The bottom line No known interaction

We found no known interaction between Desert Parsley and Tranylcypromine in our sources.

Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Desert Parsley and Tranylcypromine

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 Tranylcypromine and Desert Parsley 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 Desert Parsley at all — not against Tranylcypromine, 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 Tranylcypromine’s Own FDA Label Lists

This is not an interaction — none of it involves Desert Parsley. These are the most notable effects listed in the ADVERSE REACTIONS section of Tranylcypromine’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. 10 of them are worth acting on rather than waiting out — marked below.

  • Mania or an unusually elevated mood Worth acting on
  • Low mood Worth acting on mentioned in 10.7% of FDA reports for Tranylcypromine
  • Serotonin syndrome Worth acting on
  • Thoughts of self-harm Worth acting on
  • Memory problems Worth acting on
  • Trouble passing urine Worth acting on
  • Unsteadiness Worth acting on
  • Low blood sugar Worth acting on
  • Raised blood pressure Worth acting on mentioned in 7.3% of FDA reports for Tranylcypromine
  • Fainting Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Tranylcypromine. Read the label on DailyMed › Where a percentage is shown, it is the share of 1,111 voluntary FDA FAERS reports for Tranylcypromine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Desert Parsley’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Desert Parsley side to compare — that is a limit of the record, not a statement that Desert Parsley has no side effects.

From our pharmacist’s overview on the Tranylcypromine page

“Tranylcypromine (Parnate) belongs to the MAOI class of antidepressants, and I read its supplement list with real seriousness, since the highest-rated entries can turn dangerous quickly. The drug blocks the enzyme that normally clears tyramine, so tyramine-rich items like brewer's yeast, fermented soy, and even beer or wine can push blo…”

About Desert Parsley

What is Desert Parsley?

  • Respiratory infections and colds
  • Cough and congestion
  • Flu-like illness
  • Immune support
  • Sore throat

Desert Parsley (Lomatium dissectum) is a root used in Native American and Western herbal traditions, mainly for colds, coughs, and respiratory infections. Modern scientific evidence in humans is very limited, and it can cause a widespread skin rash in some people, so use it cautiously and talk with your pharmacist or doctor first.

Lomatium dissectum · Apiaceae · Root · Tincture, capsules, dried root, tea, glycerite extract

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

Desert Parsley: dosing

There is no established standard dose for Desert Parsley. Traditional use varies widely depending on the form, whether it is a tincture, capsule, or tea.Because a safe and effective dose has not been defined in research, follow the directions on the product label and do not exceed them.

About Tranylcypromine

What Is Tranylcypromine Used For?

Brand name: Parnate

Tranylcypromine tablets — sold as Parnate, Tranylcypromine, and Tranylcypromine Sulfate — are used to treat major depressive disorder (MDD) in adults. It is not a first-choice antidepressant; it is specifically for people who have already tried other antidepressants and have not gotten adequate relief.

Because of its serious potential side effects, strict dietary requirements, and many drug interactions, tranylcypromine is reserved for cases where other treatments have not worked. It is not approved for use in children.
