The bottom line No known interaction

We found no known interaction between Kousso and Alitretinoin 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.

Kousso and Alitretinoin

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 Alitretinoin 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 Alitretinoin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Alitretinoin is filed under 3 classifications — retinoids, photosensitizing drugs, oral drugs. Kousso has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Alitretinoin’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 Alitretinoin. 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 Alitretinoin’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Alitretinoin column appears here.

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.

From our Kousso monograph — the full record covers uses, side effects and every documented interaction.

About Alitretinoin

What Is Alitretinoin Used For?

Brand name: Panretin

Panretin Gel is approved to treat cutaneous lesions — visible skin sores — in adults who have AIDS-related Kaposi's sarcoma (KS), a cancer that causes abnormal tissue to grow in the skin.

Panretin Gel is applied directly to the affected skin spots. It is not for use when the disease has spread widely enough to need systemic (whole-body) treatment — for example, when there are more than 10 new lesions in a month, or when the lungs, lymph nodes, or internal organs are involved.

Most-Reported Side Effects for Alitretinoin

From FAERS, the FDA’s public side-effect reporting system (117 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Drug intolerance 9 reports
Headache 9 reports
Hypercholesterolaemia 8 reports
Treatment failure 8 reports
Vomiting 8 reports
