Drug & supplement interaction

Graviola + Amlodipine

Amlodipine brand name: Norliqva.

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 Graviola 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. 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

Graviola 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 Graviola 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 Amlodipine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Amlodipine is filed under 5 classifications — including calcium channel blockers, antihypertensive drugs, cytochrome p450 3a4 (cyp3a4) substrates. Graviola has documented interactions with 1 drug class — the most serious being carbamazepine (tegretol) (moderate) — and none of Amlodipine’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.

No Interaction Found — But Data Suggests Graviola and Amlodipine May Share a Side Effect

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.

About Graviola

What is Graviola?

  • Cancer support (unproven)
  • Infections
  • Inflammation
  • High blood pressure
  • Digestive complaints
  • Diabetes

Graviola (soursop) is a tropical fruit tree whose leaves, fruit, and bark are used in traditional medicine, especially in parts of South America, Africa, and Asia. Despite popular online claims that it fights cancer, there is no reliable human evidence that it treats or cures any disease, and animal research raises concerns that it may harm nerve cells. Talk with your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Annona muricata · Annonaceae · Leaves, fruit, bark, seeds, and roots · Tea, capsules, tinctures, fruit pulp, and juice

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

Graviola: dosing

There is no established or standardized safe dose of graviola. Products vary widely in strength and in which plant part they contain.If you choose to use a graviola product, follow the directions on the label, do not exceed the recommended amount, and avoid long-term daily use.

Taking Graviola and Amlodipine Together: Common Questions

Is it safe to take Graviola with Amlodipine?
We do not list a known interaction between Graviola and Amlodipine. 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 Graviola and Amlodipine have any of the same side effects?
Yes — our sources link each of them separately to one 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 Graviola and Amlodipine combination checked?
Interactions in our licensed database are recorded against drug classes. Amlodipine is filed under 5 classifications, and Graviola has documented interactions with 1 drug class — none of Amlodipine'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 Graviola interact with any other medications?
Yes. Graviola has 1 documented drug interaction in our database — Amlodipine 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 Amlodipine interact with any supplements?
Yes. Amlodipine has documented interactions with 232 supplements in our database — Graviola is not one of them. The Amlodipine interaction page linked on this page lists every one, ranked by severity.
