The bottom line No known interaction

We found no known interaction between Cereus and Terbutaline 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 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

Cereus and Terbutaline

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 Terbutaline and Cereus 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 Terbutaline

Interactions in our licensed database are recorded against drug classes, not just single drug names. Terbutaline is filed under 2 classifications — beta-adrenergic agonists, oral drugs. Cereus has documented interactions with 2 drug classes — the most serious being digoxin (lanoxin) (moderate) and monoamine oxidase inhibitors (maois) (moderate) — and none of Terbutaline’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 Cereus and Terbutaline 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.

  • Vomiting / Nausea Additional detail

    Cereus

    “Orally, fresh cereus juice may cause burning of the mouth, queasiness, nausea, vomiting, and diarrhea (4,18).

    Topically, it may cause itching and skin pustules (18).”

About Cereus

What is Cereus?

  • Heart palpitations
  • Mild heart symptoms
  • Anxiety and nervous tension
  • Shortness of breath
  • Fluid retention

Cereus (often called night-blooming cereus) is a cactus traditionally used in folk and homeopathic medicine for heart-related complaints like palpitations. High-quality human evidence supporting these uses is lacking, and because it may affect the heart, it should be used only under medical guidance. Pregnant and breastfeeding people should avoid it.

Selenicereus grandiflorus · Cactaceae · Flowers and young stems · Tincture, liquid extract, capsules, homeopathic preparations

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

Cereus: dosing

There is no established standard dose of Cereus. Products vary widely in strength, and homeopathic preparations are very different from herbal tinctures.If you choose to use a Cereus product, follow the directions on the label and do not exceed them.

From our Cereus monograph — the full record covers uses, side effects and every documented interaction.

About Terbutaline

What Is Terbutaline Used For?

Brand names: Bricanyl, Brethine, Bricanyl Injection, Bricanyl Turbohaler

Terbutaline Sulfate — available as both a tablet and a subcutaneous (under-the-skin) injection — is used to prevent and reverse bronchospasm (sudden tightening of the airways) in adults and children 12 years and older. It is indicated for people with asthma and for reversible bronchospasm associated with bronchitis and emphysema.

Both Terbutaline Sulfate Tablets and Terbutaline Sulfate Injection share these approved uses. The injection form acts more quickly and is given by a healthcare provider under the skin, while the tablet form is taken by mouth on a regular schedule during waking hours.

Taking Cereus and Terbutaline Together: Common Questions

Is it safe to take Cereus with Terbutaline?
We do not list a known interaction between Cereus and Terbutaline. 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 Cereus and Terbutaline 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.
How was the Cereus and Terbutaline combination checked?
Interactions in our licensed database are recorded against drug classes. Terbutaline is filed under 2 classifications, and Cereus has documented interactions with 2 drug classes — none of Terbutaline'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 Cereus interact with any other medications?
Yes. Cereus has 10 documented drug interactions in our database — Terbutaline 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 Terbutaline interact with any supplements?
Yes. Terbutaline has documented interactions with 32 supplements in our database — Cereus is not one of them. The Terbutaline interaction page linked on this page lists every one, ranked by severity.
