The bottom line No known interaction

We found no known interaction between Houseleek and Trametinib 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 label for Trametinib states a food rule worth keeping to.

Houseleek and Trametinib

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 Trametinib 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 Trametinib, 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 Trametinib’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 Trametinib’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.

  • A stroke or mini-stroke Worth acting on
  • Severe muscle breakdown Worth acting on
  • Dehydration Worth acting on
  • Bleeding in the gut Worth acting on
  • Low sodium Worth acting on
  • Low potassium Worth acting on
  • A slow heartbeat Worth acting on
  • Heart failure Worth acting on
  • High blood sugar Worth acting on
  • Fainting Worth acting on

Showing the 10 most notable of 58 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 Trametinib. Read the label on DailyMed › Where a percentage is shown, it is the share of 23,697 voluntary FDA FAERS reports for Trametinib 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.

How to take them

Some Trametinib Products Have a Food Rule — Houseleek Should Not Break It

At least one FDA label for a product containing Trametinib says to take it on an empty stomach. Most supplements — Houseleek included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Trametinib on its own and move Houseleek to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Trametinib products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

MEKINIST Tablets Take MEKINIST tablets on an empty stomach (at least 1 hour before or 2 hours after a meal) [see Clinical Pharmacology (12.3)] .

From the Dosage and Administration section of the FDA label we read for Trametinib — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

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 20, 2026. The Houseleek and Trametinib 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 Trametinib

What Is Trametinib Used For?

Brand name: Mekinist

Mekinist is used to treat cancers that have a BRAF V600E or V600K mutation — a specific genetic change that tells cancer cells to grow out of control. It can be used alone or, more often, paired with another targeted medicine called dabrafenib.

On its own, Mekinist treats certain patients with unresectable (cannot be surgically removed) or metastatic (spread to other parts of the body) melanoma who have not previously received a BRAF inhibitor. In combination with dabrafenib, Mekinist is used for metastatic or surgically treated melanoma, metastatic non-small cell lung cancer (NSCLC), locally advanced or metastatic anaplastic thyroid cancer (ATC), certain other BRAF V600E-positive solid tumors in adults and children 1 year and older, and low-grade glioma (a type of brain tumor) in children 1 year and older. A BRAF mutation must be confirmed by an FDA-approved test before starting treatment.

Most-Reported Side Effects for Trametinib

From FAERS, the FDA’s public side-effect reporting system (24,023 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fever 4,068 reports
Malignant neoplasm progression 2,040 reports
Rash 1,736 reports

Taking Houseleek and Trametinib Together: Common Questions

Is it safe to take Houseleek with Trametinib?
We do not list a known interaction between Houseleek and Trametinib. 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.
Should I take Houseleek and Trametinib at the same time of day?
At least one FDA label for a product containing Trametinib says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Trametinib on its own and move Houseleek to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
Does Trametinib interact with any supplements?
Yes. Trametinib has documented interactions with 17 supplements in our database — Houseleek is not one of them. The Trametinib interaction page linked on this page lists every one, ranked by severity.
