Yellow Dock and Acetazolamide

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

Major

DIURETIC DRUGS

Why this applies to Acetazolamide

Acetazolamide falls under DIURETIC DRUGS — the group Yellow Dock interacts with.

Theoretically, yellow dock might increase the risk of hypokalemia when taken with diuretics.
When yellow dock is used chronically or in large amounts, hypokalemia may occur, and overuse of yellow dock might compound diuretic-induced potassium loss.
Severity Major Likelihood Probable Evidence D

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

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

Here's the concern with pairing yellow dock and acetazolamide. Acetazolamide already nudges your kidneys to dump more potassium in the urine. Yellow dock root contains anthraquinones, the same laxative-type compounds found in senna, and when used heavily or long-term these can also drain potassium from your body. Stack the two and you could lose more potassium than either would cause alone.

Low potassium (hypokalemia) can show up as muscle weakness or cramps, fatigue, or an irregular heartbeat. I'll be straight with you though: this is a theoretical worry based on how each works, not something proven in studies, and an occasional small dose of yellow dock is far less of a concern than daily, large amounts. Please run it by your pharmacist or doctor before combining them.

From our pharmacist’s overview on the Acetazolamide page

“Acetazolamide, taken for glaucoma, altitude sickness, and certain seizure types, works partly as a diuretic and can make people drowsy, and most of the supplements that interact with it press on one of those two points.

About Yellow Dock

What is Yellow Dock?

  • Constipation
  • Digestive support
  • Skin conditions
  • Iron-deficiency or 'blood-building' tonic
  • Liver and detox support

Yellow dock is a traditional herb used mostly as a mild laxative and a digestive and skin tonic. Good-quality human studies are lacking, so its benefits are largely unproven, and its naturally occurring oxalates and anthraquinones mean it should be used cautiously and not long-term.

About Acetazolamide

What Is Acetazolamide Used For?

Brand names: Diamox, Ak-Zol

Acetazolamide is used as an add-on (adjunctive) treatment. Across products, it is used for glaucoma, which is high pressure inside the eye.

Some products have more uses. Acetazolamide tablets and Acetazolamide injection are also used for swelling (edema) from congestive heart failure, drug-induced edema, and certain epilepsies (petit mal and unlocalized seizures). Acute mountain sickness prevention is listed for the tablets, the extended-release capsules, and one of the injection labels, but not every injection product.
