Alchemilla and Mupirocin

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

Minor

Topical Drugs

Why this applies to Mupirocin

Mupirocin 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 good news first: this isn't a deep, body-wide interaction. Mupirocin (Bactroban) is an antibiotic ointment that works right where you put it on the skin, and Alchemilla is being used here on the skin too. Neither one is affecting how the other is broken down inside your body, so we're really just talking about both products sitting on the same patch of skin.

The concern is simple: Alchemilla is loaded with tannins, which are drying and a little irritating, and one small mouth study showed some folks got local irritation from it. Put on top of an area you're already treating with mupirocin, that could mean more redness, stinging, or itching where you applied it. The evidence is weak and theoretical, so don't panic. Still, if you're treating impetigo or another skin infection, it's smart to run the combo past your pharmacist or doctor first.

From our pharmacist’s overview on the Mupirocin page

“Rubbing DMSO onto skin that is also being treated with mupirocin (Bactroban), a prescription antibiotic ointment for skin infections such as impetigo, could push more of the drug through the skin than intended, raising both its effects and its side effects. That is the biggest concern on a short list.”

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.
