Fumitory and Trandolapril, Verapamil

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 Trandolapril, Verapamil and Fumitory 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 Fumitory at all — not against Trandolapril, Verapamil, 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.

How to take them

Some Trandolapril, Verapamil Products Have a Food Rule — Fumitory Should Not Break It

At least one FDA label for a product containing Trandolapril, Verapamil says to take it with food. If you take Fumitory on an empty stomach out of habit, keep them separate — and take Trandolapril, Verapamil with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Trandolapril, Verapamil products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Trandolapril and verapamil hydrochloride extended-release tablets should be administered with food.

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

From our pharmacist’s overview on the Trandolapril, Verapamil page

“This is one of the supplement lists I would want a patient to read closely, not skim. Tarka combines trandolapril and verapamil to lower blood pressure, and most of these interactions pull on that same lever, either dropping pressure further than intended or working against the medicine altogether.”

About Fumitory

What is Fumitory?

  • Digestive and bile-flow complaints
  • Mild liver and gallbladder support
  • Skin conditions like eczema
  • Mild constipation
  • Cleansing or 'detox' tonics

Fumitory is a traditional European herb used mainly for digestive and minor liver or gallbladder complaints, but solid human evidence is very limited. It may cause side effects at higher doses, and its safety is not well established, so talk with your pharmacist or doctor before using it and avoid it during pregnancy and breastfeeding.

Fumaria officinalis · Papaveraceae · Aerial parts (flowering tops, leaves, and stems) · Tea, dried herb, liquid extract, tincture, capsules

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

Fumitory: dosing

There is no well-established standardized dose for Fumitory. Traditional use involves teas or liquid extracts made from the dried herb, but exact amounts vary widely between products.Because a reliable, evidence-based dose has not been set, the safest approach is to follow the directions on the product label and not exceed them.
