Drug & supplement interaction

Angel's Trumpet + Ibandronate

Ibandronate brand names: Boniva, Boniva IV.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Angel's Trumpet and Ibandronate 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 Ibandronate states a food rule worth keeping to, and the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Angel's Trumpet and Ibandronate

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 Ibandronate and Angel's Trumpet 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.

How we checked

Why No Interaction Is Listed for Ibandronate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ibandronate is filed under 2 classifications — bisphosphonates, oral drugs. Angel's Trumpet has documented interactions with 1 drug class — the most serious being anticholinergic drugs (moderate) — and none of Ibandronate’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 to actually watch for

No Interaction Found — But Data Suggests Angel's Trumpet and Ibandronate May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

How to take them

Some Ibandronate Products Have a Food Rule — Angel's Trumpet Should Not Break It

At least one FDA label for a product containing Ibandronate says to take it on an empty stomach. Most supplements — Angel's Trumpet included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Ibandronate on its own and move Angel's Trumpet to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Ibandronate 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.

2 DOSAGE AND ADMINISTRATION Take one 150 mg tablet once monthly on the same day each month ( 2.1 ) Instruct patient to: ( 2.2 ) Swallow whole tablet with 6 to 8 oz of plain water only, at least 60 minutes before the first food, beverage, or medication of day.

From the Dosage and Administration section of the FDA label we read for Ibandronate — 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.

See Every Supplement That Interacts With Ibandronate

This page covers Angel's Trumpet only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Ibandronate page lists 23 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Calcium (moderate), Coffee Charcoal (moderate), Dolomite (moderate) and European Mandrake (moderate).

By severity: 1 major · 13 moderate · 9 minor.

From our pharmacist’s overview on the Ibandronate page

“Ibandronate (Boniva) treats osteoporosis, and it is famously hard to absorb, which is why you take it fasting with plain water. Nearly all 23 supplements on this list attack that same weak point, so treat them with real care, because the danger is not a new side effect but a dose that quietly never reaches your bones.”

About Angel's Trumpet

What is Angel's Trumpet?

Angel's Trumpet
  • Traditional folk medicine
  • Asthma or breathing remedies (historical)
  • Pain relief (traditional)
  • Recreational hallucinogen (dangerous misuse)
  • Ornamental garden plant

Angel's Trumpet is a highly poisonous ornamental plant that contains powerful toxins like scopolamine and atropine. There is no safe medicinal dose, and even small amounts can cause hallucinations, dangerous heart effects, coma, or death. It should not be taken as a supplement or remedy.

Brugmansia spp. · Solanaceae · Flowers, leaves, seeds, and roots (all parts are toxic) · Ornamental plant; rarely as teas, infusions, or smoked preparations (all unsafe)

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

Angel's Trumpet: dosing

There is no safe or established dose of Angel's Trumpet. The amount of toxin in the plant varies greatly from one plant, flower, or season to another, so even people who think they are using a "small" amount can be seriously poisoned.Because of these dangers, we cannot provide any dosing guidance, and we strongly advise against using this plant in any form.

Taking Angel's Trumpet and Ibandronate Together: Common Questions

Is it safe to take Angel's Trumpet with Ibandronate?
We do not list a known interaction between Angel's Trumpet and Ibandronate. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Angel's Trumpet and Ibandronate have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Should I take Angel's Trumpet and Ibandronate at the same time of day?
At least one FDA label for a product containing Ibandronate says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Ibandronate on its own and move Angel's Trumpet to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
How was the Angel's Trumpet and Ibandronate combination checked?
Interactions in our licensed database are recorded against drug classes. Ibandronate is filed under 2 classifications, and Angel's Trumpet has documented interactions with 1 drug class — none of Ibandronate's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Angel's Trumpet interact with any other medications?
Yes. Angel's Trumpet has 195 documented drug interactions in our database — Ibandronate is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Ibandronate interact with any supplements?
Yes. Ibandronate has documented interactions with 23 supplements in our database — Angel's Trumpet is not one of them. The Ibandronate interaction page linked on this page lists every one, ranked by severity.
