Vericiguat combination checked?
Interactions in our licensed database are recorded against drug classes. Vericiguat is filed under 2 classifications, and Kousso has documented interactions with 1 drug class — none of Vericiguat'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 Kousso interact with any other medications?
Yes. Kousso has 86 documented drug interactions in our database — Vericiguat 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 Vericiguat interact with any supplements?
