Butea Superba + Trandolapril, Verapamil
Trandolapril, Verapamil brand name: Tarka.
We found no known interaction between Butea Superba and Trandolapril, Verapamil 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 label for Trandolapril, Verapamil states a food rule worth keeping to.
Butea Superba 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 Butea Superba 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.

Why No Interaction Is Listed for Trandolapril, Verapamil

Some Trandolapril, Verapamil Products Have a Food Rule — Butea Superba Should Not Break It
At least one FDA label for a product containing Trandolapril, Verapamil says to take it with food. If you take Butea Superba 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.”
