HelloPharmacist Scorecard of Uva Ursi 460 mg by Solaray

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Oct 8, 2026

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.

Each capsule contains 460 mg of uva ursi, the product's only active ingredient. Uva ursi is the herb this product is built around, and its interaction and effectiveness details on this page all come from that one ingredient.

The inactive other ingredients listed are cellulose and rice bran extract.

Does it work?

Couldn't assess
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
Not assessable

This is a single-ingredient Uva Ursi product and its label doesn't state a use — see Uva Ursi's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

Our data rates uva ursi as possibly ineffective for urinary tract infections. For bronchitis and benign prostatic hyperplasia (an enlarged prostate), there is insufficient reliable evidence to rate its effectiveness.

Those ratings mean the evidence isn't established in the data we hold, not that the herb has been proven to fail.

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 in low doses taken short-term. The most common side effects are diarrhea, nausea, stomach upset, and vomiting.

Our safety notes also flag it as potentially toxic in high doses or with prolonged use. At high doses, serious effects such as convulsions, delirium, and shortness of breath have been reported, and very high doses of 30 grams or more may be fatal.

In pregnancy, our data rates uva ursi as likely unsafe, and the safety data advises against it because it may stimulate the uterus. Our pregnancy and lactation entry for breastfeeding is blank, and the safety notes say there isn't enough safety information to know its effects.

Meds to double-check

Moderate interaction found
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: 805 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.

Double-check before taking this product if you use lithium, which carries a Moderate interaction. Drugs cleared by CYP2C19 or CYP3A4, drugs processed by glucuronidation, and urinary acidifying agents are also rated Moderate.

P-glycoprotein substrates carry a Minor interaction. Confirm your specific medications with your own doctor or pharmacist.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Uva ursi may be of interest to someone looking for a short-term herbal option for urinary symptoms, though the evidence for that use is weak. If you take lithium or any drug cleared by the CYP enzymes or glucuronidation, you should be especially careful and review it with your prescriber.

Pregnant people should not use it according to the safety data, and anyone who is breastfeeding should talk it over with their own doctor or pharmacist first.

Uva Ursi6 drug types · 804 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.
