Red Maple and Dronabinol

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 Dronabinol and Red Maple 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 Red Maple at all — not against Dronabinol, 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 Dronabinol’s Own FDA Label Lists

This is not an interaction — none of it involves Red Maple. These are the most notable effects listed in the ADVERSE REACTIONS section of Dronabinol’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. 8 of them are worth acting on rather than waiting out — marked below.

  • Memory problems Worth acting on
  • Unsteadiness Worth acting on
  • Hallucinations Worth acting on
  • Fainting Worth acting on
  • Confusion Worth acting on
  • Seizures Worth acting on
  • Hives Worth acting on
  • An allergic reaction Worth acting on
  • Vivid dreams or nightmares
  • Weight loss

Showing the 10 most notable of 31 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 Dronabinol. Read the label on DailyMed › Where a percentage is shown, it is the share of 7,993 voluntary FDA FAERS reports for Dronabinol that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Red Maple’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Red Maple side to compare — that is a limit of the record, not a statement that Red Maple has no side effects.

From our pharmacist’s overview on the Dronabinol page

“A glass of grapefruit juice can push dronabinol (Marinol, Syndros), the prescription form of THC used for chemotherapy nausea and appetite loss, to higher blood levels than intended, amplifying dizziness, sedation, and its mind-altering effects. That is one of three major-rated interactions among the 151 supplements and herbs on file,…”

About Red Maple

What is Red Maple?

  • Eye and skin irritation (traditional washes)
  • Coughs and sore throat
  • Digestive complaints
  • General tonic
  • Source of edible sap and syrup

Red maple is a common North American tree best known as a source of maple sap, with a long history of traditional Native American medicinal use of its bark and leaves. There is very little modern human research to support any health benefit, so it should not be relied on to treat any condition. Importantly, red maple leaves are highly toxic to horses, and people should use caution and talk to a healthcare provider before using any red maple product.

Acer rubrum · Sapindaceae · Bark, leaves, and sap · Tea, bark decoction, tinctures, and sap/syrup (food use)

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

Red Maple: dosing

There is no established or standardized medicinal dose for red maple. Traditional preparations were made as teas or decoctions of the bark or leaves, but amounts varied widely and were not measured in a consistent way.If you choose to use a commercial product, follow the directions on the label and do not exceed them.

About Dronabinol

What Is Dronabinol Used For?

Brand names: Marinol, Syndros

Dronabinol — available as capsules (Marinol, Dronabinol) and as an oral solution (Syndros, Dronabinol oral solution) — is approved for two conditions in adults. First, it treats anorexia (severely reduced appetite) associated with weight loss in patients with AIDS. Second, it controls nausea and vomiting caused by cancer chemotherapy in patients who have not gotten enough relief from standard anti-nausea treatments.

Both uses apply to all available formulations, but dosing timing and meal instructions differ between the capsule and oral solution products. Always follow the specific instructions for the product you have been prescribed.

Most-Reported Side Effects for Dronabinol

From FAERS, the FDA’s public side-effect reporting system (7,993 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Nausea 894 reports
Fatigue 708 reports
Diarrhea 615 reports
Vomiting 591 reports
Decreased appetite 452 reports
