Agrimony and Phenelzine Sulfate

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 Phenelzine Sulfate and Agrimony 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.

How we checked

Why No Interaction Is Listed for Phenelzine Sulfate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Phenelzine Sulfate is filed under 6 classifications — including monoamine oxidase inhibitors (maois), antidepressant drugs, serotonergic drugs. Agrimony has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Phenelzine Sulfate’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 Phenelzine Sulfate’s Own FDA Label Lists

This is not an interaction — none of it involves Agrimony. These are the most notable effects listed in the ADVERSE REACTIONS section of Phenelzine Sulfate’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. 9 of them are worth acting on rather than waiting out — marked below.

  • Low mood Worth acting on mentioned in 11.9% of FDA reports for Phenelzine Sulfate
  • Dependence or withdrawal symptoms Worth acting on
  • Trouble passing urine Worth acting on
  • Unsteadiness Worth acting on
  • Hallucinations Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • Confusion Worth acting on
  • Seizures Worth acting on
  • A low white blood cell count Worth acting on
  • Weight gain mentioned in 7.8% of FDA reports for Phenelzine Sulfate

Showing the 10 most notable of 31 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Phenelzine Sulfate. Read the label on DailyMed › Where a percentage is shown, it is the share of 1,559 voluntary FDA FAERS reports for Phenelzine Sulfate that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Agrimony’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Agrimony side to compare — that is a limit of the record, not a statement that Agrimony has no side effects.

About Agrimony

What is Agrimony?

Agrimony
  • Sore throat and mouth irritation
  • Mild diarrhea and digestive upset
  • Minor wounds and skin irritation
  • Gallbladder and liver complaints
  • Blood sugar support

Agrimony is a traditional European herb rich in tannins that has long been used for sore throats, mild diarrhea, and minor skin problems. Good-quality human studies are very limited, so its benefits remain unproven. If you choose to try it, use it short-term, follow the product label, and check with your pharmacist or doctor first.

Agrimonia eupatoria · Rosaceae · Dried above-ground parts (leaves, stems, flowers) and seeds · Tea, tincture, liquid extract, capsules, gargle or mouth rinse, topical preparations

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

Agrimony: dosing

There is no well-established, standardized dose for agrimony. Traditional use has been mainly as a tea made from the dried herb, or as a tincture or liquid extract.If you choose to use an agrimony product, follow the directions on the label and do not exceed the recommended amount.

About Phenelzine

What Is Phenelzine Used For?

Brand name: Nardil

Phenelzine is used to treat depression — specifically the types described as atypical, nonendogenous, or neurotic depression. This often includes people who have a mix of anxiety and depression, or who have phobic or hypochondriacal features (strong fears about illness or physical symptoms).

It is generally not the first antidepressant a doctor will try. It is best suited for patients who have already tried other antidepressants without enough relief. There is less evidence supporting its use in severe depression with classic biological features (called endogenous depression).

Most-Reported Side Effects for Phenelzine Sulfate

From FAERS, the FDA’s public side-effect reporting system (1,563 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Depression 187 reports
Headache 138 reports
Anxiety 129 reports
Weight increased 122 reports
Insomnia 104 reports
