Drug & supplement interaction

Rose Hip + 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 Rose Hip 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.

Interaction report

Rose Hip 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 Rose Hip 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.

Rose Hip safety at a glance

Rose Hip overall Use caution Generally well tolerated as a food, but supplement safety is less studied.
Pregnancy Use caution Food amounts are likely fine, but avoid concentrated supplements unless your doctor approves.
Breastfeeding Use caution Not enough reliable safety data on supplement doses, so use caution.

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

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. Rose Hip has documented interactions with 8 drug classes — the most serious being alkylating agents (moderate), aluminum (moderate) and anticoagulant/antiplatelet drugs (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.

What to actually watch for

No Interaction Found — But Data Suggests Rose Hip 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. One of them is worth acting on rather than waiting out — marked below.

Effects for Orlistat come from the ADVERSE REACTIONS section of its FDA label; effects for Rose Hip 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.

Overlapping uses

What Orlistat Is Prescribed For, and What Rose Hip Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Orlistat is a prescription medicine with approved uses on its FDA label. Rose Hip is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Orlistat is prescribed for: Xenical and prescription-strength orlistat are approved to help obese adults lose weight and keep it off when used with a reduced-calorie diet. They are intended for people with a body mass index (BMI) of 30 or higher, or 27 or higher if other risk factors such as high blood pressure, diabetes, or dyslipidemia (abnormal cholesterol or fat levels in the blood) are present. Alli is the over-the-counter version, approved for weight loss in overweight adults 18 and older when used with a reduced-calorie, low-fat diet and exercise program.

Rose Hip has been studied for:

  • Diabetes studied, not established Rose Hip has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Rose Hip for diabetes

    Although there has been interest in using oral rose hip for diabetes, there is insufficient reliable information about the clinical effects of rose hip for this condition.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Orlistat on your own; if you are taking Rose Hip for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Orlistat

This page covers Rose Hip only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Orlistat page lists 18 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Fish Oil (moderate) and Glucomannan (moderate).

By severity: 1 major · 8 moderate · 9 minor.

From our pharmacist’s overview on the Orlistat page

“People who take Orlistat (Xenical, Alli) for weight loss often browse the very supplement aisle where fiber products and fish oil sit, and both show up on this page, so it deserves genuine attention before you mix anything in. Nearly all 18 ingredients on file can change how oral medications absorb from the gut, and the single major-ra…”

About Rose Hip

What is Rose Hip?

Rose Hip
  • Joint pain and osteoarthritis
  • Colds and flu
  • Source of vitamin C
  • Digestive complaints
  • Anti-inflammatory support

Rose hip is the vitamin C–rich fruit of the wild rose, used traditionally for colds and joint pain. A standardized rose hip powder has some research support for easing osteoarthritis symptoms, but evidence for most other uses is limited. It is generally well tolerated as a food, but talk with your pharmacist or doctor before using it as a supplement.

Rosa canina · Rosaceae · Fruit (hips), including the seeds and outer flesh · Tea, capsules, tablets, powder, syrup, dried fruit, extracts

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

Rose Hip: dosing

There is no single official dose for rose hip. The amount used in osteoarthritis research has been a standardized powder taken daily, but products on the market vary widely in strength and vitamin C content.The best approach is to follow the directions on the product label and not exceed the recommended amount.

Pharmacist Counseling Corner

Taking Rose Hip and Orlistat Together: Common Questions

Is it safe to take Rose Hip with Orlistat?
We do not list a known interaction between Rose Hip 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 Rose Hip and Orlistat have any of the same side effects?
Yes — our sources link each of them separately to 8 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.
Are Rose Hip and Orlistat used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Rose Hip in each. That is a conversation for your prescriber, especially if Orlistat is being adjusted to a target.
How was the Rose Hip and Orlistat combination checked?
Interactions in our licensed database are recorded against drug classes. Orlistat is filed under 2 classifications, and Rose Hip has documented interactions with 8 drug classes — 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 Rose Hip interact with any other medications?
Yes. Rose Hip has 213 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 — Rose Hip is not one of them. The Orlistat interaction page linked on this page lists every one, ranked by severity.
