Purple Loosestrife and Defibrotide Sodium

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 Defibrotide Sodium and Purple Loosestrife 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Purple Loosestrife at all — not against Defibrotide Sodium, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

What Defibrotide Sodium’s Own FDA Label Lists

This is not an interaction — none of it involves Purple Loosestrife. These are the most notable effects listed in the ADVERSE REACTIONS section of Defibrotide Sodium’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. 4 of them are worth acting on rather than waiting out — marked below.

  • Kidney problems Worth acting on
  • Bleeding or bruising Worth acting on
  • A higher chance of infection Worth acting on
  • An allergic reaction Worth acting on
  • Low blood pressure
  • Diarrhea
  • Vomiting
  • Nausea

From the ADVERSE REACTIONS section of the FDA label for Defibrotide Sodium. Read the label on DailyMed › Purple Loosestrife’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Purple Loosestrife side to compare — that is a limit of the record, not a statement that Purple Loosestrife has no side effects.

From our pharmacist’s overview on the Defibrotide Sodium page

“Defibrotide (Defitelio) is an intravenous drug for severe veno-occlusive disease of the liver after a stem cell transplant, and part of how it works is by reducing the blood's tendency to clot. That makes bleeding the single thread running through this entire list, and it deserves real care.”

About Purple Loosestrife

What is Purple Loosestrife?

  • Diarrhea
  • Digestive upset
  • Minor wound care
  • Sore throat and mouth irritation
  • Menstrual-related complaints

Purple Loosestrife is a flowering wetland plant traditionally used for diarrhea and minor digestive or skin complaints, largely because of its astringent tannin content. Modern human studies are very limited, so its benefits are not well proven. If you are considering it, talk with your pharmacist or doctor first, and avoid it during pregnancy and breastfeeding.

Lythrum salicaria · Lythraceae · Aerial parts (flowering tops, leaves) · Tea, liquid extract, tincture, dried herb

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

Purple Loosestrife: dosing

There is no well-established standardized dose for Purple Loosestrife.
