Drug & supplement interaction

Japanese Mint + Treprostinil (IV)

Treprostinil (IV) brand name: Remodulin.

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 Japanese Mint and Treprostinil (IV) 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

Japanese Mint and Treprostinil (IV)

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 Treprostinil (IV) and Japanese Mint 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 Japanese Mint at all — not against Treprostinil (IV), 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 Japanese Mint and Treprostinil (IV) 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.

From our pharmacist’s overview on the Treprostinil (IV) page

“Bleeding risk is the thread running through nearly every supplement flagged for treprostinil (Remodulin), the IV therapy for pulmonary arterial hypertension. The drug itself discourages platelets from clumping, so the overwhelming majority of these ingredients could push that tendency further, and I would not add anything from this pag…”

About Japanese Mint

What is Japanese Mint?

  • Digestive upset
  • Headache relief (topical)
  • Cold and congestion
  • Muscle and joint aches
  • Itchy skin and minor pain

Japanese mint is a menthol-rich plant used mainly for its essential oil in topical rubs, inhalants, and digestive remedies. There is some support for menthol's soothing and cooling effects, but high-quality studies on Japanese mint itself are limited, and the concentrated oil can be irritating or harmful if misused. Talk to your pharmacist or doctor before using it, especially in children or if pregnant.

Mentha arvensis · Lamiaceae · Leaves and essential oil · Essential oil, topical balms and rubs, tea, capsules, inhalants, lozenges

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

Japanese Mint: dosing

There is no official standardized dose for Japanese mint. The right amount depends heavily on the form — tea, capsule, balm, or essential oil — and on the menthol concentration.The safest approach is to follow the directions on the specific product label and not exceed them. Essential oils should be diluted as directed and are not meant to be swallowed unless a product is specifically made for that use.

About Treprostinil Injection

What Is Treprostinil Injection Used For?

Brand name: Remodulin

Treprostinil injection is used to treat pulmonary arterial hypertension (PAH, WHO Group 1) — high blood pressure in the arteries that supply the lungs. It works to reduce the symptoms that make exercise difficult. Clinical studies included patients with moderate-to-severe PAH symptoms (NYHA Class II–IV) due to idiopathic or heritable PAH, PAH related to congenital heart defects, and PAH related to connective tissue diseases.

It is also used for PAH patients who need to transition off epoprostenol — a related medication — to slow the worsening of their condition during that switch. The risks and benefits of the transition should be carefully discussed with a specialist before starting.
