Drug & supplement interaction

Poison Ivy + Mometasone

Mometasone brand names: Elocon, Asmanex.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Poison Ivy and Mometasone 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.

Interaction report

Poison Ivy and Mometasone

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 Mometasone and Poison Ivy 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 Poison Ivy at all — not against Mometasone, 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 Poison Ivy and Mometasone 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.

  • A higher chance of infection Worth acting on Additional detail

    Poison Ivy

    “Inhaled, urushiol in the smoke from burning of poison ivy can result in life-threatening throat swelling, fever, and secondary lung infections (6). Respiratory distress syndrome after smoke inhalation from burning poison ivy has also been reported. Two fatal cases of acute respiratory distress and anaphylaxis after inhaling burned poison ivy are reported in patients with known allergies to poison ivy.”

    “Topically, poison ivy can cause contact dermatitis, reddening, swelling, and herpes-like blisters (18). These reactions occur at the area of contact, usually within a few hours, but are sometimes delayed for several days. Sometimes papules and vesicles develop and can spread beyond the area of initial contact, but are generally self-limiting and eventually form crusts..”

Overlapping uses

What Mometasone Is Prescribed For, and What Poison Ivy Has Been Studied For

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

Mometasone is prescribed for: Mometasone Furoate topical products are used to relieve the inflammation and itching (pruritus) that come with corticosteroid-responsive dermatoses — a broad category of skin conditions that respond to steroid treatment. Mometasone Furoate Topical Solution (Lotion) is specifically indicated for these skin conditions in patients 12 years of age and older. Mometasone Furoate cream may be used in adults and in children 2 years of age and older.

Poison Ivy has been studied for:

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

    Poison Ivy for pruritus

    Although there has been interest in using oral homeopathic preparations of poison ivy for pruritic skin conditions, there is insufficient reliable evidence about the clinical effects of poison ivy 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 Mometasone on your own; if you are taking Poison Ivy for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Poison Ivy

What is Poison Ivy?

  • Joint pain and stiffness
  • Muscle soreness or strains
  • Skin rashes and itching
  • Arthritis discomfort
  • Restlessness with body aches

Poison ivy is a toxic plant best known for causing an itchy, blistering allergic rash on contact. In supplement form it is sold almost exclusively as an extremely dilute homeopathic remedy (Rhus tox) for joint and muscle pain, but reliable evidence that it works is lacking, and the raw plant should never be used or ingested.

Toxicodendron radicans · Anacardiaceae · Leaves, stems, and root (used in highly diluted homeopathic preparations); fresh plant in traditional use · Homeopathic pellets, tablets, and topical preparations (sold as 'Rhus tox' or 'Rhus toxicodendron')

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

Poison Ivy: dosing

There is no established, science-based dose for poison ivy. The raw plant has no safe oral or topical dose and should never be used.Homeopathic Rhus tox is sold in various "potencies" (such as 6C or 30C) and forms, including pellets and tablets.

Taking Poison Ivy and Mometasone Together: Common Questions

Is it safe to take Poison Ivy with Mometasone?
We do not list a known interaction between Poison Ivy and Mometasone. 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 Poison Ivy and Mometasone have any of the same side effects?
Yes — our sources link each of them separately to 2 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 Poison Ivy and Mometasone 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 Poison Ivy in each. That is a conversation for your prescriber, especially if Mometasone is being adjusted to a target.
Does Mometasone interact with any supplements?
Yes. Mometasone has documented interactions with 141 supplements in our database — Poison Ivy is not one of them. The Mometasone interaction page linked on this page lists every one, ranked by severity.
