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 7 of its 7 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Sundown Water Pills contains 7 active ingredients: parsley, potassium, asparagus, juniper extract, uva ursi extract, buchu extract, and alfalfa. These are combined with inactive ingredients like vegetable cellulose, calcium carbonate, dextrates, and silica that serve as fillers and binders.

Parsley, asparagus, juniper, and uva ursi are all traditionally used as herbal diuretics intended to increase urine output. Buchu extract and alfalfa are included for similar purposes.

Potassium is added to help replace electrolytes that are lost when you urinate more frequently.

Does it work?

Evidence for Intended Use · database check

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: Diuretic support and urinary tract health.
  • We looked for evidence on: Urinary tract infections (UTIs), Kidney stones (nephrolithiasis), fluid retention, bloating, urinary discomfort.
  • The closest evidence on file: Uva Ursi is rated "Possibly Ineffective" for Urinary tract infections (UTIs) (Natural Medicines).
  • Also on file: Asparagus is rated "Insufficient Reliable Evidence To Rate" for Kidney stones (nephrolithiasis), Urinary tract infections (UTIs).
  • Also on file: Juniper is rated "Insufficient Reliable Evidence To Rate" for Kidney stones (nephrolithiasis), Urinary tract infections (UTIs).

The evidence for what this product actually does is limited. Our data holds no effectiveness ratings for potassium, buchu, or the genistein we could not check.

Parsley, asparagus, juniper, uva ursi, and alfalfa are all listed with insufficient evidence for their claimed uses — meaning studies to date haven't established whether they work. Uva ursi is specifically rated possibly ineffective for urinary tract infections (UTIs), one reason people buy water pills.

The evidence, ingredient by ingredient Parsley Potassium Asparagus Juniper Uva Ursi Buchu Alfalfa

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 6 of the 7 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 7 of 7.
  • General safety write-ups exist for 7 of 7.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Parsley is generally well tolerated at the food amounts most people eat, but concentrated extracts and large doses can cause serious effects including hemolytic anemia (a breakdown of red blood cells), low blood pressure, and kidney damage at very high intakes — 200 grams of parsley oil or 10 grams or more of its toxic constituent apiole. Potassium from food is safe, but supplements can dangerously raise your blood potassium level, especially if you have kidney disease.

Juniper should not be used during pregnancy — safety data are lacking — and long-term medicinal use may irritate the kidneys. Uva ursi is generally tolerated short-term at low doses but can cause collapse, convulsions, and shortness of breath at high doses (20 grams or more).

Alfalfa has estrogen-like activity and is best avoided in supplement amounts during pregnancy. Buchu lacks strong safety data at medicinal doses.

Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 7 of the 7 matched ingredients can interact with medications — Alfalfa, Buchu, Asparagus, Uva Ursi, Juniper, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; lithium.
  • For scale: 1,379 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 this product, check your medications with your pharmacist if you take: blood thinners or antiplatelet drugs (aspirin, clopidogrel, warfarin — Major risk with alfalfa and warfarin specifically), diabetes medications, blood pressure drugs (ACE inhibitors, ARBs, diuretics), lithium, or any drugs metabolized by your liver. The potassium in this product can dangerously raise your blood potassium level if combined with certain blood pressure or heart medications.

The bottom line

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

If you take blood thinners, diabetes medications, blood pressure drugs, lithium, or any prescription medication, talk to your pharmacist before starting this product — the interaction risks are real and potentially serious. Even if you don't take those specific drugs, run your full medication list through the checker below.

The evidence that this product actually works is insufficient, and several ingredients carry safety concerns at high doses or with long-term use.

Each ingredient & the kinds of drugs it affects

For each ingredient in Water Pills 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.

Uva Ursi extract6 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.

Likelihood Possible Evidence D
Uva Ursi extract full monograph & interactions

Alfalfa6 drug types · 583 drugs

Warfarin (Coumadin)

Theoretically, alfalfa might reduce the anticoagulant activity of warfarin.
Alfalfa contains a large amount of vitamin K. This could theoretically interfere with the activity of warfarin.

Likelihood Probable Evidence D
Antidiabetes Drugs

Theoretically, alfalfa might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research suggests that alfalfa decreases blood sugar in diabetic mice. Also, in one case report, a diabetic patient experienced hypoglycemia after consuming alfalfa extract. Monitor blood glucose levels closely. Dose adjustments might be necessary.

Likelihood Possible Evidence D
Contraceptive Drugs

Theoretically, alfalfa might interfere with the activity of contraceptive drugs.
Alfalfa contains coumestrol, a phytoestrogen, and isoflavonoids, which have estrogenic effects.

Likelihood Possible Evidence D
Estrogens

Theoretically, alfalfa might interfere with hormone therapy.
Alfalfa contains coumestrol, a phytoestrogen, and isoflavonoids, which have estrogenic effects.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, alfalfa might decrease the efficacy of immunosuppressive therapy.
In vitro research and human case reports suggest that alfalfa may have immunostimulant effects.

