The bottom line No known interaction

We found no known interaction between Chymotrypsin and Vismodegib 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.

Chymotrypsin and Vismodegib

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 Vismodegib and Chymotrypsin 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 Chymotrypsin at all — not against Vismodegib, 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.

Chymotrypsin safety at a glance

Chymotrypsin overall Use caution Generally tolerated for short-term use, but quality evidence is limited and some people may react to this animal-derived enzyme.
Pregnancy Avoid There is not enough safety information, so it is best to avoid use during pregnancy.
Breastfeeding Avoid Safety while breastfeeding has not been established, so avoiding it is the safer choice.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What Chymotrypsin Itself Has Been Linked To

This is not an interaction — nothing below involves Vismodegib. It is the side-effect record for Chymotrypsin on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Chymotrypsin, this list is the first place to look. 2 entries are worth acting on rather than waiting out — marked below.

    “Rarely, chymotrypsin has been reported to cause anaphylactic reactions characterized by dyspnea, urticaria, edema, shock, vascular collapse, and unconsciousness, which can lead to death (9,509).”

  • A severe allergic reaction / An allergic reaction Worth acting on Additional detail

    “There is currently a limited amount of information available about the adverse effects of chymotrypsin. Orally, hypersensitivity reactions, including anaphylaxis, have been reported (9). When injected into the eye, chymotrypsin has been reported to cause increased intraocular pressure and uveitis (9,509).”

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

Everything else you take

See Every Supplement That Interacts With Vismodegib

This page covers Chymotrypsin only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Vismodegib page lists 57 supplements it has a documented interaction with, worst first, each one explained.

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

By severity: 2 major · 38 moderate · 17 minor.

From our pharmacist’s overview on the Vismodegib page

“St. John's wort can quietly undercut vismodegib (Erivedge), the pill for advanced basal cell carcinoma, by speeding up the gut pump that clears the drug from the body, and a cancer treatment that silently loses potency is the worst kind of interaction.”

About Chymotrypsin

What is Chymotrypsin?

  • Swelling and inflammation after injury or surgery
  • Wound healing
  • Cataract surgery (intracapsular)
  • Sports injuries and sprains
  • Easing soreness and bruising

Chymotrypsin is a protein-digesting (proteolytic) enzyme, usually taken from the pancreas of cattle or pigs, that is mainly used to help reduce swelling and support healing after injury or surgery. The evidence for many of these uses is limited or low quality, so it should not replace standard care. Talk with your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or have a bleeding or clotting condition.

Enzyme derived from animal (typically bovine or porcine) pancreas · Oral tablets (often enteric-coated), topical preparations, injectable forms (in clinical settings)

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

Chymotrypsin: dosing

There is no well-established standard dose of chymotrypsin for supplement use. Strengths vary widely between products, and it is often combined with other enzymes such as trypsin.The best approach is to follow the directions on the product label and not exceed the recommended amount.
