The bottom line No known interaction

We found no known interaction between Goldthread and Eplerenone 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.

Goldthread and Eplerenone

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 Eplerenone and Goldthread 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 Eplerenone

Interactions in our licensed database are recorded against drug classes, not just single drug names. Eplerenone is filed under 2 classifications — antihypertensive drugs, oral drugs. Goldthread has documented interactions with 2 drug classes — the most serious being cyclosporine (neoral, sandimmune) (moderate) and cytochrome p450 3a4 (cyp3a4) substrates (moderate) — and none of Eplerenone’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

What Eplerenone’s Own FDA Label Lists

This is not an interaction — none of it involves Goldthread. These are the most notable effects listed in the ADVERSE REACTIONS section of Eplerenone’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 8 of them are worth acting on rather than waiting out — marked below.

  • Heart failure Worth acting on mentioned in 7.6% of FDA reports for Eplerenone
  • High potassium Worth acting on
  • Low potassium Worth acting on
  • A heart attack Worth acting on
  • Kidney problems Worth acting on mentioned in 7.4% of FDA reports for Eplerenone
  • Chest pain Worth acting on
  • Raised blood pressure Worth acting on
  • Bleeding or bruising Worth acting on
  • Breast tenderness
  • Dizziness mentioned in 5.3% of FDA reports for Eplerenone

Showing the 10 most notable of 13 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Eplerenone. Read the label on DailyMed › Where a percentage is shown, it is the share of 12,732 voluntary FDA FAERS reports for Eplerenone that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Goldthread’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Goldthread side to compare — that is a limit of the record, not a statement that Goldthread has no side effects.

Special populations

Goldthread in Pregnancy & Breastfeeding

Pregnancy Likely Unsafe

When used orally. Berberine is thought to cross the placenta and may cause harm to the fetus. Kernicterus has developed in newborn infants exposed to berberine. Preliminary evidence suggests that maternal intake of goldthread during the first trimester increases the risk of congenital malformations of the central nervous system.

Lactation Likely Unsafe

When used orally. Berberine and other harmful constituents can be transferred to the infant through breast milk.

About Goldthread

What is Goldthread?

Goldthread
  • Digestive upset and diarrhea
  • Mouth sores and sore throat
  • Inflammation
  • Antimicrobial (fighting germs)
  • Blood sugar support
  • Skin and eye complaints

Goldthread is a traditional Chinese and East Asian herb whose root is rich in berberine, a compound being studied for blood sugar, cholesterol, and antimicrobial effects. Strong human evidence for goldthread itself is limited, and it should be avoided in pregnancy and breastfeeding. Talk with your pharmacist or doctor before using it, especially if you take other medicines.

Coptis chinensis · Ranunculaceae · Root and rhizome (the underground stem) · Dried root, powder, capsules, tinctures, teas, and topical preparations

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

Goldthread: dosing

There is no well-established standard dose for goldthread. Products differ widely in how they are made and how much active compound they contain, so it is hard to recommend a single safe amount.The best approach is to follow the directions on the product label and not exceed them.

About Eplerenone

What Is Eplerenone Used For?

Eplerenone treats two conditions. First, it is used to lower high blood pressure (hypertension) in adults. Lowering blood pressure reduces the risk of stroke and heart attack. It can be used alone or alongside other blood pressure medicines.

Second, eplerenone is used to improve survival in stable adults who have heart failure with reduced ejection fraction (HFrEF) — meaning the heart pumps less blood than normal — following an acute myocardial infarction (heart attack).

Most-Reported Side Effects for Eplerenone

From FAERS, the FDA’s public side-effect reporting system (12,732 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Dyspnea 1,138 reports
Cardiac failure 966 reports