Likelihood Possible Evidence D
Photosensitizing Drugs

Theoretically, concomitant use of alfalfa with photosensitizing drugs might have additive effects.
Animal research suggests that excessive doses of alfalfa may increase photosensitivity, possibly due to its chlorophyll content. It is unclear if this effect would be clinically relevant in humans.

Likelihood Possible Evidence D
Alfalfa full monograph & interactions

Buchu 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

Parsley8 drug types · 443 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, parsley might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Animal research suggests that parsley has antiplatelet effects.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, parsley might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research suggests that parsley might decrease blood glucose. Monitor blood glucose levels closely. Dose adjustments might be necessary.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, parsley might increase serum levels of CYP1A2 substrates.
Laboratory research suggests that parsley can inhibit CYP1A2.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, parsley might enhance or interfere with the effects of diuretic drugs.
Animal research suggests that parsley seed extract increases urine elimination. Parsley leaf and root might also interfere with diuretic therapy due their purported aquaretic effects.

Likelihood Possible Evidence D
Pentobarbital (Nembutal)

Theoretically, parsley might increase the duration of pentobarbital effects.
Animal research suggests that parsley juice prolongs the action of pentobarbital, perhaps by decreasing cytochrome P450 levels. It is not known if this occurs in humans or if this applies to other barbiturates or sedatives.

Likelihood Possible Evidence D
Sirolimus (Rapamune)

Theoretically, large quantities of parsley might increase sirolimus levels.
In one case report, an adult female with a history of kidney transplant presented with elevated blood sirolimus levels, approximately 4-7 times greater than previous measures, after daily consumption of a juice containing approximately 30 grams of parsley for 7 days. Sirolimus levels returned to normal a week after the parsley juice was discontinued.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, large amounts of parsley leaf and root might decrease the effects of warfarin.
Parlsey contains vitamin K.

Likelihood Possible Evidence D
Aspirin

Theoretically, aspirin might increase the severity of allergic reactions to parsley.
In one case, severe urticaria and swelling were reported after taking aspirin with parsley in an individual with a known mild parsley allergy.

Animal studies show that asparagus root extracts have diuretic effects. This effect has not been reported in humans.

Likelihood Possible Evidence D
Lithium

Theoretically, asparagus root might cause diuresis, reducing lithium clearance.
Animal studies show that asparagus root extracts have diuretic effects. Theoretically, this might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Likelihood Probable Evidence D
Asparagus full monograph & interactions

Potassium3 drug types · 62 drugs

Ace Inhibitors (Aceis)

Using ACEIs with high doses of potassium increases the risk of hyperkalemia.
ACEIs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.

Likelihood Likely Evidence C
Angiotensin Receptor Blockers (Arbs)

Using ARBs with high doses of potassium increases the risk of hyperkalemia.
ARBs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.

Likelihood Likely Evidence C
Potassium-Sparing Diuretics

Concomitant use increases the risk of hyperkalemia.
Using potassium-sparing diuretics with potassium supplements increases the risk of hyperkalemia.

Water Pills by Sundown: Common Questions

Does Water Pills by Sundown interact with any medications?
Yes. Based on its ingredients, Water Pills has a known interaction with 1,378 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Water Pills contains 7 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.
Does this actually help you lose water weight or treat bloating?
Our data doesn't show established evidence that the herbal diuretics in this product work for water retention or bloating. Several of the ingredients — parsley, asparagus, juniper, uva ursi — are traditionally used as diuretics, but clinical evidence supporting their effectiveness is insufficient.
Is it safe to take this while pregnant?
No. Alfalfa is rated possibly unsafe in pregnancy and is best avoided in supplement amounts. Juniper should be avoided during pregnancy. Parsley in large medicinal amounts may stimulate the uterus. If you're pregnant, don't take this product — talk to your doctor or midwife first.
Can I take this while breastfeeding?
There isn't enough safety data on medicinal doses of juniper, uva ursi, buchu, or alfalfa during breastfeeding, so they're best avoided. Talk to your doctor or pharmacist for personalized advice before taking this product while nursing.
What side effects should I watch for?
Common side effects from the herbal ingredients can include diarrhea, nausea, stomach upset, and flatulence. At normal doses, parsley and alfalfa are generally tolerated, but high doses of uva ursi or parsley can cause serious effects like convulsions, delirium, and kidney damage. If you experience unusual symptoms, stop and contact your doctor.
Why does this product contain potassium if it's a diuretic?
When you take a diuretic and urinate more, you lose electrolytes including potassium. The potassium in this product is meant to help replace what you lose. However, it can build up to dangerous levels, especially if you're taking certain blood pressure medications — which is why you need to check with your pharmacist first.
Is there anything in this I should avoid if I take warfarin or other blood thinners?
Yes. Alfalfa is high in vitamin K and can reduce warfarin's effectiveness. Parsley also contains vitamin K and may have the same effect. Additionally, both parsley and buchu may increase bleeding risk with blood thinners. Don't take this product with warfarin or other blood thinners without checking with your pharmacist first.
