Drug & supplement interaction

Japanese Mint + Ranolazine

Ranolazine brand names: Ranexa, Aspruzyo.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Japanese Mint and Ranolazine 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.

Japanese Mint and Ranolazine

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 Ranolazine 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 Ranolazine, 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 Japanese Mint and Ranolazine 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.

  • Headache Additional detail

    Japanese Mint

    “Topically, use of Japanese mint oil on the face in children can trigger glottal or bronchial spasm, asthma-like attacks, or respiratory failure (18). When inhaled, the vapor from Japanese mint oil can cause flushing, headache, or worsening bronchial asthma spasms (11,18).”

    Ranolazine

    Listed in the ADVERSE REACTIONS section of the FDA label for Ranolazine. Read the label on DailyMed ›

Reported for Japanese Mint but not commonly for Ranolazine: a skin rash, flushing and wheezing.

Effects for Ranolazine come from the ADVERSE REACTIONS section of its FDA label; effects for Japanese Mint come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 10,189 voluntary FDA FAERS reports for Ranolazine 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.

From our pharmacist’s overview on the Ranolazine page

“Ranolazine (Ranexa, Aspruzyo), a medicine for chronic chest pain, depends heavily on one liver enzyme, CYP3A4, and that is where most of its supplement trouble sits. Grapefruit can push ranolazine levels up, St.”

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.

Do Japanese Mint and Ranolazine have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other.
