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.
What’s inside
Full disclosure
This product contains one active ingredient: uva ursi leaf, 460 mg per capsule. Uva ursi is a plant traditionally used for urinary tract support.
The capsule itself is made from vegetable cellulose, and the formula includes rice bran extract as an inactive ingredient.
Does it work?
Leans against
The evidence for uva ursi is limited. For urinary tract infections, it's rated possibly ineffective — meaning it's not likely to help.
For bronchitis and benign prostatic hyperplasia (enlarged prostate), there isn't enough reliable evidence to know either way.
How safe is it?
Well-documented data
Uva ursi is generally well tolerated at low doses, short-term. The most common side effects are diarrhea, nausea, stomach upset, and vomiting.
The safety data advises against using it during pregnancy because it may stimulate the uterus and hasn't been studied enough. There isn't enough information to know whether it's safe while breastfeeding, so avoid it then too.
Don't use it long-term or at high doses — at very high doses (30 grams or more), uva ursi can be toxic and potentially fatal.
Meds to double-check
Moderate interaction found
Before starting this product, check with your pharmacist if you take anything metabolized by CYP3A4 or CYP2C19 enzymes, lithium, glucuronidated drugs (including acetaminophen and many others), urinary acidifying agents, or drugs transported by P-glycoprotein — all have Moderate interactions except the last, which is Minor.
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 is a short-term supplement for urinary tract issues, though the evidence it works is weak. If you take any medications metabolized by your liver, use lithium, or take urinary acidifying agents, check with your pharmacist first.
Pregnant or breastfeeding? Skip it.
Keep doses low and use it only briefly.
Educational only — not medical advice; always confirm with your pharmacist. Our editorial policy · How we use AI

Uva Ursi 460 mg by Solaray Drug Interactions
HelloPharmacist Interaction Report
Solaray's Uva Ursi 460 mg can interact with several medication types.
The main concern is with drugs broken down by your liver's CYP3A4 and CYP2C19 enzymes (Moderate severity) — uva ursi may slow their breakdown and raise their levels in your bloodstream. Lab tests suggest this happens, but it hasn't been confirmed in people yet.
Read the full breakdown — every affected drug type, severity by severity
You'll also want to flag lithium (a mood stabilizer) and glucuronidated drugs — medications your liver processes through a different pathway. Uva ursi may increase lithium levels and could affect how your body clears glucuronidated drugs, both Moderate concerns.
If you take urinary acidifying agents (certain antibiotics and supplements that make your urine more acidic), they may reduce uva ursi's effectiveness in your urinary tract. Minor concern: uva ursi may alter levels of drugs transported by a protein called P-glycoprotein.
Altogether, these interactions span 790 individual medications. Use the medication checker on this page to look up your exact prescriptions before you start.

For each ingredient in Uva Ursi 460 mg with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Uva Ursi
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.
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.
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.
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.
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.
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.
