Drug & supplement interaction

Plant Sterols + Ramucirumab

Ramucirumab brand name: Cyramza.

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 Plant Sterols and Ramucirumab 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

Plant Sterols and Ramucirumab

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 Ramucirumab and Plant Sterols 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 Plant Sterols at all — not against Ramucirumab, 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

No Interaction Found — But Data Suggests Plant Sterols and Ramucirumab May Share a Side Effect

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.

  • Diarrhea reported in 3.6% of FDA reports for Ramucirumab Additional detail

    Plant Sterols

    “Abdominal discomfort has occurred in one child in a clinical trial of oral plant sterols. Because plant sterols decrease cholesterol absorption in the gut, there is concern that they might produce some gastrointestinal symptoms like diarrhea and excess amounts of fat in the stool (steatorrhea), although these adverse effects have not been reported in clinical research.”

Reported for Plant Sterols but not commonly for Ramucirumab: stomach upset, a skin rash and acne.

Effects for Ramucirumab come from the ADVERSE REACTIONS section of its FDA label; effects for Plant Sterols come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 6,109 voluntary FDA FAERS reports for Ramucirumab 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 Ramucirumab Is Prescribed For, and What Plant Sterols Has Been Studied For

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

Ramucirumab is prescribed for: Cyramza (ramucirumab) injection is used to treat several types of advanced or metastatic cancer in adults. It is used for advanced or metastatic gastric (stomach) cancer or gastro-esophageal junction cancer that has progressed after prior chemotherapy — either alone or combined with paclitaxel. It is also used for metastatic non-small cell lung cancer, either with erlotinib as a first-line treatment for tumors with certain EGFR mutations, or with docetaxel after platinum-based chemotherapy has stopped working. Additionally, Cyramza is used with FOLFIRI chemotherapy for metastatic colorectal cancer that has progressed after certain prior treatments, and as a single agent for hepatocellular carcinoma (a type of liver cancer) in patients who have elevated alpha-fetoprotein levels and have already received sorafenib.

Plant Sterols has been studied for:

  • Colorectal cancer studied, not established Plant Sterols has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Plant Sterols for colorectal cancer

    It is unclear if dietary plant sterols are beneficial for colorectal cancer prevention.

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 Ramucirumab on your own; if you are taking Plant Sterols for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Plant Sterols

What is Plant Sterols?

  • High cholesterol
  • Heart health support
  • Lowering LDL cholesterol

Plant sterols (and their close relatives, plant stanols) are natural compounds found in plants that can modestly lower LDL ('bad') cholesterol when taken regularly in adequate amounts, usually through fortified foods or supplements. They are widely considered a useful add-on to a heart-healthy diet, but they are not a replacement for prescribed cholesterol medicine. Talk with your pharmacist or doctor before starting them, especially if you take cholesterol drugs.

Sterols extracted from plant oils, nuts, seeds, grains, and legumes · Capsules, softgels, fortified margarine/spreads, fortified yogurt and milk, powders

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

Plant Sterols: dosing

There is no single official dose for everyone, but cholesterol-lowering benefits are generally seen only when enough is taken consistently each day, usually spread across meals. Taking them with food is often recommended, since they work by affecting how cholesterol is absorbed during digestion.The best approach is to follow the directions on your specific product label, since fortified foods and supplements vary in strength.

Taking Plant Sterols and Ramucirumab Together: Common Questions

Is it safe to take Plant Sterols with Ramucirumab?
We do not list a known interaction between Plant Sterols and Ramucirumab. 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 Plant Sterols and Ramucirumab have any of the same side effects?
Yes — our sources link each of them separately to one 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 Plant Sterols and Ramucirumab 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 Plant Sterols in each. That is a conversation for your prescriber, especially if Ramucirumab is being adjusted to a target.
