Drug & supplement interaction

Trailing Arbutus + Dalteparin

Dalteparin brand name: Fragmin.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Trailing Arbutus and Dalteparin 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.

Trailing Arbutus and Dalteparin

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 Dalteparin and Trailing Arbutus 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 Trailing Arbutus at all — not against Dalteparin, 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.

No Interaction Found — But Data Suggests Trailing Arbutus and Dalteparin May Share a Side Effect

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.

  • Bleeding or bruising Worth acting on Additional detail

From our pharmacist’s overview on the Dalteparin page

“Dalteparin (Fragmin) is an injectable blood thinner used to prevent and treat dangerous clots, which is exactly why this list warrants real vigilance, and nearly all 218 ingredients on it thin the blood too. They are herbs and extracts with clot-inhibiting or antiplatelet effects of their own, so stacking them on dalteparin can push bl…”

About Trailing Arbutus

What is Trailing Arbutus?

  • Urinary tract complaints
  • Bladder irritation
  • Kidney support (traditional)
  • Mild diuretic

Trailing Arbutus is a low-growing North American woodland plant traditionally used in folk medicine for urinary and bladder complaints. There is very little modern scientific research on its safety or effectiveness, so it cannot be recommended with confidence. Talk to your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Epigaea repens · Ericaceae · Leaves (occasionally the whole flowering plant) · Tea, tincture, dried herb

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

Trailing Arbutus: dosing

There is no established or standardized dose for Trailing Arbutus. It has not been studied enough to know a safe and effective amount, and quality of commercial products is not guaranteed.If you choose to use a product that contains it, follow the directions on the label and do not exceed them.

About Dalteparin Injection

What Is Dalteparin Injection Used For?

Brand name: Fragmin

Fragmin (dalteparin) injection is used to prevent blood clots (deep vein thrombosis and pulmonary embolism) in patients having abdominal surgery, hip replacement surgery, or in medical patients who are severely immobile during a serious illness. It is also used to reduce the risk of dangerous complications from unstable angina and a type of heart attack called non-Q-wave myocardial infarction, given alongside aspirin.

Fragmin is also used for the extended treatment of symptomatic venous thromboembolism (VTE — blood clots in the veins or lungs) to prevent recurrence in adult cancer patients, and for the treatment of symptomatic VTE in children from birth (gestational age at least 35 weeks). Fragmin is not intended for the immediate (acute) treatment of VTE.
