The bottom line No known interaction

We found no known interaction between Proteolytic Enzymes (proteases) and Pimozide 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.

Proteolytic Enzymes (proteases) and Pimozide

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 Pimozide and Proteolytic Enzymes (proteases) 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 Proteolytic Enzymes (proteases) at all — not against Pimozide, 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.

Proteolytic Enzymes (proteases) safety at a glance

Proteolytic Enzyme... overall Use caution Generally well tolerated for most adults, but may cause digestive upset or allergic reactions.
Pregnancy Avoid Safety has not been established, so it is best avoided during pregnancy unless prescribed.
Breastfeeding Use caution There is little safety data during breastfeeding, so use is not recommended without medical advice.

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

What to actually watch for

What Proteolytic Enzymes (proteases) Itself Has Been Linked To

This is not an interaction — nothing below involves Pimozide. It is the side-effect record for Proteolytic Enzymes (proteases) on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Proteolytic Enzymes (proteases), this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Wheezing Worth acting on Additional detail

    “Proteolytic enzymes are commonly found in laundry detergents and pre-spotter products. Rarely, protease specific IgE positive tests possibly related to these products have occurred. Exposure may be airborne or topical. In addition, in case reports, occupational exposure to the airborne proteolytic enzyme pepsin has resulted in allergic rhinoconjunctivitis or asthma.”

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

See Every Supplement That Interacts With Pimozide

This page covers Proteolytic Enzymes (proteases) only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Pimozide page lists 180 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), American Hellebore (major), Arsenic (major), Cesium (major) and Ephedra (major).

By severity: 12 major · 127 moderate · 41 minor.

From our pharmacist’s overview on the Pimozide page

“Pimozide (Orap), prescribed mainly for severe tics in Tourette syndrome, is a medicine I ask patients to check every supplement against before adding it. Twelve of the 180 ingredients on file rate major, and most of the risk runs through one pathway: 121 of them affect CYP3A4, the enzyme that clears pimozide.”

About Proteolytic Enzymes (proteases)

What is Proteolytic Enzymes (proteases)?

  • Digestion and bloating
  • Muscle soreness and exercise recovery
  • Inflammation and swelling
  • Sinus and respiratory congestion
  • Post-surgery or injury recovery

Proteolytic enzymes are proteins that help break down other proteins, and common examples include bromelain (from pineapple), papain (from papaya), trypsin, chymotrypsin, and pancreatin. People take them for digestion, inflammation, and muscle recovery, but the evidence is mixed and stronger for some uses (like aiding digestion in people who lack natural enzymes) than others. They are generally well tolerated, but talk with a pharmacist or doctor before use, especially if you have allergies, a bleeding risk, or are pregnant.

Enzymes sourced from fruit (pineapple, papaya), animal pancreas, or microbial/fungal fermentation · Capsules, tablets (often enteric-coated), powders

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

Proteolytic Enzymes (proteases): dosing

There is no single standardized dose for proteolytic enzyme supplements. Products vary widely in their source, strength, and how they measure enzyme activity (for example, units may be listed differently from one brand to another).Because of this, the best approach is to follow the directions on the product label and not exceed the recommended amount. Do not assume an over-the-counter product replaces a prescription pancreatic enzyme.

About Pimozide

What Is Pimozide Used For?

Brand name: Orap

Pimozide tablets are used to suppress motor tics (involuntary movements) and phonic tics (involuntary sounds or words) in people with Tourette's Disorder. It is reserved for patients whose daily life or development is severely affected by their tics — it is not intended as a first-line treatment, and it is not used for tics that are mild or mainly cosmetic concerns.

Pimozide is not meant for tics caused by other conditions or medications, and it should not be used for simple tics unrelated to Tourette's Disorder.

Most-Reported Side Effects for Pimozide

From FAERS, the FDA’s public side-effect reporting system (471 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Parkinsonism 42 reports
Weight increased 38 reports
Somnolence 33 reports
Hypotension 29 reports
Neuroleptic malignant syndrome 29 reports
