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 Mezereon and Lisinopril 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.

Mezereon and Lisinopril

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 Lisinopril and Mezereon 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 Mezereon at all — not against Lisinopril, 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 Mezereon and Lisinopril 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.

About Mezereon

What is Mezereon?

  • Skin conditions and ulcers (traditional)
  • Joint and rheumatic pain (traditional)
  • Counter-irritant on the skin
  • Homeopathic remedies for skin eruptions

Mezereon is a poisonous European shrub whose bark and berries have been used in traditional and homeopathic medicine, but it is highly toxic and irritating. There is no reliable scientific evidence that it safely treats any condition, and swallowing any part of the plant can be dangerous. It should not be used as a home remedy.

Daphne mezereum · Thymelaeaceae · Bark and berries (rarely the dried bark used in traditional preparations) · Homeopathic preparations, traditional tinctures, and topical ointments

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

Mezereon: dosing

There is no established safe dose of mezereon for any medical use. Because the plant is poisonous, pharmacists and doctors do not recommend taking it.Highly diluted homeopathic products are sometimes sold, but these are not proven to work, and you should never use raw bark, berries, or homemade tinctures.

About Lisinopril

What Is Lisinopril Used For?

Brand names: Zestril, Prinivil, Qbrelis

Lisinopril treats high blood pressure (hypertension) in adults and children 6 years and older, and can be used alone or alongside other blood pressure medicines. Lowering blood pressure reduces the risk of strokes and heart attacks. The tablet combination product containing lisinopril and hydrochlorothiazide is specifically indicated for high blood pressure.

Lisinopril is also used as an add-on therapy to reduce signs and symptoms of systolic heart failure, and to reduce the risk of death in people who are hemodynamically stable (have reasonably stable circulation) within 24 hours of an acute heart attack (acute myocardial infarction).

Most-Reported Side Effects for Lisinopril

From FAERS, the FDA’s public side-effect reporting system (313,746 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 20,515 reports
Nausea 19,130 reports

Taking Mezereon and Lisinopril Together: Common Questions

Is it safe to take Mezereon with Lisinopril?
We do not list a known interaction between Mezereon and Lisinopril. 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 Mezereon and Lisinopril have any of the same side effects?
Yes — our sources link each of them separately to 7 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.
Does Lisinopril interact with any supplements?
Yes. Lisinopril has documented interactions with 167 supplements in our database — Mezereon is not one of them. The Lisinopril interaction page linked on this page lists every one, ranked by severity.
