Cudweed and Flibanserin

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 Flibanserin and Cudweed 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.

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.

Cudweed overall Not established Limited modern safety data exist, so use with caution and talk to a healthcare provider first.

How we checked

Why No Interaction Is Listed for Flibanserin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Flibanserin is filed under 5 classifications — including cytochrome p450 2c19 (cyp2c19) substrates, cns depressants, cytochrome p450 3a4 (cyp3a4) substrates. Cudweed has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Flibanserin’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What Flibanserin’s Own FDA Label Lists

This is not an interaction — none of it involves Cudweed. These are the most notable effects listed in the ADVERSE REACTIONS section of Flibanserin’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.

  • Fainting Worth acting on
  • A higher chance of infection Worth acting on
  • Drowsiness mentioned in 8.4% of FDA reports for Flibanserin
  • Trouble sleeping mentioned in 7.1% of FDA reports for Flibanserin
  • Dizziness mentioned in 16.6% of FDA reports for Flibanserin
  • Dry mouth
  • Low blood pressure
  • Anxiety or restlessness
  • Tiredness mentioned in 7.1% of FDA reports for Flibanserin
  • Constipation

Showing the 10 most notable of 11 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Flibanserin. Read the label on DailyMed › Where a percentage is shown, it is the share of 1,994 voluntary FDA FAERS reports for Flibanserin that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Cudweed’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Cudweed side to compare — that is a limit of the record, not a statement that Cudweed has no side effects.

From our pharmacist’s overview on the Flibanserin page

“Flibanserin (Addyi) is a nightly pill for low sexual desire in premenopausal women, and because it is sedating and can lower blood pressure, its supplement list deserves genuine care; nine of the 199 entries rate major, and those are the ones to learn first. Seventy-eight ingredients have calming effects that stack with flibanserin's d…”

About Cudweed

What is Cudweed?

  • Mouth and throat irritation
  • Digestive upset
  • Mild high blood pressure (traditional)
  • Minor wounds and skin irritation
  • Coughs and respiratory complaints

Cudweed is a small, woolly-leaved plant used in traditional herbal medicine, mainly as a tea or gargle for sore throats, digestive upset, and minor skin problems. There is very little modern scientific evidence to confirm that it works for any condition, and safety data are limited, so it is best used cautiously and avoided in pregnancy and breastfeeding.

Gnaphalium uliginosum · Asteraceae · Aerial parts (flowering tops, leaves, and stems) · Tea (infusion), tincture, dried herb

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

Cudweed: dosing

There is no established or standardized dose for cudweed. It has not been studied enough to know a safe and effective amount, and traditional preparations vary.If you choose to use a commercial product, follow the directions on the label and do not exceed the recommended amount.
