The short answer
It is not established that bearberry adds to torsemide-related low blood pressure. The main practical issue is reviewing the exact leaf product and kidney history, without assuming traditional urinary use proves an interaction.
What this answer covers
Arctostaphylos uva-ursi species entry; regulatory evidence concerns specified oral leaf preparations.
- Supplement or preparation
- Arctostaphylos uva-ursi
- Medication ingredient
- torsemide
What is known about the combination
The bearberry leaf monograph reports no interactions, and the reviewed sources do not demonstrate extra hypotension with torsemide. A lack of reports is not proof that every preparation is safe.
Why kidney history matters
The monograph contraindicates these leaf products in women with kidney disorders. Torsemide can worsen kidney function if too much fluid is lost. These separate precautions support a product review but do not establish additive blood-pressure lowering.
The plant part matters
The monograph concerns leaf preparations for short-term lower urinary symptoms. It does not evaluate all extracts, other plant parts or multi-herb blends. The actual ingredients and preparation should be checked rather than relying on the word bearberry.
Respond to symptoms
Tell the treating team about new urinary or weight-loss products, dizziness, faintness, marked thirst or reduced fluid intake. Torsemide can itself cause excess fluid loss and kidney problems. Follow your existing fluid plan rather than increasing fluids or changing torsemide on your own.
Evidence and practical considerations
Side effects & toxicity
No qualifying exact-pair evidence establishes added hypotension; leaf-specific kidney contraindication is a separate concern.
- Exact scope
- Arctostaphylos uva-ursi species entry; regulatory evidence concerns specified oral leaf preparations. with Oral torsemide, exact RxCUI38413 IN; not all loop diuretics or parenteral exposure.
- Medication form and route
- oral torsemide; oral supplement
What remains uncertain
- Source-specific identity and endpoint limits apply; no unstudied dosing recommendation.
Factors that may matter: Dose and duration; Kidney function; Exact preparation; Other medicines.

Population: People prescribed oral torsemide for edema or hypertension.
Excess diuresis may cause dehydration, hypotension and worsening renal function. Electrolyte abnormalities include hypokalemia; monitor serum electrolytes. Low-dose hypertension studies showed small average potassium decreases, with no universal deficiency. Photosensitivity appears among postmarketing reports.
How this applies: Interpret only for the stated species, preparation, route and endpoints; exact torsemide pair evidence is distinguished.
No named botanical interaction for this batch. Postmarketing reports cannot establish frequency or causality. Potassium replacement is not required for every patient.

Population: People using the specified oral preparation.
No interactions reported. The covered leaf products are contraindicated in women with kidney disorders.
How this applies: Interpret only for the stated species, preparation, route and endpoints; exact torsemide pair evidence is distinguished.
Not a torsemide combination or human blood-pressure study; species-level identity does not identify every preparation.
