The bottom line No known interaction

We found no known interaction between Pao Pereira and Ivabradine 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 Ivabradine states a food rule worth keeping to.

Pao Pereira and Ivabradine

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 Ivabradine and Pao Pereira 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 Pao Pereira at all — not against Ivabradine, 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 Ivabradine’s Own FDA Label Lists

This is not an interaction — none of it involves Pao Pereira. These are the most notable effects listed in the ADVERSE REACTIONS section of Ivabradine’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
  • Heart failure Worth acting on
  • Fainting Worth acting on
  • An irregular heartbeat Worth acting on
  • Raised blood pressure Worth acting on
  • A severe allergic reaction Worth acting on
  • Hives Worth acting on
  • Blurred vision
  • A fast or pounding heartbeat
  • Low blood pressure

Showing the 10 most notable of 13 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

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

How to take them

Some Ivabradine Products Have a Food Rule — Pao Pereira Should Not Break It

At least one FDA label for a product containing Ivabradine says to take it with food. If you take Pao Pereira on an empty stomach out of habit, keep them separate — and take Ivabradine 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 Ivabradine 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.

DOSAGE AND ADMINIST R ATION Adult and pediatric patients greater than 40 kg Starting dose is 2.5 (pediatrics and vulnerable adults) or 5 mg twice daily with food.

From the Dosage and Administration section of the FDA label we read for Ivabradine — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

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.

About Pao Pereira

What is Pao Pereira?

  • Immune support
  • Cancer support (complementary use)
  • Antimalarial/fever (traditional)
  • Digestive complaints (traditional)
  • General tonic

Pao Pereira is a bark extract from a South American tree that is marketed mainly as a complementary cancer and immune-support supplement. Human evidence is very limited, and most research comes from laboratory and animal studies, so it should not be used in place of proven medical care. Talk with your pharmacist or doctor before trying it, especially if you have a serious health condition.

Geissospermum laeve · Apocynaceae · Bark (and bark extract) · Capsules, tinctures, liquid extracts, powdered bark

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

Pao Pereira: dosing

There is no established or standardized dose for Pao Pereira. Different products contain different amounts and strengths of bark extract.If you choose to use it, follow the directions on the product label and do not exceed the recommended amount.

About Ivabradine

What Is Ivabradine Used For?

Brand names: Procoralan, Coralan, Corlentor, Corlanor

Ivabradine is used for stable, symptomatic chronic heart failure in adults to reduce the risk of being hospitalized for worsening heart failure. It is for adults with a reduced ejection fraction (the heart's pumping strength is low, 35% or less), who are in normal sinus rhythm with a resting heart rate of 70 beats per minute or higher. They must also be on the highest beta-blocker dose they can tolerate, or be unable to take beta-blockers.

Corlanor (the brand) is also approved to treat stable, symptomatic heart failure due to dilated cardiomyopathy (a weakened, enlarged heart muscle) in children 6 months and older who are in sinus rhythm with an elevated heart rate. The generic ivabradine tablet labels list the adult use only.
