Jambolan and Durvalumab

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 Durvalumab and Jambolan 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.

Jambolan safety at a glance

Jambolan overall Use caution The fruit is widely eaten as food, but concentrated supplement doses are not well studied.
Pregnancy Avoid Not enough safety data for medicinal amounts, so avoid supplements during pregnancy.
Breastfeeding Avoid Safety while breastfeeding is unknown, so it is best avoided in supplement form.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Durvalumab

Interactions in our licensed database are recorded against drug classes, not just single drug names. Durvalumab is filed under 2 classifications — antineoplastics, immunosuppressants. Jambolan has documented interactions with 3 drug classes — the most serious being antidiabetes drugs (moderate), cytochrome p450 2c9 (cyp2c9) substrates (moderate) and sitagliptin (januvia) (minor) — and none of Durvalumab’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 Durvalumab’s Own FDA Label Lists

This is not an interaction — none of it involves Jambolan. These are the most notable effects listed in the ADVERSE REACTIONS section of Durvalumab’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. 10 of them are worth acting on rather than waiting out — marked below.

  • Low magnesium Worth acting on
  • A change in thyroid levels Worth acting on
  • A stroke or mini-stroke Worth acting on
  • Pain or burning when passing urine Worth acting on
  • Trouble swallowing Worth acting on
  • Bleeding in the gut Worth acting on
  • High potassium Worth acting on
  • Low sodium Worth acting on
  • Low potassium Worth acting on
  • A heart attack Worth acting on

Showing the 10 most notable of 58 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 Durvalumab. Read the label on DailyMed › Where a percentage is shown, it is the share of 20,225 voluntary FDA FAERS reports for Durvalumab that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Jambolan’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Jambolan side to compare — that is a limit of the record, not a statement that Jambolan has no side effects.

From our pharmacist’s overview on the Durvalumab page

“Nearly everything on this page interacts with durvalumab (Imfinzi) for the same underlying reason, immune stimulation. Durvalumab is a cancer immunotherapy, and because the treatment works through the immune system itself, supplements that push immune activity in their own direction (echinacea, ashwagandha, astragalus, and dozens of si…”

About Jambolan

What is Jambolan?

  • Blood sugar support
  • Digestive upset and diarrhea
  • Sore throat and mouth health
  • Antimicrobial
  • General antioxidant support

Jambolan (Syzygium cumini), also called Java plum or black plum, is a tropical fruit tree traditionally used for blood sugar and digestive complaints. Human evidence for these uses is limited and not strong, so it should not replace proven treatments like diabetes medication. The fruit is safe as food, but talk to your pharmacist or doctor before using concentrated supplements.

Syzygium cumini · Myrtaceae · Seeds, fruit, leaves, and bark · Dried seed powder, capsules, tea, fruit extract, juice

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

Jambolan: dosing

There is no well-established standardized dose for Jambolan supplements. Traditional use and products vary widely in the part used (seed, fruit, leaf, or bark) and in how concentrated they are.Because a proven safe and effective dose has not been set, the best approach is to follow the directions on the product label and not exceed them.
