Alchemilla and Doxepin

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

Minor

Topical Drugs

Why this applies to Doxepin

Doxepin 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.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the key thing about this one: it only applies to the skin form of doxepin (like Zonalon cream), not the pills or liquid you swallow for sleep, depression, or anxiety. If you're taking doxepin by mouth, Alchemilla isn't expected to cause any problem at all.

The concern is simply local irritation. Alchemilla is high in tannins, which dry and tighten the skin, and doxepin cream can already cause stinging, burning, or itching where you apply it. Putting both on the same patch of skin could add up to more redness or discomfort. This is a minor, theoretical concern based on weak evidence, so don't be alarmed. If you do use both topically, keep an eye on the area and check with your pharmacist if it gets irritated.

From our pharmacist’s overview on the Doxepin page

“Doxepin is a sedating tricyclic prescribed for depression, anxiety, and often sleep itself, and the people taking it tend to shop the same shelf where the trouble sits. Of the 186 supplements on file, 78 deepen its drowsiness, with alcohol (beer and wine carry major, well-documented ratings) and kava the clearest examples, and I would…”

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.
