No Known Interaction
The bottom line No known interaction

We found no known interaction between Chervil and Isocarboxazid 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.

Chervil and Isocarboxazid

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 Isocarboxazid and Chervil 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 Chervil at all — not against Isocarboxazid, 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

What Isocarboxazid’s Own FDA Label Lists

This is not an interaction — none of it involves Chervil. These are the most notable effects listed in the ADVERSE REACTIONS section of Isocarboxazid’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both.

  • Dry mouth
  • Dizziness
  • Nausea

From the ADVERSE REACTIONS section of the FDA label for Isocarboxazid. Read the label on DailyMed › Chervil’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Chervil side to compare — that is a limit of the record, not a statement that Chervil has no side effects.

The most serious there right now: Activated Charcoal (major), Beer (major), Bitter Orange (major), Brewer's Yeast (major) and Cowhage (major).

From our pharmacist’s overview on the Isocarboxazid page

“Isocarboxazid (Marplan) is an MAOI antidepressant, and that drug class carries some of the sharpest supplement and food hazards in the pharmacy, so read this list closely rather than skimming it. Fourteen of the 81 entries rate major, and most of the danger runs through tyramine.”

About Chervil

What is Chervil?

  • Digestive upset
  • Mild fluid retention (diuretic)
  • Skin and eye compresses (traditional)
  • Culinary seasoning
  • General 'spring tonic' or cleansing

Chervil is a delicate culinary herb in the carrot and parsley family that has long been used in folk medicine for digestion and as a mild diuretic. There is very little modern scientific research to confirm any health benefit, so it is best thought of as a flavorful food rather than a proven remedy. It is generally regarded as safe in food amounts, but concentrated supplements and the essential oil are not well studied.

Anthriscus cerefolium · Apiaceae · Leaves (fresh or dried) and aerial parts · Fresh or dried herb, tea (infusion), juice, and occasionally essential oil

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

Chervil: dosing

There is no established standardized medicinal dose for chervil. It is most commonly used in cooking, where the amount is small and considered safe.If you choose to use a chervil tea or supplement product, follow the directions on the label and do not exceed the recommended amount.

About Isocarboxazid

What Is Isocarboxazid Used For?

Brand name: Marplan

Marplan (isocarboxazid) is indicated for the treatment of depression — specifically, major depressive disorder. Because it carries serious risks, it is not a first-choice antidepressant. Marplan is generally reserved for patients who have not responded adequately to other antidepressants.

Clinical trials showed Marplan to be effective in adult outpatients with major depressive disorder, including those whose depression was accompanied by anxiety symptoms such as panic or phobias. Marplan is not approved for use in children or adolescents.
