Alchemilla and Brinzolamide

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

Minor

Topical Drugs

Why this applies to Brinzolamide

Brinzolamide 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

Good news here: this isn't about how your body breaks down brinzolamide. Brinzolamide (Azopt) is eye drops that lower the pressure inside your eye, and it works right there on the surface. Alchemilla won't change how the medicine itself functions.

The only real concern is local irritation. Alchemilla is high in tannins, which are astringent and can be a bit harsh on tender tissues. If you ever put an Alchemilla-containing product near or around your eyes, on top of the mild stinging or blurred vision brinzolamide can already cause, you might notice a little more burning or redness. Taking Alchemilla by mouth shouldn't affect your eye drops at all. If you do use topical Alchemilla close to your eyes, check with your pharmacist or doctor first.

From our pharmacist’s overview on the Brinzolamide page

“Brinzolamide (Azopt) eye drops lower pressure inside the eye in glaucoma, and its supplement record is short enough to learn in a minute. Just three ingredients interact, two rated moderate and one minor, none major, so treat this as a heads-up rather than a warning.”

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.

About Brinzolamide Ophthalmic

What Is Brinzolamide Ophthalmic Used For?

Brand name: Azopt

Brinzolamide ophthalmic suspension 1% is used to treat elevated intraocular pressure (IOP) — that is, higher-than-normal pressure inside the eye. It is prescribed for two conditions: ocular hypertension (high eye pressure without vision loss) and open-angle glaucoma (the most common form of glaucoma).

Keeping eye pressure in a healthy range is important because high IOP is a major risk factor for damaging the optic nerve and losing vision over time.
