The bottom line No known interaction

We found no known interaction between Ipecac and Propranolol 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.

Interaction report

Ipecac and Propranolol

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 Propranolol and Ipecac 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.

Ipecac safety at a glance

Ipecac overall Avoid No longer recommended for home or routine use due to risk of serious harm and lack of proven benefit.

Breastfeeding Avoid Safety is not established, so it should be avoided while breastfeeding.

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Propranolol

Interactions in our licensed database are recorded against drug classes, not just single drug names. Propranolol is filed under 9 classifications — including beta-blockers, cytochrome p450 2c19 (cyp2c19) substrates, antihypertensive drugs. Ipecac has documented interactions with 1 drug class — the most serious being activated charcoal (major) — and none of Propranolol’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.

What Ipecac Itself Has Been Linked To

This is not an interaction — nothing below involves Propranolol. It is the side-effect record for Ipecac on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Ipecac, this list is the first place to look. 4 entries are worth acting on rather than waiting out — marked below.

  • Muscle weakness / Heart failure Worth acting on Additional detail

    “Orally, ipecac can cause hypotension, dyspnea, and tachycardia (11,56440). Chronic use is associated with cardiac myopathy and death related to heart failure (6,18,56391,56409,56424,56467). Overdose is associated with shock and cardiac arrhythmias (18).

    Intravenously, ipecac in total doses over 1 gram can lead to circulatory collapse (6).”

See Every Supplement That Interacts With Propranolol

This page covers Ipecac only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Propranolol page lists 236 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), American Hellebore (major), American Mistletoe (major), Indian Snakeroot (major) and Tyramine (major).

By severity: 5 major · 194 moderate · 37 minor.

From our pharmacist’s overview on the Propranolol page

“Propranolol (Inderal) slows the heart and lowers blood pressure, which is exactly why its 236-ingredient interaction list deserves genuine care. Five entries rate major, and those are the ones to understand first.”

About Ipecac

What is Ipecac?

  • Inducing vomiting after poisoning (historical)
  • Cough and chest congestion (expectorant)
  • Nausea and vomiting (homeopathic use)
  • Amebic dysentery (historical)

Ipecac comes from the root of a South American plant and was once widely used as syrup of ipecac to make people vomit after swallowing poison. Medical groups no longer recommend it for poisoning because it is not proven helpful and can be dangerous, and misuse has caused serious harm. There is no safe, established home use for ipecac today, and you should call Poison Control rather than reach for it.

Carapichea ipecacuanha · Rubiaceae · Dried root and rhizome · Syrup (syrup of ipecac), tincture, liquid extract, homeopathic preparations

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

Ipecac: dosing

There is no recommended over-the-counter dose for ipecac because it is no longer advised for home use. We will not provide dosing amounts here, since using ipecac on your own can be harmful.If you have a product on hand, do not use it for poisoning—instead, call your Poison Control center or emergency services right away, as they can give the safest, up-to-date advice.For any homeopathic ipecac product, follow the directions on the label, but be aware these products are not proven to work.

About Propranolol (Cardiovascular)

What Is Propranolol (Cardiovascular) Used For?

Brand names: Inderal LA, Inderal, Angilol, Syprol, Inderal Injection, Half-Inderal LA, Bedranol SR, Half Beta Prograne, Beta Prograne, Lopranol LA, Slo-Pro, InnoPran XL

This intravenous (IV) form of propranolol is used in hospital or clinical settings to treat dangerous heart rhythm problems. It is generally reserved for life-threatening arrhythmias (abnormal heart rhythms) or those that occur during anesthesia.

Specific conditions it treats include fast heart rates coming from the upper chambers of the heart (supraventricular tachycardia), certain arrhythmias caused by digitalis toxicity, dangerous ventricular rhythms that haven't responded to other treatments, and fast heart rates caused by excess adrenaline-like substances during surgery.
