Drug & supplement interaction

Madder + 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 Madder 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.

Madder 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 Madder 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 Madder at all — not against Rosuvastatin, 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 Madder and Rosuvastatin 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.

    Rosuvastatin

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

Reported for Madder but not commonly for Rosuvastatin: sweating.

Effects for Rosuvastatin come from the ADVERSE REACTIONS section of its FDA label; effects for Madder 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.

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 Madder

What is Madder?

  • Kidney and bladder stones
  • Urinary tract complaints
  • Menstrual problems
  • Natural red dye for fabric
  • Traditional digestive remedy

Madder is a plant whose root has long been used as a red dye and in traditional medicine, mostly for kidney and urinary problems. There is very little reliable human evidence that it works, and some of its compounds have raised concerns about possible cancer-causing effects, so it is generally not recommended for use as a supplement. Talk to your pharmacist or doctor before considering it.

Rubia tinctorum · Rubiaceae · Root · Dried root, powder, capsules, tea, extracts, and natural dye

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

Madder: dosing

There is no established safe or effective dose of madder for any health condition. In general, we do not recommend taking madder root internally. Its safer, well-established use is as a fabric dye rather than as a supplement.

From our Madder monograph — the full record covers uses, side effects and every documented interaction.

About Rosuvastatin

What Is Rosuvastatin Used For?

Brand names: Crestor, Ezallor

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. 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.

Most-Reported Side Effects for Rosuvastatin

From FAERS, the FDA’s public side-effect reporting system (229,715 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 14,778 reports
Nausea 12,432 reports
Dyspnea 11,981 reports

Taking Madder and Rosuvastatin Together: Common Questions

Is it safe to take Madder with Rosuvastatin?
We do not list a known interaction between Madder 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 Madder and Rosuvastatin 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.
Does Rosuvastatin interact with any supplements?
Yes. Rosuvastatin has documented interactions with 63 supplements in our database — Madder is not one of them. The Rosuvastatin interaction page linked on this page lists every one, ranked by severity.
