HelloPharmacist Scorecard of Uva Ursi by BIOVEA

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: organic uva ursi, a plant traditionally used for urinary tract support. The liquid also contains grain alcohol and deionized water as inactive ingredients.

Does it work?

Leans against
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Leans against

The strongest graded evidence we hold for the stated purpose leans against a benefit.

Why this rating?
  • The label markets this product for: urinary tract health and comfort.
  • We looked for evidence on: Urinary tract infections (UTIs), urinary discomfort, kidney health, diuretic support.
  • The closest evidence on file: Uva Ursi is rated "Possibly Ineffective" for Urinary tract infections (UTIs) (Natural Medicines).

Uva ursi is possibly ineffective for urinary tract infections (UTIs) based on the evidence we have on file. For bronchitis and benign prostatic hyperplasia (BPH), there isn't enough reliable evidence to rate whether it works.

The data doesn't establish clear effectiveness for the conditions this product is marketed for.

The evidence, ingredient by ingredient Uva Ursi

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Uva ursi is generally well tolerated when taken in low doses for a short time. The most common side effects are diarrhea, nausea, stomach upset, and vomiting.

At very high doses — above 20 grams of dried herb — it can cause serious effects including convulsions, delirium, shortness of breath, and in extremely high doses (30 grams or more), it may be fatal. The product label should tell you the dose; if you're taking it, stick to short-term use and don't exceed what's recommended.

Do not use this product during pregnancy — it may stimulate the uterus and safety data is lacking. There isn't enough information to use it while breastfeeding either.

If you're pregnant, planning to be, or breastfeeding, talk with your pharmacist or doctor before starting.

Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Uva Ursi.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: lithium.
  • For scale: 804 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking Uva Ursi by BIOVEA, double-check these medication types with your pharmacist: drugs metabolized by CYP3A4 and CYP2C19 (moderate risk), glucuronidated drugs (moderate), lithium (moderate), urinary acidifying agents (moderate), and P-glycoprotein substrates (minor). Your pharmacist can tell you which of your medications fall into these groups and whether it's safe to combine them with this product.

The bottom line

Scorecard at a glanceFully disclosed formula with graded evidence leaning against its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Uva ursi may be worth considering if you're looking for short-term urinary tract support, though evidence of effectiveness is limited. Because it interacts with a large number of medications through multiple pathways, you need to check your exact prescriptions — especially if you take lithium or drugs metabolized by your liver.

Talk with your pharmacist before starting, particularly if you're on regular medications.

organic Uva Ursi6 drug types · 803 drugs

Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, uva ursi may decrease the metabolism of CYP2C19 substrates.
In vitro, uva ursi appears to inhibit cytochrome CYP2C19. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, uva ursi may decrease the metabolism of CYP3A4 substrates.
In vitro, uva ursi appears to inhibit CYP3A4. This effect has not been reported in humans.

Likelihood Possible Evidence D
Glucuronidated Drugs

Theoretically, uva ursi may increase levels of drugs metabolized by glucuronidation.
In vitro, uva ursi extract appears to strongly inhibit UDP-glucuronosyltransferase (UGT) 1A1 (UGT1A1). However, uva ursi extract does not appear to inhibit UGT1A1 in animal models. This effect has not been reported in humans.

Likelihood Possible Evidence D
Lithium

Theoretically, uva ursi may increase lithium levels, necessitating a decrease in dose.
Uva ursi may have diuretic properties. Diuretics may increase lithium reabsorption with sodium in the proximal tubule of the kidney. Theoretically, uva ursi might reduce excretion and increase levels of lithium.

Likelihood Probable Evidence D
Urinary Acidifying Agents

Effects of uva ursi in the urinary tract may be reduced by urinary acidifying agents.
Uva ursi seems to work best in alkaline urine. Theoretically, taking uva ursi with medications known to acidify the urine may decrease any effects of uva ursi on the urinary tract.

Likelihood Possible Evidence D
P-Glycoprotein Substrates

Theoretically, uva ursi may alter the levels of drugs transported by P-glycoprotein.
In vitro, uva ursi appears to inhibit the multi-drug transporter protein, P-glycoprotein. This effect has not been reported in humans.

Does Uva Ursi by BIOVEA interact with any medications?
Yes. Based on its ingredients, Uva Ursi has a known interaction with 803 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Uva Ursi contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
How do I know if my medication is affected?
Use the medication checker on this page with your prescription names. If you take lithium, that's a particular concern — uva ursi may raise its level. If you're unsure, ask your pharmacist to review your medications against uva ursi's interactions.
What are the side effects?
At normal doses, most people experience no problems. Nausea, diarrhea, stomach upset, and vomiting are the most common side effects when they occur. At very high doses (above 20 grams), serious effects like convulsions and delirium have been reported.
How long can I safely take this?
Uva ursi is intended for short-term use only. It can be toxic at high doses or with prolonged use, so don't treat it as a daily supplement. Follow the dose on the label and don't exceed it.
Can I use this while pregnant or breastfeeding?
No — avoid uva ursi during pregnancy because it may stimulate the uterus and safety data is missing. There also isn't enough information to use it while breastfeeding. Talk with your doctor or pharmacist if you have questions about alternatives.
Does uva ursi actually work for urinary tract infections?
The evidence suggests it's possibly ineffective for UTIs based on what we have on file. For other uses like bronchitis or prostate health, there isn't enough reliable evidence to say whether it works.
