Quince + Chlordiazepoxide, Clidinium Bromide
Chlordiazepoxide, Clidinium Bromide brand name: Librax.
We found no known interaction between Quince and Chlordiazepoxide, Clidinium Bromide in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.
Quince and Chlordiazepoxide, Clidinium Bromide
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 Chlordiazepoxide, Clidinium Bromide and Quince 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 Quince at all — not against Chlordiazepoxide, Clidinium Bromide, 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 Chlordiazepoxide, Clidinium Bromide Is Prescribed For, and What Quince Has Been Studied For
These two come up together because they touch the same health topic — not because they do the same job. Chlordiazepoxide, Clidinium Bromide is a prescription medicine with approved uses on its FDA label. Quince is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.
Chlordiazepoxide, Clidinium Bromide is prescribed for: Chlordiazepoxide and clidinium capsules are used to help control both the physical and emotional factors involved in gastrointestinal (digestive) disorders. This includes use as add-on therapy for peptic ulcer, irritable bowel syndrome (also called irritable colon, spastic colon, or mucous colitis), and acute enterocolitis (sudden inflammation of the intestines). Librax is one brand available in capsule form and is approved for the same set of gastrointestinal uses.
Quince has been studied for:
-
Peptic ulcers studied, not established Quince has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows
Quince for peptic ulcers
Although there has been interest in using oral quince for peptic ulcers, there is insufficient reliable information about the clinical effects of quince for this purpose.
Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Chlordiazepoxide, Clidinium Bromide on your own; if you are taking Quince for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Quince
What is Quince?
- Digestive upset and diarrhea
- Acid reflux and heartburn
- Sore throat and cough
- Skin soothing and wound care
- Nausea
Quince is a tart, apple-like fruit traditionally used for digestive complaints, reflux, and soothing the throat and skin. Early research is interesting but limited, so quince should not replace proven treatments. Enjoying cooked quince in food is generally fine, but talk to a pharmacist or doctor before using concentrated supplements.
Cydonia oblonga · Rosaceae · Fruit, seeds, and leaves · Fresh fruit, jam or jelly, syrup, tea, dried seeds, capsules, extracts
An interaction check asks whether these two react with each other — it does not ask whether Quince is a good idea for someone in your situation. Here is what our Quince record says about it on its own.
Quince: dosing
There is no standardized or proven dose for quince supplements. The right amount depends on the product, the part of the plant used, and how it is prepared, which varies a lot between brands.If you choose to use a quince product, follow the directions on the label and do not exceed the suggested amount. Avoid eating raw or crushed seeds.
