Enzyme Therapy and Aprepitant

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 Aprepitant and Enzyme Therapy 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 Enzyme Therapy at all — not against Aprepitant, 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

What Aprepitant’s Own FDA Label Lists

This is not an interaction — none of it involves Enzyme Therapy. These are the most notable effects listed in the ADVERSE REACTIONS section of Aprepitant’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • A bowel blockage Worth acting on
  • Dehydration Worth acting on
  • Low sodium Worth acting on
  • Low potassium Worth acting on
  • A slow heartbeat Worth acting on
  • High blood sugar Worth acting on
  • Fainting Worth acting on
  • A severe skin reaction Worth acting on
  • A low platelet count Worth acting on
  • Kidney problems Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Aprepitant. Read the label on DailyMed › Enzyme Therapy’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Enzyme Therapy side to compare — that is a limit of the record, not a statement that Enzyme Therapy has no side effects.

See Every Supplement That Interacts With Aprepitant

This page covers Enzyme Therapy only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Aprepitant page lists 158 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), St. John's Wort (major), Acacia Rigidula (moderate) and Adrafinil (moderate).

By severity: 3 major · 116 moderate · 39 minor.

From our pharmacist’s overview on the Aprepitant page

“Aprepitant (Emend, Cinvanti) keeps chemotherapy patients from vomiting, so a supplement that undoes it mid-cycle is a problem, and I read this list with genuine vigilance. Nearly all 158 entries touch CYP3A4, the liver enzyme that clears aprepitant.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Enzyme Therapy is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Enzyme Therapy reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 27, 2026. The Enzyme Therapy and Aprepitant records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Enzyme Therapy

What is Enzyme Therapy?

  • Digestive support
  • Bloating and gas
  • Lactose or food intolerance
  • Pancreatic insufficiency
  • Inflammation and recovery
  • Immune support

Enzyme therapy uses supplemental enzymes to help break down food or, in some cases, to support other body processes. There is solid evidence for prescription enzymes in conditions like pancreatic insufficiency and lactose intolerance, but evidence for over-the-counter 'systemic' enzyme products is weak for most claims. Talk with your pharmacist or doctor before starting, especially if you have a chronic health condition.

Enzymes derived from plant, animal, fungal, or microbial sources · Capsules, tablets, chewables, powders, enteric-coated formulations

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

Enzyme Therapy: dosing

There is no single standard dose for enzyme therapy, because the right amount depends on the specific enzyme, the product strength, and the reason for use.For prescription pancreatic enzymes, dosing is set by a doctor and is often based on body weight and fat intake. Do not exceed the dose on the label without medical advice.
