Drug & supplement interaction

Roman Chamomile + Desmopressin Acetate

Desmopressin Acetate brand names: DDAVP, Noctiva, Nocdurna.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Roman Chamomile and Desmopressin Acetate 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. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Roman Chamomile and Desmopressin Acetate

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 Desmopressin Acetate and Roman Chamomile 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 Roman Chamomile at all — not against Desmopressin Acetate, 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 to actually watch for

No Interaction Found — But Data Suggests Roman Chamomile and Desmopressin Acetate May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

  • An allergic reaction Worth acting on Additional detail

    Roman Chamomile

    “Topically, Roman chamomile can cause contact dermatitis (4,567,97292). Allergic skin reactions can occur in up to 20% of individuals exposed to Roman chamomile (19). Multiple case reports have described the development of topical allergic reactions, including eczema and rash, with the use of cleaning products and cosmetics containing chamomile oil or chamomile extract.”

Reported for Roman Chamomile but not commonly for Desmopressin Acetate: a skin rash and vomiting.

Effects for Desmopressin Acetate come from the ADVERSE REACTIONS section of its FDA label; effects for Roman Chamomile come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 3,776 voluntary FDA FAERS reports for Desmopressin Acetate that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Special populations

Roman Chamomile in Pregnancy & Breastfeeding

Pregnancy Likely Unsafe

Overlapping uses

What Desmopressin Acetate Is Prescribed For, and What Roman Chamomile Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Desmopressin Acetate is a prescription medicine with approved uses on its FDA label. Roman Chamomile is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Desmopressin Acetate is prescribed for: Desmopressin treats central diabetes insipidus — a condition where the body doesn't make enough antidiuretic hormone (ADH), causing the kidneys to release far too much water. It's also used for temporary excessive urination and thirst that can follow head trauma or surgery near the pituitary gland. It's also approved for primary nocturnal enuresis (bedwetting at night) and can be used alone or alongside behavioral approaches. Note: it does not work for nephrogenic diabetes insipidus, a different type of the condition.

Roman Chamomile has been studied for:

  • Diabetes studied, not established Roman Chamomile has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Roman Chamomile for diabetes

    Although there is interest in using oral Roman chamomile for diabetes, there is insufficient reliable information about the clinical effects of Roman chamomile for this condition.

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 Desmopressin Acetate on your own; if you are taking Roman Chamomile for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Desmopressin Acetate page

“Every one of the 17 supplements flagged for desmopressin acetate (DDAVP, Nocdurna, Noctiva) works the same basic way, by changing how much of the drug is absorbed from the gut, and that deserves real attention. Desmopressin controls urine output in diabetes insipidus and nighttime urination, and only a small fraction of an oral dose re…”

About Roman Chamomile

What is Roman Chamomile?

  • Digestive upset
  • Anxiety and relaxation
  • Sleep support
  • Skin irritation
  • Menstrual cramps

Roman chamomile is a daisy-family herb used traditionally as a calming tea and as an oil for digestion, mild anxiety, and skin comfort. Solid human evidence is limited for most uses, but it is generally considered safe in food and tea amounts for most adults. People allergic to ragweed and related plants should be cautious, and pregnant or breastfeeding people should check with a doctor first.

Chamaemelum nobile · Asteraceae · Flowers (and essential oil) · Tea, capsules, liquid extract, essential oil, topical creams

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

Roman Chamomile: dosing

There is no official standardized dose for Roman chamomile. The amount varies widely depending on the product and the form (tea, capsule, or extract).A common traditional use is one cup of chamomile tea made from the dried flowers, taken up to a few times a day. For capsules or liquid extracts, follow the directions on the product label, since strengths differ between brands.

Taking Roman Chamomile and Desmopressin Acetate Together: Common Questions

Is it safe to take Roman Chamomile with Desmopressin Acetate?
We do not list a known interaction between Roman Chamomile and Desmopressin Acetate. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Roman Chamomile and Desmopressin Acetate have any of the same side effects?
Yes — our sources link each of them separately to 3 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Are Roman Chamomile and Desmopressin Acetate used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Roman Chamomile in each. That is a conversation for your prescriber, especially if Desmopressin Acetate is being adjusted to a target.
Does Desmopressin Acetate interact with any supplements?
Yes. Desmopressin Acetate has documented interactions with 17 supplements in our database — Roman Chamomile is not one of them. The Desmopressin Acetate interaction page linked on this page lists every one, ranked by severity.
