Drug & supplement interaction

Wild Cherry + Orlistat

Orlistat brand names: Xenical, Alli.

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 Wild Cherry and Orlistat 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.

Wild Cherry and Orlistat

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 Orlistat and Wild Cherry 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 Orlistat

Interactions in our licensed database are recorded against drug classes, not just single drug names. Orlistat is filed under 2 classifications — including oral drugs. Wild Cherry has documented interactions with 1 drug class — the most serious being cytochrome p450 3a4 (cyp3a4) substrates (moderate) — and none of Orlistat’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 Wild Cherry and Orlistat 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.

  • Anxiety or restlessness / Vomiting / Headache / Nausea Additional detail

    Wild Cherry

    “Orally, large amounts of wild cherry can lead to cyanide toxicity, which can be fatal (18,41565). A case of accidental poisoning has been reported for a 56-year old women who consumed approximately 300 grams of wild cherries that had been steeped in alcohol the evening before symptom onset.”

    Orlistat

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

Reported for Wild Cherry but not commonly for Orlistat: a slow heartbeat, confusion, hallucinations and blurred vision.

Effects for Orlistat come from the ADVERSE REACTIONS section of its FDA label; effects for Wild Cherry come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 25,755 voluntary FDA FAERS reports for Orlistat 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.

About Wild Cherry

What is Wild Cherry?

Wild Cherry
  • Cough
  • Bronchitis and respiratory irritation
  • Sore throat
  • Digestive upset and diarrhea
  • Flavoring agent

Wild cherry bark is a traditional cough remedy found in many old-fashioned cough syrups and lozenges, but there is little modern scientific evidence proving it works. The bark, leaves, and seeds naturally contain cyanide-producing compounds, so it should be used only in properly prepared products and avoided in large amounts. Talk with a pharmacist or doctor before using it, especially during pregnancy or for children.

Prunus serotina · Rosaceae · Bark (inner and stem bark), and sometimes fruit and leaves · Syrup, cough lozenges, tea, tincture, dried bark extract

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

Wild Cherry: dosing

There is no well-established standardized dose for wild cherry. Amounts vary widely between different syrups, lozenges, teas, and tinctures.The safest approach is to follow the directions on the product label and not to exceed them. Avoid making concentrated homemade preparations from the bark, leaves, or pits.

Taking Wild Cherry and Orlistat Together: Common Questions

Is it safe to take Wild Cherry with Orlistat?
We do not list a known interaction between Wild Cherry and Orlistat. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Wild Cherry and Orlistat have any of the same side effects?
Yes — our sources link each of them separately to 4 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Wild Cherry and Orlistat combination checked?
Interactions in our licensed database are recorded against drug classes. Orlistat is filed under 2 classifications, and Wild Cherry has documented interactions with 1 drug class — none of Orlistat's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Wild Cherry interact with any other medications?
Yes. Wild Cherry has 643 documented drug interactions in our database — Orlistat is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Orlistat interact with any supplements?
Yes. Orlistat has documented interactions with 18 supplements in our database — Wild Cherry is not one of them. The Orlistat interaction page linked on this page lists every one, ranked by severity.
