American White Water Lily and Vibegron

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Vibegron and American White Water Lily in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for American White Water Lily at all — not against Vibegron, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

What Vibegron’s Own FDA Label Lists

This is not an interaction — none of it involves American White Water Lily. These are the most notable effects listed in the ADVERSE REACTIONS section of Vibegron’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 2 of them are worth acting on rather than waiting out — marked below.

  • Trouble passing urine Worth acting on mentioned in 3.9% of FDA reports for Vibegron
  • A higher chance of infection Worth acting on mentioned in 4.4% of FDA reports for Vibegron
  • Diarrhea mentioned in 5.0% of FDA reports for Vibegron
  • Headache mentioned in 4.8% of FDA reports for Vibegron
  • Nausea

From the ADVERSE REACTIONS section of the FDA label for Vibegron. Read the label on DailyMed › Where a percentage is shown, it is the share of 7,142 voluntary FDA FAERS reports for Vibegron that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. American White Water Lily’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no American White Water Lily side to compare — that is a limit of the record, not a statement that American White Water Lily has no side effects.

“Three items on this page deserve more attention than the other 154 combined for anyone taking vibegron (Gemtesa) for overactive bladder. Grapefruit can raise the drug's blood level by blocking the enzyme that clears it, St.”

About American White Water Lily

What is American White Water Lily?

American White Water Lily
  • Sore throat and mouth irritation
  • Vaginal irritation (as a wash or douche)
  • Skin sores, burns, and boils (topical poultice)
  • Diarrhea (astringent)
  • Minor wound care

American white water lily is a North American aquatic plant whose root has a long history of traditional use, mostly as an astringent for skin, mouth, and vaginal complaints. There is very little modern human research to confirm any of these uses, so it should be viewed as a folk remedy rather than a proven treatment. Talk to your pharmacist or doctor before using it, and avoid it if you are pregnant or breastfeeding.

Nymphaea odorata · Nymphaeaceae · Rhizome (root) and flowers; sometimes leaves · Dried root, powder, tea, liquid extract, poultice, and topical washes or gargles

An interaction check asks whether these two react with each other — it does not ask whether American White Water Lily is a good idea for someone in your situation. Here is what our American White Water Lily record says about it on its own.
