Drug & supplement interaction

Nux Vomica + Ustekinumab

Ustekinumab brand name: Stelara.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Nux Vomica and Ustekinumab 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.

Nux Vomica and Ustekinumab

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 Ustekinumab and Nux Vomica 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 Nux Vomica at all — not against Ustekinumab, 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 Nux Vomica and Ustekinumab May Share a Side Effect

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.

  • Dizziness Additional detail

    Nux Vomica

    “Orally, 30-50 mg nux vomica (5 mg strychnine) can cause restlessness, feelings of anxiety, heightening of sense perception, enhanced reflexes, equilibrium disorders, painful neck and back stiffness, followed later by twitching, tonic spasms of jaw and neck muscles, painful convulsions of the entire body triggered by visual or tactile stimulation with possible opisthotonos, muscle hypertonicity and agitation.”

    Ustekinumab

    Listed in the ADVERSE REACTIONS section of the FDA label for Ustekinumab. Read the label on DailyMed ›

Reported for Nux Vomica but not commonly for Ustekinumab: severe muscle breakdown, kidney problems, anxiety or restlessness and liver problems.

Effects for Ustekinumab come from the ADVERSE REACTIONS section of its FDA label; effects for Nux Vomica come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 100,563 voluntary FDA FAERS reports for Ustekinumab that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

About Nux Vomica

What is Nux Vomica?

  • Digestive upset and indigestion
  • Nausea and constipation
  • Hangover symptoms
  • Sleep problems and irritability
  • General 'detox' or tonic use in traditional medicine

Nux vomica comes from a tree seed that contains strychnine, a powerful and potentially deadly poison. It is mostly sold today in extremely diluted homeopathic forms, and there is no good scientific evidence that it treats any condition. Because even small amounts of the raw or concentrated material can cause severe poisoning, it is best avoided unless you are using a properly prepared product under professional guidance.

Strychnos nux-vomica · Loganiaceae · Dried seeds (and sometimes bark) · Homeopathic pellets and liquids, highly diluted preparations

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

Nux Vomica: dosing

There is no established safe dose of nux vomica as a dietary supplement, and we do not recommend using raw or concentrated forms at all. The difference between a traditional 'small' amount and a toxic amount can be very small.Homeopathic products list their own dilutions on the label (such as 6C or 30C). If you choose to use one, follow the product label exactly and do not exceed it.

Taking Nux Vomica and Ustekinumab Together: Common Questions

Is it safe to take Nux Vomica with Ustekinumab?
We do not list a known interaction between Nux Vomica and Ustekinumab. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Nux Vomica and Ustekinumab have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Does Ustekinumab interact with any supplements?
Yes. Ustekinumab has documented interactions with 53 supplements in our database — Nux Vomica is not one of them. The Ustekinumab interaction page linked on this page lists every one, ranked by severity.
