HelloPharmacist Scorecard of Urgent-Less by Priority One Nutritional Supplements

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

Partial disclosure
Ingredient Transparency · database check
Partial

Most active ingredients list an amount, but at least one is hidden in a blend or missing.

Why this rating?
  • The label discloses an exact amount for 3 of its 5 active ingredients.
  • “Go-Less” is listed as a grouped ingredient — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

Urgent-Less contains five active ingredients. Cinnamon (cassia) is included for its traditional uses, though evidence for most of its claimed benefits is insufficient.

Buchu leaf extract is a traditional diuretic herb. Pumpkin, primarily its seeds, has possibly effective evidence for benign prostate enlargement.

Soy provides protein and isoflavones with possibly effective evidence for blood sugar, cholesterol, bone health, and blood pressure. Rehmannia root extract, used in traditional medicine, has possibly effective evidence for chronic kidney disease but limited human safety data.

The product also contains three inactive ingredients: rice chelate, maltodextrin, and a vegetarian capsule (the capsule shell itself).

Does it work?

Moderate evidence
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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Urinary tract and bladder health support.
  • We looked for evidence on: Benign prostatic hyperplasia (BPH), Overactive bladder, Urinary incontinence, Urinary tract infections (UTIs), Interstitial cystitis, Urinary urgency — and 2 related terms.
  • The strongest evidence on file: Pumpkin is rated "Possibly Effective" for Benign prostatic hyperplasia (BPH) (Natural Medicines).
  • Also on file: Soy is rated "Possibly Ineffective" for Benign prostatic hyperplasia (BPH).
  • Also on file: Pumpkin is rated "Insufficient Reliable Evidence To Rate" for Interstitial cystitis, Urinary tract infections (UTIs), Overactive bladder.

Evidence varies by ingredient and condition. Soy shows possibly effective evidence for lowering blood sugar, cholesterol, blood pressure, and supporting bone health, plus possibly effective evidence for diarrhea.

Pumpkin has possibly effective evidence specifically for benign prostate enlargement. Rehmannia has possibly effective evidence for chronic kidney disease.

Cinnamon's evidence is insufficient to rate it for any of its traditional uses—amenorrhea, angina, colds, diabetes, diarrhea, or cholesterol. Buchu has no effectiveness ratings in our data.

Go-Less's ingredients could not be checked since it is a blend.

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 3 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most of these ingredients are generally well tolerated at typical doses. Soy foods eaten as part of a normal diet are safe for most people, though concentrated isoflavone supplements warrant more caution.

Pumpkin as food is well tolerated; the seed-oil concentrate is generally safe for adults but lacks strong data in pregnancy and breastfeeding. Cinnamon in food amounts is fine, but supplement doses high in coumarin may harm the liver over time, and medicinal amounts should be avoided in pregnancy and breastfeeding.

Buchu's safety data are limited at medicinal doses, the oil may be irritating, and it's traditionally thought to affect the uterus, so avoid it in pregnancy and breastfeeding. Rehmannia has limited human safety data and should be avoided in pregnancy and breastfeeding.

Adverse effects reported include: rash and contact dermatitis with cinnamon; abdominal discomfort, diarrhea, nausea, and vomiting with pumpkin (rarely anaphylaxis); and bloating, constipation, diarrhea, nausea, and allergic reactions with soy. Cinnamon at high doses over extended periods raises theoretical liver concerns.

Each ingredient & the kinds of drugs it affects

For each ingredient in Urgent-Less with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Soy12 drug types · 611 drugs

Monoamine Oxidase Inhibitors (Maois)

Taking soy products containing high amounts of tyramine along with MAOIs can increase the risk of hypertensive crisis.
Fermented soy products such as tofu and soy sauce contain tyramine, a naturally occurring chemical that affects blood pressure regulation. The metabolism of tyramine is decreased by MAOIs. Consuming more than 6 mg of tyramine while taking an MAOI can increase the risk of hypertensive crisis. The amount of tyramine in fermented soy products is usually less than 0.6 mg per serving; however, there can be significant variation depending on the specific product used, storage conditions, and length of storage. Storing one brand of tofu for a week can increase tyramine content from 0.23 mg to 4.8 mg per serving. Advise patients taking MAOIs to avoid fermented soy products that contain high amounts of tyramine.

Likelihood Likely Evidence C
Antidiabetes Drugs

Soy can lower blood glucose and have additive effects with antidiabetes drugs.
Clinical research shows that whole soy diets and soy-based meals reduce fasting glucose levels in diabetic and non-diabetic individuals. Also, individuals following a soy-based meal replacement plan seem to require lower doses of sulfonylureas and metformin to manage blood glucose levels when compared with individuals following a diet plan recommended by the American Diabetes Association.

