Drug & supplement interaction

Cannabidivarin (cbdv) + Defibrotide Sodium

Defibrotide Sodium brand name: Defitelio.

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 Cannabidivarin (cbdv) and Defibrotide Sodium 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.

Cannabidivarin (cbdv) 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 Cannabidivarin (cbdv) 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 Cannabidivarin (cbdv) 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 to actually watch for

No Interaction Found — But Data Suggests Cannabidivarin (cbdv) and Defibrotide Sodium 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. One of them is worth acting on rather than waiting out — marked below.

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 Cannabidivarin (cbdv)

What is Cannabidivarin (cbdv)?

  • Epilepsy and seizures
  • Autism spectrum disorder
  • Rett syndrome
  • Fragile X syndrome
  • Nausea
  • Anxiety

Cannabidivarin (CBDV) is a non-intoxicating compound found in cannabis that is being studied mainly for epilepsy and certain neurodevelopmental conditions. The research is still early, mostly from laboratory and animal studies plus small human trials, so it is not an approved or proven treatment. Talk to your pharmacist or doctor before trying any CBDV product.

Cannabaceae · Compound derived from the flowers and leaves of the cannabis plant · Oils, tinctures, isolates, and research-grade formulations

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

Cannabidivarin (cbdv): dosing

There is no established standard dose for CBDV. The amounts used in research studies were chosen for those specific trials and are not the same as general supplement guidance.If you choose to use a CBDV product, follow the directions on the product label and start low.

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
