Drug & supplement interaction

Grape + Rosuvastatin

Rosuvastatin brand names: Crestor, Ezallor.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Grape and Rosuvastatin 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

Grape and Rosuvastatin

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 Rosuvastatin and Grape 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 Rosuvastatin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Rosuvastatin is filed under 4 classifications — including hmg-coa reductase inhibitors ("statins"), hepatotoxic drugs, oral drugs. Grape has documented interactions with 9 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), cyclosporine (neoral, sandimmune) (moderate) and cytochrome p450 1a2 (cyp1a2) substrates (moderate) — and none of Rosuvastatin’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 Grape and Rosuvastatin 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. 2 of them are worth acting on rather than waiting out — marked below.

Reported for Grape but not commonly for Rosuvastatin: stomach upset, sore throat, a bowel blockage and hair loss.

Effects for Rosuvastatin come from the ADVERSE REACTIONS section of its FDA label; effects for Grape come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 223,851 voluntary FDA FAERS reports for Rosuvastatin 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 Rosuvastatin Is Prescribed For, and What Grape Has Been Studied For

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

Rosuvastatin is prescribed for: Rosuvastatin tablets are used alongside diet changes to lower LDL-C ("bad" cholesterol), total cholesterol, and triglycerides (blood fats), and to raise HDL-C ("good" cholesterol) in adults with high cholesterol or mixed cholesterol problems. They are also used in adults with very high triglycerides, a condition called primary dysbetalipoproteinemia (Type III, a genetic fat-metabolism disorder), and to slow the buildup of plaque in arteries (atherosclerosis). In people without established heart disease but with multiple risk factors, rosuvastatin tablets can reduce the risk of heart attack, stroke, and procedures to open blocked arteries. For children and teens aged 8 and older with heterozygous familial hypercholesterolemia (HeFH, an inherited high-cholesterol condition), the tablet form is used to lower LDL-C after diet alone has not worked.

Read the rest of what Rosuvastatin is prescribed for

Crestor tablets are also approved to treat homozygous familial hypercholesterolemia (HoFH, a more severe inherited form) in adults and in children aged 7 and older.

Grape has been studied for:

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

    Grape for hypercholesterolemia

    Small clinical studies suggest that oral grape products reduce cholesterol levels by a small amount.

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

    Grape for atherosclerosis

    Oral grape seed extract has only been evaluated in combination with other ingredients; its effect when used alone is unclear.

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

From our pharmacist’s overview on the Rosuvastatin page

“Rosuvastatin (Crestor, Ezallor) is a statin taken daily for years to lower cholesterol, and its supplement list deserves real scrutiny, not a quick skim. Five of the 63 ingredients on file carry a major rating, headed by grapefruit, which can raise statin blood levels, and by heavy drinking, since beer and wine compound the strain this…”

About Grape

What is Grape?

Grape
  • Antioxidant support
  • Heart and circulation health
  • Vein problems (such as varicose veins)
  • Eye health
  • General anti-inflammatory support

Grapes and grape products like grape seed extract contain antioxidant compounds such as resveratrol and proanthocyanidins that may support heart and blood vessel health. While the food is healthy and generally safe, the supplement evidence for treating specific conditions is mostly limited or preliminary. Talk with your pharmacist or doctor before starting a grape supplement.

Vitis vinifera · Vitaceae · Fruit, skin, seed, and leaves · Fresh fruit, juice, wine, capsules, tablets, grape seed extract, and standardized extracts

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

Grape: dosing

There is no single official or proven dose for grape supplements. The right amount can depend on the specific product, the form (such as grape seed extract), and how it is standardized.Because products vary widely in strength, the best approach is to follow the directions on the product label and not exceed the recommended amount. They can help you decide whether a grape supplement is appropriate for you.

Taking Grape and Rosuvastatin Together: Common Questions

Is it safe to take Grape with Rosuvastatin?
We do not list a known interaction between Grape and Rosuvastatin. 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 Grape and Rosuvastatin have any of the same side effects?
Yes — our sources link each of them separately to 10 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 Grape and Rosuvastatin 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 Grape in each. That is a conversation for your prescriber, especially if Rosuvastatin is being adjusted to a target.
How was the Grape and Rosuvastatin combination checked?
Interactions in our licensed database are recorded against drug classes. Rosuvastatin is filed under 4 classifications, and Grape has documented interactions with 9 drug classes — none of Rosuvastatin'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 Grape interact with any other medications?
Yes. Grape has 910 documented drug interactions in our database — Rosuvastatin 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 Rosuvastatin interact with any supplements?
Yes. Rosuvastatin has documented interactions with 63 supplements in our database — Grape is not one of them. The Rosuvastatin interaction page linked on this page lists every one, ranked by severity.
