Drug & supplement interaction

Levilactobacillus Brevis + Pimozide

Pimozide brand name: Orap.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Levilactobacillus Brevis 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. 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.

Levilactobacillus Brevis 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 Levilactobacillus Brevis 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.

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.

How we checked

Why No Interaction Is Listed for Pimozide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Pimozide is filed under 6 classifications — including antipsychotic drugs, qt interval-prolonging drugs, anticholinergic drugs. Levilactobacillus Brevis has documented interactions with 1 drug class — the most serious being antibiotic drugs (moderate) — and none of Pimozide’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

No Interaction Found — But Data Suggests Levilactobacillus Brevis and Pimozide May Share Several of the Same Side Effects

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.

    Pimozide

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

Reported for Levilactobacillus Brevis but not commonly for Pimozide: a higher chance of infection.

Effects for Pimozide come from the ADVERSE REACTIONS section of its FDA label; effects for Levilactobacillus Brevis come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 464 voluntary FDA FAERS reports for Pimozide 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.

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 Levilactobacillus Brevis

What is Levilactobacillus Brevis?

  • Digestive health
  • Gut microbiome support
  • Immune support
  • Oral and dental health
  • Vaginal health

Levilactobacillus brevis (formerly Lactobacillus brevis) is a lactic acid bacterium found in fermented foods like sauerkraut, pickles, and kimchi, and is used as a probiotic. Early research suggests possible benefits for gut and immune health, but strong human evidence is still limited. It is generally well tolerated in healthy people, but anyone with a weakened immune system or serious illness should talk to a doctor first.

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

Levilactobacillus Brevis: dosing

There is no official standardized dose for Levilactobacillus brevis. Probiotic amounts are usually measured in colony-forming units (CFU), and products vary widely in strength and strain.The best approach is to follow the directions on the product label.

Taking Levilactobacillus Brevis and Pimozide Together: Common Questions

Is it safe to take Levilactobacillus Brevis with Pimozide?

Pimozide is filed under 6 classifications, and Levilactobacillus Brevis has documented interactions with 1 drug class — none of Pimozide's classifications are among them.
