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 Perilla and Trimipramine 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

Perilla and Trimipramine

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 Trimipramine and Perilla 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 Perilla at all — not against Trimipramine, 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 Perilla and Trimipramine 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.

    Trimipramine

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

Reported for Perilla but not commonly for Trimipramine: a severe allergic reaction and wheezing.

Effects for Trimipramine come from the ADVERSE REACTIONS section of its FDA label; effects for Perilla come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 1,449 voluntary FDA FAERS reports for Trimipramine 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.

Overlapping uses

What Trimipramine Is Prescribed For, and What Perilla Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Trimipramine is a prescription medicine with approved uses on its FDA label. Perilla is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Trimipramine is prescribed for: Trimipramine capsules are indicated for the relief of symptoms of depression. Endogenous depression — depression that arises from within, rather than from an obvious outside cause — is more likely to respond to treatment than other types. In clinical studies, trimipramine worked as well as imipramine in hospitalized patients with depression, and was comparable to amitriptyline in less severely depressed outpatients.

Perilla has been studied for:

  • Depression studied, not established Perilla has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Perilla for depression

    Although there has been interest in using oral perilla for depression, there is insufficient reliable information about the clinical effects of perilla for this purpose.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Trimipramine on your own; if you are taking Perilla for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Trimipramine

This page covers Perilla only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Trimipramine page lists 139 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), American Hellebore (major), Arsenic (major), Cesium (major) and Ephedra (major).

By severity: 9 major · 100 moderate · 30 minor.

From our pharmacist’s overview on the Trimipramine page

“If you take trimipramine (Surmontil), a tricyclic antidepressant, read this list carefully. Nine of the 139 supplements and herbs on file are rated major, and most touch the heart: several, grapefruit among them, can stretch the QT interval, the heart's electrical reset time, and raise the risk of a dangerous rhythm.”

About Perilla

What is Perilla?

Perilla
  • Seasonal and food allergies
  • Asthma and airway inflammation
  • Atopic dermatitis (eczema)
  • Digestive upset
  • General anti-inflammatory support

Perilla is an Asian mint-family plant used in cooking and traditional medicine, mainly for allergy, breathing, and digestive complaints. Most human evidence is limited or preliminary, so it should not replace proven treatments. It is generally well tolerated as a food, but talk with your pharmacist or doctor before using concentrated supplements.

Perilla frutescens · Lamiaceae · Leaves, seeds, stem, and seed oil · Tea, capsules, seed oil, essential oil, dried leaf, culinary herb

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

Perilla: dosing

There is no well-established standard dose for perilla supplements. Products vary widely in their form and strength, from leaf teas to seed oil softgels to standardized extracts.The safest approach is to follow the directions on the product label and not to exceed them.

Taking Perilla and Trimipramine Together: Common Questions

Is it safe to take Perilla with Trimipramine?
We do not list a known interaction between Perilla and Trimipramine. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Perilla and Trimipramine 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. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Are Perilla and Trimipramine used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Perilla in each. That is a conversation for your prescriber, especially if Trimipramine is being adjusted to a target.
Does Trimipramine interact with any supplements?
Yes. Trimipramine has documented interactions with 139 supplements in our database — Perilla is not one of them. The Trimipramine interaction page linked on this page lists every one, ranked by severity.
