Drug & supplement interaction

Canadian Hemp + Carboplatin

Carboplatin brand name: Paraplatin.

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 Canadian Hemp and Carboplatin 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.

Interaction report

Canadian Hemp and Carboplatin

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 Carboplatin and Canadian Hemp 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 Carboplatin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Carboplatin is filed under 5 classifications — including platinum agents, alkylating agents, antineoplastics. Canadian Hemp has documented interactions with 2 drug classes — the most serious being digoxin (lanoxin) (moderate) and diuretic drugs (moderate) — and none of Carboplatin’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

No Interaction Found — But Data Suggests Canadian Hemp and Carboplatin 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.

  • Raised blood pressure Worth acting on Additional detail

    Canadian Hemp

    “Orally, Canadian hemp can cause digitalis-like toxicity due to its cardiac glycoside constituents. Symptoms of toxicity can include bradycardia with hypotension, increased heart contractions, and reflex hypertension. Canadian hemp can also cause topical irritation of the gastrointestinal mucous membranes.”

Reported for Canadian Hemp but not commonly for Carboplatin: a slow heartbeat.

Effects for Carboplatin come from the ADVERSE REACTIONS section of its FDA label; effects for Canadian Hemp come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 126,273 voluntary FDA FAERS reports for Carboplatin that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Everything else you take

See Every Supplement That Interacts With Carboplatin

This page covers Canadian Hemp only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Carboplatin page lists 27 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Acerola (moderate), Alpha-lipoic Acid (moderate), Coenzyme Q10 (moderate) and Coffee Charcoal (moderate).

By severity: 1 major · 15 moderate · 11 minor.

From our pharmacist’s overview on the Carboplatin page

“Activated charcoal is the one major-rated interaction among the 27 supplements on carboplatin's list, and it earns that spot because charcoal can lower exposure to many drugs even when they are given by vein, as carboplatin (Paraplatin) is. This is chemotherapy, so anything that blunts it puts the treatment itself at risk, and I would…”

About Canadian Hemp

What is Canadian Hemp?

  • Heart-related swelling (dropsy/edema)
  • Fluid retention
  • Constipation
  • Urinary problems
  • Traditional folk remedy uses

Canadian Hemp (Apocynum cannabinum) is a toxic North American plant historically used as a heart stimulant and diuretic, but it contains potent cardiac glycosides that can cause dangerous heart and poisoning effects. It is not a safe or recommended dietary supplement, and there is no reliable modern evidence supporting its use. Avoid using it and talk to a pharmacist or doctor about safer, proven options.

Apocynum cannabinum · Apocynaceae · Dried roots and rhizomes · Tincture, dried root, traditional decoction (rarely sold as a modern supplement)

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

Canadian Hemp: dosing

There is no established safe dose for Canadian Hemp, and we do not provide one. Because it contains potent and potentially deadly heart-acting compounds with a very narrow safety margin, no general dosing guidance can be given.If you come across a product containing Apocynum cannabinum, do not take it without speaking to a pharmacist or doctor first. In nearly all cases, safer and better-studied options are available.

Taking Canadian Hemp and Carboplatin Together: Common Questions

Is it safe to take Canadian Hemp with Carboplatin?
We do not list a known interaction between Canadian Hemp and Carboplatin. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Canadian Hemp and Carboplatin have any of the same side effects?
Yes — our sources link each of them separately to 4 of the same effects. That is not an interaction: neither changes how your body handles the other.

How was the Canadian Hemp and Carboplatin combination checked?
Interactions in our licensed database are recorded against drug classes. Carboplatin is filed under 5 classifications, and Canadian Hemp has documented interactions with 2 drug classes — none of Carboplatin's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
