Wintergreen and Amlodipine Besylate

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 Amlodipine Besylate and Wintergreen 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.

Wintergreen safety at a glance

Wintergreen overall Use caution Topical use may be acceptable for adults, but the essential oil is extremely toxic if swallowed.
Pregnancy Avoid Avoid because of the aspirin-like (salicylate) content and lack of safety data.
Breastfeeding Likely Unsafe When used orally or topically. Wintergreen products are likely toxic to nursing infants. Read the full breastfeeding detail

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Amlodipine Besylate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Amlodipine Besylate is filed under 5 classifications — including calcium channel blockers, antihypertensive drugs, cytochrome p450 3a4 (cyp3a4) substrates. Wintergreen has documented interactions with 2 drug classes — the most serious being warfarin (coumadin) (major) and aspirin (moderate) — and none of Amlodipine Besylate’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

What Wintergreen Itself Has Been Linked To

This is not an interaction — nothing below involves Amlodipine Besylate. It is the side-effect record for Wintergreen on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Wintergreen, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Confusion Worth acting on Additional detail

    “Orally, wintergreen oil can result in symptoms of salicylate poisoning, including headache, tinnitus, and confusion.”

  • Ringing in the ears / Headache Additional detail

    Recorded for Wintergreen in the same Natural Medicines adverse-effect record shown under Confusion above.

  • Stomach pain / Diarrhea / Vomiting / Nausea Additional detail

    “Orally, wintergreen oil can result in symptoms of salicylate poisoning, including nausea, vomiting, diarrhea, and stomach pain. Wintergreen causes gastrointestinal irritation (19).”

  • A skin rash Additional detail

    “Wintergreen oil can cause contact dermatitis, which can be irritant or allergic in nature (18,3811,112157). When the oil is applied topically it should not be covered with an occlusive dressing because this could result in absorption of toxic amounts of methyl salicylate.”

Everything above comes from the Natural Medicines adverse-effect record for Wintergreen — expand a row for the licensed statement it rests on. We haven’t matched Amlodipine Besylate to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Amlodipine Besylate.

About Wintergreen

What is Wintergreen?

  • Muscle and joint pain (topical)
  • Arthritis discomfort
  • Headaches
  • Sore throat and oral care
  • Flavoring agent

Wintergreen is a low-growing North American plant whose oil is rich in methyl salicylate, an aspirin-like compound used in topical pain rubs. While it may help ease minor muscle and joint pain when applied to the skin, the concentrated oil is highly toxic if swallowed and should never be taken by mouth. Talk with a pharmacist or doctor before using wintergreen products, especially around children.

Gaultheria procumbens · Ericaceae · Leaves and essential oil · Essential oil, topical creams and ointments, liniments, tea, lozenges, flavoring

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

Wintergreen: dosing

There is no well-established standardized dose for wintergreen. For topical products, follow the directions on the package and apply only a thin layer to the affected area as directed, no more than the label allows.Avoid taking wintergreen oil or large amounts of the herb by mouth.
