Rehmannia 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 Rehmannia 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 Defibrotide Sodium

Interactions in our licensed database are recorded against drug classes, not just single drug names. Defibrotide Sodium is filed under a single classification — anticoagulant/antiplatelet drugs. Rehmannia has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and antihypertensive drugs (moderate) — and none of Defibrotide Sodium’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

What Defibrotide Sodium’s Own FDA Label Lists

This is not an interaction — none of it involves Rehmannia. 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 mentioned in 4.4% of FDA reports for Defibrotide Sodium
  • A higher chance of infection Worth acting on
  • An allergic reaction Worth acting on
  • Low blood pressure mentioned in 4.5% of FDA reports for Defibrotide Sodium
  • Diarrhea
  • Vomiting
  • Nausea

From the ADVERSE REACTIONS section of the FDA label for Defibrotide Sodium. Read the label on DailyMed › Where a percentage is shown, it is the share of 3,546 voluntary FDA FAERS reports for Defibrotide Sodium that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Rehmannia’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Rehmannia side to compare — that is a limit of the record, not a statement that Rehmannia 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 Rehmannia

What is Rehmannia?

  • Kidney and adrenal support
  • Anemia and blood building (traditional)
  • Inflammatory conditions
  • Allergies
  • Fatigue and aging-related complaints

Rehmannia is a root used for centuries in Traditional Chinese Medicine, often to 'tonify' the kidneys and support energy or blood health. Human evidence for most modern uses is limited, so it should be viewed as unproven rather than reliable. Talk with a pharmacist or doctor before trying it, especially if you are pregnant, breastfeeding, or take other medicines.

Rehmannia glutinosa · Orobanchaceae · Root (raw or steam-prepared) · Dried root, decoctions/teas, capsules, tinctures, and ingredient in multi-herb formulas

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

Rehmannia: dosing

There is no official, well-established standardized dose for Rehmannia. Traditional use varies widely depending on the form (raw versus prepared root), whether it is a tea, capsule, or tincture, and whether it is part of a larger herbal formula.The safest approach is to follow the directions on the product label and not exceed them.

About Defibrotide Injection

What Is Defibrotide Injection Used For?

Brand name: Defitelio

Defitelio (defibrotide injection) is used to treat hepatic veno-occlusive disease (VOD) — also called sinusoidal obstruction syndrome (SOS) — in adult and pediatric patients. This is a serious condition where small blood vessels in the liver become blocked, most often after a hematopoietic stem-cell transplant (HSCT).

Defitelio is specifically indicated when VOD is accompanied by kidney dysfunction or pulmonary (lung) dysfunction, making it a treatment for one of the most severe forms of this complication.

Most-Reported Side Effects for Defibrotide Sodium

From FAERS, the FDA’s public side-effect reporting system (3,546 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Venoocclusive disease 564 reports
Multiple organ dysfunction syndrome 343 reports
Venoocclusive liver disease 336 reports
Hypotension 159 reports
Hemorrhage 155 reports
