Alchemilla and Clascoterone

Here is the interaction we found between these two, with the evidence behind it.

Minor

Topical Drugs

Why this applies to Clascoterone

Clascoterone falls under Topical Drugs — the group Alchemilla interacts with.

While no side effects have been reported from orally using Alchemilla, a clinical study titled "Treatment of Aphthous Stomatitis with Topical Alchemilla vulgaris in Glycerine," published in Clinical Drug Investigation (https://pubmed.ncbi.nlm.nih.gov/17163290/), found that local mouth irritation occurred after applying a commercial product containing 3% alchemilla extract and glycerol (Aphtarine, Laboratoires Biosphere). Aphtarine was non-irritating in 68.2% of cases within 2-3 days, in 18.8% of cases within 4-7 days, and in 13.6% of cases with moderate irritation. Theoretically, combining Alchemilla with other potentially irritating topical products could increase the risk of local irritation and discomfort. The drug in this drug interaction monograph is available in a topical dosage form. There is no interaction expected from the oral dosage form of the drug.
Severity Minor Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Here's the practical picture with Winlevi (clascoterone), the topical cream used for acne. This isn't a drug that gets absorbed and broken down in a way Alchemilla would change. The concern here is much simpler: it's all about your skin's surface. Alchemilla is loaded with tannins, which are astringent and can dry and irritate skin in some people. Clascoterone itself can cause dryness, redness, peeling, or a stinging feeling where you apply it.

So if you put a topical Alchemilla product on the same areas, you could just add up the irritation and end up with more redness or burning than either would cause alone. This is a minor, theoretical concern based on weak evidence, not a dangerous reaction. If you'd like to use both, space them out or run it by your pharmacist or dermatologist first.

About Alchemilla

What is Alchemilla?

Alchemilla
  • Menstrual and women's health complaints
  • Diarrhea and digestive upset
  • Wound healing (topical)
  • Skin moisturizing (topical)
  • Mild inflammation

Alchemilla (lady's mantle) is a European herb traditionally used for digestive complaints, women's health issues, and as an astringent for skin and wounds. Solid human research is very limited, so its benefits remain largely unproven, and it should be avoided in pregnancy and breastfeeding due to a lack of safety data.