Likelihood Possible Evidence A
Antihypertensive Drugs

Theoretically soy protein may have additive effects with antihypertensive drugs and increase the risk of hypotension.
Although some contradictory research exists, most clinical evidence suggests that consuming soy protein modestly reduces systolic and diastolic blood pressure in individuals with prehypertension or hypertension.

Likelihood Possible Evidence A
Caffeine

Theoretically, soy might reduce the clearance of caffeine.
Soy contains genistein. Taking genistein 1 gram daily for 14 days seems to inhibit caffeine clearance and metabolism in healthy females. This effect has been attributed to inhibition of the cytochrome P450 1A2 (CYP1A2) enzyme, which is involved in caffeine metabolism. It is unclear if this effect occurs with the lower amounts of genistein found in soy.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, soy might have additive effects when used with diuretic drugs.
Animal research suggests that genistein, a soy isoflavone, increases diuresis within 6 hours of subcutaneous administration in rats. The effects seem to be similar to those of furosemide. This effect has not been reported in humans.

Likelihood Possible Evidence D
Estrogens

Theoretically, soy might competitively inhibit the effects of estrogen replacement therapy.
Soy contains phytoestrogens and has been shown to have estrogenic activity in some patients. Although this has not been demonstrated in humans, theoretically, concomitant use of soy with estrogen replacement therapy might reduce the effects of the estrogen replacement therapy.

Likelihood Possible Evidence D
Levothyroxine (Synthroid, Others)

Soy products might reduce the absorption of levothyroxine in some patients.
Preliminary clinical research and a case report suggest that soy-based formulas inhibit the absorption of levothyroxine in infants with congenital hypothyroidism. A levothyroxine dosage increase may be needed for infants with congenital hypothyroidism while using soy-based formulas, and the dose may need to be reduced when soy-based formulas are no longer administered. However, in postmenopausal adults, clinical research shows that taking a single dose of soy extract containing isoflavones 60 mg along with levothyroxine does not affect the oral bioavailability of levothyroxine.

Likelihood Possible Evidence B
Progesterone

Theoretically, combining soy isoflavones with transdermal progesterone may worsen bone density.
Clinical research suggests that significant bone loss may occur in females with osteoporosis who receive a combination of transdermal progesterone with soy milk containing isoflavones when compared with placebo, soy milk alone, or progesterone alone.

Likelihood Possible Evidence A
Tamoxifen (Nolvadex)

Theoretically, estrogenic soy isoflavones might alter the effects of tamoxifen.
Laboratory research suggests that genistein and daidzen, isoflavones from soy, can antagonize the antitumor effects of tamoxifen under some circumstances; however, soy isoflavones might have different effects when used at different doses. A relatively low in vitro concentration of soy isoflavones such as 1 microM/L seems to interfere with tamoxifen, whereas high in vitro concentrations such as those >10 microM/L might actually enhance tamoxifen effects. People on a high-soy diet have soy isoflavones levels ranging from 0.1-6 microM/L. Until more is known, advise patients taking tamoxifen to avoid therapeutic use of soy products.

Likelihood Possible Evidence B
Warfarin (Coumadin)

Theoretically, soy might interfere with the effects of warfarin.
Soy milk has been reported to decrease the international normalized ratio (INR) in a patient taking warfarin. The mechanism of this interaction is not known. However, animal and in vitro research suggests that soy may also inhibit platelet aggregation. Dosing adjustments for warfarin may be necessary.

Likelihood Possible Evidence D
Antibiotic Drugs

Theoretically, antibiotics may decrease the activity of soy isoflavones.
Intestinal bacteria are responsible in part for converting soy isoflavones into their active forms. Antibiotics may decrease the amount of intestinal bacteria and decrease its ability to convert isoflavones.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Soy might modestly induce CYP2C9 enzymes. However, this effect does not seem to be clinically significant.
In vitro research suggests that an unhydrolyzed soy extract might induce CYP2C9. However, the significance of this interaction is likely minimal. In healthy females taking a specific extract of soy (Genistein Soy Complex, Source Naturals), blood levels of losartan, a CYP2C9 substrate, were not significantly affected.

