Stavesacre and Mobocertinib Succinate

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 Mobocertinib Succinate and Stavesacre 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 Stavesacre at all — not against Mobocertinib Succinate, 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 Stavesacre Itself Has Been Linked To

Everything above comes from the Natural Medicines adverse-effect record for Stavesacre — expand a row for the licensed statement it rests on. We haven’t matched Mobocertinib Succinate to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Mobocertinib Succinate.

From our pharmacist’s overview on the Mobocertinib Succinate page

“Mobocertinib (Exkivity) is a targeted therapy for a hard-to-treat lung cancer, which makes dosing precision matter and this list worth real caution. Most of the 146 supplements on file can shift the drug's blood level, because mobocertinib is cleared by CYP3A4, an enzyme many botanicals speed up or slow down.”

About Stavesacre

What is Stavesacre?

  • Head lice and body lice
  • Skin parasites and scabies
  • Toothache (traditional)
  • Homeopathic remedy for various complaints

Stavesacre is a flowering plant whose seeds were historically used to kill lice and other parasites because they contain toxic alkaloids. It is highly poisonous if swallowed, modern safety data are very limited, and far safer lice treatments now exist, so it is not recommended for internal use.

Delphinium staphisagria · Ranunculaceae · Seeds · Topical preparations, lotions, homeopathic remedies, historically powdered seeds

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

Stavesacre: dosing

There is no established safe or standardized dose for stavesacre, and it is not recommended for internal use because of its toxicity. Because of the poisoning risk, it should not be taken by mouth in any amount.If you come across a topical or homeopathic product containing stavesacre, follow the product label carefully and use it only as directed.

About Mobocertinib

What Is Mobocertinib Used For?

Brand name: Exkivity

  • Mobocertinib is used to treat a certain type of non-small cell lung cancer (NSCLC) that cannot be removed by surgery and has spread to other parts of the body either during or after treatment with platinum chemotherapy medications. Mobocertinib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps stop or slow the spread of cancer cells and may help shrink tumors.
