The bottom line No known interaction

We found no known interaction between Figwort and Flecainide 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.

Figwort and Flecainide

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 Flecainide and Figwort 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 Flecainide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Flecainide is filed under 4 classifications — including qt interval-prolonging drugs, cytochrome p450 2d6 (cyp2d6) substrates, oral drugs. Figwort has documented interactions with 2 drug classes — the most serious being diuretic drugs (moderate) and lithium (moderate) — and none of Flecainide’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.

From the ADVERSE REACTIONS section of the FDA label for Flecainide.

About Figwort

What is Figwort?

  • Skin conditions like eczema and psoriasis
  • Minor wounds and rashes
  • Swelling and inflammation
  • Mild constipation
  • Traditional 'detox' or lymphatic support

Figwort is a traditional herb used mainly for skin problems and minor swelling, but solid human studies are lacking, so its benefits remain unproven. It is generally used short-term and topically, and people with heart conditions, pregnant women, and nursing mothers should avoid it until more is known.

Scrophularia nodosa · Scrophulariaceae · Aerial parts (leaves, stems, flowers) and sometimes the root · Tea, tincture, capsules, dried herb, topical creams or ointments

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

Figwort: dosing

There is no established standardized dose for figwort. Traditional use varies by the form (tea, tincture, capsule, or ointment) and by the product maker. Avoid using more than the label suggests, and do not use it for long periods without professional advice.

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

About Flecainide

What Is Flecainide Used For?

Brand name: Tambocor

Flecainide Acetate tablets are used to prevent episodes of certain abnormal heart rhythms. In patients without structural heart disease, it is approved to prevent paroxysmal supraventricular tachycardia (PSVT — episodes of rapid heart rate starting above the ventricles) and paroxysmal atrial fibrillation/flutter (PAF — intermittent episodes of irregular, rapid heart rhythm in the upper chambers), when these cause disabling symptoms.

Flecainide Acetate tablets are also used to prevent life-threatening ventricular arrhythmias — dangerous rapid rhythms starting in the lower chambers of the heart, such as sustained ventricular tachycardia. It is not recommended for less serious ventricular arrhythmias, for patients with a recent heart attack, or for chronic (ongoing, persistent) atrial fibrillation.
