The bottom line No known interaction

We found no known interaction between Sundew and Digoxin 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.

Sundew and Digoxin

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 Digoxin and Sundew 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 Sundew at all — not against Digoxin, 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.

Sundew safety at a glance

Sundew overall Use caution Generally used in small traditional amounts, but human safety data are limited.
Pregnancy Avoid Not enough safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid Not enough safety information, so it is best avoided while breastfeeding.

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

What Digoxin’s Own FDA Label Lists

This is not an interaction — none of it involves Sundew. These are the most notable effects listed in the ADVERSE REACTIONS section of Digoxin’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. 7 of them are worth acting on rather than waiting out — marked below.

  • A slow heartbeat Worth acting on
  • Hallucinations Worth acting on
  • Heart failure Worth acting on
  • An irregular heartbeat Worth acting on
  • Confusion Worth acting on
  • Low mood Worth acting on
  • A low platelet count Worth acting on
  • Breast tenderness
  • Blurred vision
  • A fast or pounding heartbeat

From the ADVERSE REACTIONS section of the FDA label for Digoxin. Read the label on DailyMed › Sundew’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Sundew side to compare — that is a limit of the record, not a statement that Sundew has no side effects.

From our pharmacist’s overview on the Digoxin page

“Digoxin is a heart medicine with a narrow therapeutic index, meaning the gap between a helpful blood level and a harmful one is small, and few drugs give me more pause when supplements enter the picture. The most serious entries here are herbs that themselves contain digoxin-like cardiac glycosides, foxglove and lily-of-the-valley amon…”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Sundew is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Sundew reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified October 4, 2026. The Sundew and Digoxin records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Sundew

What is Sundew?

  • Cough
  • Bronchitis
  • Whooping cough
  • Asthma-related symptoms
  • Sore throat
  • Spasmodic dry cough

Sundew is a small carnivorous plant used traditionally as a cough and respiratory remedy, often in combination cough syrups and homeopathic products. Modern human evidence for its effectiveness is very limited, so it should be seen as a traditional remedy rather than a proven treatment. Talk to your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or giving it to a child.

Drosera rotundifolia · Droseraceae · Whole flowering plant (aerial parts) · Tincture, tea, syrup, capsules, homeopathic preparations, lozenges

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

Sundew: dosing

There is no well-established standardized dose for sundew. It is usually taken as part of a tincture, tea, syrup, lozenge, or homeopathic product, and the amount varies widely from product to product.The safest approach is to follow the directions on the product label and not exceed the recommended amount.

About Digoxin

What Is Digoxin Used For?

Brand names: Lanoxicaps, Lanoxin, Digitek

Digoxin treats mild to moderate heart failure in adults. It improves heart failure symptoms and exercise capacity, and it reduces heart failure-related hospitalizations and emergency care. It does not change survival.

It also helps control the resting heart rate in adults with chronic atrial fibrillation (an irregular heartbeat). In children with heart failure, the tablet, oral solution and most injection products are used to increase the heart’s pumping strength (myocardial contractility). Some older injection labels list only the adult uses. Digoxin Oral Solution should not be used for multifocal atrial tachycardia.
