Drug & supplement interaction

Croton Seeds + Cabotegravir Sodium

Cabotegravir Sodium brand name: Vocabria.

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 Croton Seeds and Cabotegravir Sodium 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 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.

Croton Seeds and Cabotegravir Sodium

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 Cabotegravir Sodium and Croton Seeds 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 Croton Seeds at all — not against Cabotegravir Sodium, 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 Croton Seeds and Cabotegravir Sodium 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.

    “Orally, croton seeds can cause burning of the mouth, vomiting, dizziness, stupor, painful bowel movements, and collapse (18). Topically, croton seed oil can cause itching, burning and blistering of the skin (18).”

“Cabotegravir (Vocabria) is an HIV medicine, and keeping its blood level steady is what keeps the virus suppressed, so I read this list of 29 interacting supplements with genuine concern. The one major entry is activated charcoal, a popular detox remedy that soaks up drugs in the gut and cuts how much reaches you.”

About Croton Seeds

What is Croton Seeds?

  • Severe constipation (traditional purgative)
  • Digestive complaints
  • Skin conditions (topical, traditional)
  • Traditional Chinese and folk medicine remedies

Croton seeds and croton oil come from Croton tiglium, a plant historically used as a powerful purgative, but they are highly toxic and can be dangerous or even deadly. Because of the serious risk of poisoning, severe irritation, and burns, croton seeds are not recommended for self-use. If you are considering any product containing croton, talk to a doctor or pharmacist first.

Croton tiglium · Euphorbiaceae · Seeds and the oil pressed from the seeds (croton oil) · Croton oil, processed seeds, and traditional herbal preparations (rarely available as a standard supplement)

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

Croton Seeds: dosing

There is no safe, standardized dose of croton seeds or croton oil for self-care, and we will not suggest an amount. The difference between a traditional 'dose' and a poisonous amount is very small, which is part of why croton is considered so dangerous.We do not recommend taking croton seeds.
