Houseleek 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 Houseleek 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 Houseleek at all — not against Phenelzine Sulfate, 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.

Houseleek safety at a glance

Houseleek overall Use caution It has a long history of topical folk use, but modern safety data is limited, especially for taking it by mouth.
Pregnancy Avoid There is not enough reliable safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid Safety while breastfeeding is unknown, so avoiding it is the safer choice.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What Phenelzine Sulfate’s Own FDA Label Lists

This is not an interaction — none of it involves Houseleek. 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. Houseleek’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Houseleek side to compare — that is a limit of the record, not a statement that Houseleek has no side effects.

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Houseleek is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Houseleek reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Houseleek and Phenelzine Sulfate records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Houseleek

What is Houseleek?

  • Minor burns and skin irritation
  • Insect bites and stings
  • Warts and corns
  • Earache (traditional folk use)
  • Soothing cuts and scrapes

Houseleek is a hardy succulent traditionally applied to the skin for minor burns, bites, and irritations, much like aloe vera. Scientific evidence supporting its benefits is very limited and mostly comes from traditional use and laboratory studies, so it should not replace proven treatments. Talk to a pharmacist or doctor before using it, especially during pregnancy or breastfeeding.

Sempervivum tectorum · Crassulaceae · Leaves and the juice (sap) pressed from the leaves · Fresh leaf juice or pulp, poultices, ointments, and occasionally infusions

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

Houseleek: dosing

There is no standardized or well-established dose for houseleek. Traditional use involved applying the fresh leaf juice or crushed leaf pulp directly to the skin as needed, but no proven, measured dosing exists.If you choose to use a commercial product such as an ointment or gel, follow the directions on the label.

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
