Drug & supplement interaction

D-mannose + Adenosine (prescription drug)

Adenosine (prescription drug) brand names: Adenocard, Adenocor, Adenoscan.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 27, 2026
The bottom line No known interaction

We found no known interaction between D-mannose and Adenosine (prescription drug) 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

D-mannose and Adenosine (prescription drug)

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 Adenosine (prescription drug) and D-mannose 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 D-mannose at all — not against Adenosine (prescription drug), 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.

D-mannose safety at a glance

D-mannose overall Use caution Generally well tolerated short-term, but high-quality long-term safety data are limited.
Pregnancy Use caution Not enough reliable safety data, so it is best to avoid unless your doctor advises otherwise.
Breastfeeding Use caution Safety while breastfeeding is not well studied, so caution is advised.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What to actually watch for

No Interaction Found — But Data Suggests D-mannose and Adenosine (prescription drug) 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.

  • Nausea Additional detail

    D-mannose

    “Orally, D-mannose can cause loose stools, diarrhea, abdominal bloating, and nausea. In children, loose stools and abdominal bloating have been reported at D-mannose doses ranging from 100 mg/kg three times daily to 150 mg/kg five times daily. Diarrhea has been reported in adults taking D-mannose 2 grams daily for 6 months.”

    Adenosine (prescription drug)

    Listed in the ADVERSE REACTIONS section of the FDA label for Adenosine (prescription drug). Read the label on DailyMed ›

Reported for D-mannose but not commonly for Adenosine (prescription drug): diarrhea and bloating or gas.

Effects for Adenosine (prescription drug) come from the ADVERSE REACTIONS section of its FDA label; effects for D-mannose come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 1,600 voluntary FDA FAERS reports for Adenosine (prescription drug) 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.

See Every Supplement That Interacts With Adenosine (prescription drug)

This page covers D-mannose only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Adenosine (prescription drug) page lists 12 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Black Tea (moderate), Caffeine (moderate), Cocoa (moderate), Coffee (moderate) and Cola Nut (moderate).

By severity: 12 moderate.

From our pharmacist’s overview on the Adenosine (prescription drug) page

“Adenosine (Adenocard, Adenoscan) is given by IV in the hospital, either to reset a racing heartbeat or to stress the heart for a cardiac imaging test, and every one of the 12 supplement interactions on file traces back to one ingredient: caffeine. Coffee, tea, guarana, and the other caffeine sources on this page can compete with adenos…”

About D-mannose

What is D-mannose?

D-mannose
  • Preventing urinary tract infections (UTIs)
  • Treating mild UTIs
  • Urinary tract health
  • Carbohydrate-deficient glycoprotein syndrome (a rare genetic condition)

D-mannose is a natural sugar most often used to help prevent urinary tract infections, especially those caused by E. coli. Early research is promising for prevention, but the evidence is still limited and it should not replace antibiotics for an active infection. Talk to your pharmacist or doctor before using it, particularly if you are pregnant, breastfeeding, or have diabetes.

Simple sugar (monosaccharide) derived from plants such as cranberries, apples, and other fruits and vegetables · Capsules, tablets, powder; often combined with cranberry

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

D-mannose: dosing

There is no official, standardized dose of D-mannose, and the amounts used in research have varied. Do not use D-mannose in place of prescribed antibiotics for an active infection.

From our D-mannose monograph — the full record covers uses, side effects and every documented interaction.
