The bottom line No known interaction

We found no known interaction between Pareira and Amlodipine 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.

Pareira and Amlodipine

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 Amlodipine and Pareira 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 Pareira at all — not against Amlodipine, 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.

What Amlodipine’s Own FDA Label Lists

This is not an interaction — none of it involves Pareira. These are the most notable effects listed in the ADVERSE REACTIONS section of Amlodipine’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. 10 of them are worth acting on rather than waiting out — marked below.

  • Trouble swallowing Worth acting on
  • A slow heartbeat Worth acting on
  • Pancreatitis Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • Heart failure Worth acting on
  • High blood sugar Worth acting on
  • Fainting Worth acting on
  • An irregular heartbeat Worth acting on

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

About Pareira

What is Pareira?

  • Urinary tract complaints
  • Bladder irritation and inflammation
  • Kidney stones
  • Fluid retention (diuretic use)
  • Digestive upset

Pareira is a traditional plant remedy, mainly from the South American vine Chondrodendron tomentosum, that has long been used for urinary and bladder complaints. Modern scientific evidence in humans is very limited, and some related plants in this group contain powerful muscle-relaxing compounds, so it should be used cautiously and only under professional guidance.

Chondrodendron tomentosum · Menispermaceae · Root and woody stem (bark) · Dried root, tincture, fluid extract, homeopathic preparations

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

Pareira: dosing

There is no established standardized dose for pareira, and products vary widely in strength and form. Because of this, it is not possible to recommend a specific safe and effective amount.If you choose to use a pareira product, follow the directions on the label and do not exceed the recommended amount.