Likelihood Unlikely Evidence D

Short Buchu leaf extract3 drug types · 481 drugs

Anticoagulant/Antiplatelet Drugs

Buchu may have antiplatelet effects. Theoretically, buchu may enhance the effects of anticoagulant or antiplatelet drugs and increase the risk of bleeding in some patients. Some anticoagulant or antiplatelet drugs include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Buchu contains pulegone, a known hepatotoxin. There is some concern that buchu may adversely affect the liver, especially when the leaf is used in large doses or the oil is ingested. Theoretically, concomitant use with hepatotoxic drugs might increase the risk of liver damage. Some of these drugs include acarbose (Precose, Prandase), amiodarone (Cordarone), atorvastatin (Lipitor), azathioprine (Imuran), carbamazepine (Tegretol), cerivastatin (Baycol), diclofenac (Voltaren), felbamate (Felbatol), fenofibrate (Tricor), fluvastatin (Lescol), gemfibrozil (Lopid), isoniazid, itraconazole, (Sporanox), ketoconazole (Nizoral), leflunomide (Arava), lovastatin (Mevacor), methotrexate (Rheumatrex), nevirapine (Viramune), niacin, nitrofurantoin (Macrodantin), pioglitazone (Actos), pravastatin (Pravachol), pyrazinamide, rifampin (Rifadin), ritonavir (Norvir), rosiglitazone (Avandia), simvastatin (Zocor), tacrine (Cognex), tamoxifen, terbinafine (Lamisil), valproic acid, and zileuton (Zyflo)

Likelihood Possible Evidence D
Lithium

Buchu is thought to have diuretic properties. Theoretically, buchu might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Likelihood Probable Evidence D

Cinnamon2 drug types · 442 drugs

Antidiabetes Drugs

Theoretically, cassia cinnamon may have additive effects with antidiabetes drugs.
Cassia cinnamon may lower blood glucose levels, and have additive effects in patients treated with antidiabetic agents. Dose adjustments to diabetes medications might be necessary.

Likelihood Possible Evidence B
Hepatotoxic Drugs

Theoretically, large doses of cassia cinnamon might cause additive effects when used with hepatotoxic drugs.
There is some concern that ingesting large amounts of cassia cinnamon for an extended duration might cause hepatotoxicity in some people. Cassia cinnamon contains coumarin, which can cause hepatotoxicity in animal models. In humans, very high doses of coumarin from 50-7000 mg/day can result in hepatotoxicity that resolves when coumarin use is discontinued. Lower amounts might also cause liver problems in sensitive people, such as those with liver disease or those taking potentially hepatotoxic agents.

Likelihood Possible Evidence D

Rehmannia root extract2 drug types · 258 drugs

Antidiabetes Drugs

Theoretically, rehmannia might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research shows that rehmannia may have hypoglycemic effects.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, rehmannia might increase the risk of hypotension when taken with antihypertensive drugs.
Animal research shows that rehmannia may have hypotensive effects. Laboratory research shows that formulations of dried and processed rehmannia root inhibit angiotensin-converting enzyme (ACE).

Likelihood Possible Evidence D

Pumpkin1 drug type · 1 drug

Lithium

Pumpkin might reduce excretion and increase levels of lithium.
Pumpkin is thought to have diuretic properties. Theoretically, this might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Urgent-Less by Priority One Nutritional Supplements: Common Questions

Does Urgent-Less by Priority One Nutritional Supplements interact with any medications?
Yes. Based on its ingredients, Urgent-Less has a known interaction with 933 medications, including 9 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Urgent-Less contains 5 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
Is it safe to use Urgent-Less while pregnant?
No. Buchu and rehmannia should be avoided in pregnancy due to insufficient safety data. Cinnamon at medicinal doses should also be avoided. While pumpkin as a food is fine and soy foods are normally eaten in pregnancy, the concentrated ingredients in this supplement haven't been well studied in pregnancy. Talk with your doctor or pharmacist before taking it.
What is pumpkin in this product supposed to do?
Pumpkin has possibly effective evidence for benign prostate enlargement. The ingredient here appears to be pumpkin seed extract. Most other claimed uses for pumpkin—hair loss, bladder issues, UTIs—have insufficient evidence in our data.
What does soy do in Urgent-Less?
Soy in this product provides protein and isoflavones (plant compounds with weak estrogen-like activity) with possibly effective evidence for lowering blood sugar, cholesterol, and blood pressure, plus supporting bone health and reducing diarrhea. But soy also carries several moderate medication interactions and one major interaction with MAOIs.
Is cinnamon in this product effective for blood sugar?
No. The evidence for cinnamon lowering blood sugar is insufficient to rate it. While it may have some blood-sugar-lowering effect, there isn't enough reliable evidence to claim it works for diabetes. However, it does interact with diabetes medications, so it still warrants caution.
What are the most common side effects?
The ingredients most likely to cause side effects are soy (bloating, constipation, diarrhea, nausea, or allergic reactions) and pumpkin (abdominal discomfort, diarrhea, nausea, or vomiting). A rash was reported in one person taking cinnamon in a trial. Most people tolerate these ingredients without problems.
Is Urgent-Less safe while breastfeeding?
Probably not without medical approval. Buchu and rehmannia should be avoided while breastfeeding due to insufficient safety data. Pumpkin and soy as foods are commonly eaten while breastfeeding, but concentrated supplements haven't been well studied. Talk with your doctor or pharmacist.
