Arenaria Rubra and Zonisamide

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 Zonisamide and Arenaria Rubra 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.

How we checked

Why No Interaction Is Listed for Zonisamide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Zonisamide is filed under 6 classifications — including dopamine agonists, anticonvulsants, cns depressants. Arenaria Rubra has documented interactions with 1 drug class — the most serious being acetylcholinesterase (ache) inhibitors (moderate) — and none of Zonisamide’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 to actually watch for

What Zonisamide’s Own FDA Label Lists

This is not an interaction — none of it involves Arenaria Rubra. These are the most notable effects listed in the ADVERSE REACTIONS section of Zonisamide’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. 9 of them are worth acting on rather than waiting out — marked below.

  • Seizures Worth acting on mentioned in 15.5% of FDA reports for Zonisamide
  • Kidney stones Worth acting on
  • Unsteadiness Worth acting on
  • Hallucinations Worth acting on
  • Confusion Worth acting on
  • A severe skin reaction Worth acting on
  • Low mood Worth acting on
  • Bleeding or bruising Worth acting on
  • An allergic reaction Worth acting on
  • Trouble concentrating

Showing the 10 most notable of 27 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 Zonisamide. Read the label on DailyMed › Where a percentage is shown, it is the share of 14,486 voluntary FDA FAERS reports for Zonisamide that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Arenaria Rubra’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Arenaria Rubra side to compare — that is a limit of the record, not a statement that Arenaria Rubra has no side effects.

Everything else you take

See Every Supplement That Interacts With Zonisamide

This page covers Arenaria Rubra only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Zonisamide page lists 206 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: 1,4-butanediol (major), Activated Charcoal (major), Beer (major), Gamma-hydroxybutyrate (ghb) (major) and Grapefruit (major).

By severity: 9 major · 157 moderate · 40 minor.

From our pharmacist’s overview on the Zonisamide page

“Zonisamide (Zonegran, Zonisade) keeps seizures under control, which means anything that shifts its blood level or stacks extra sedation on top deserves real respect, and nine of the 206 supplement ingredients on file rate major. Two big themes run through nearly everything here.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Arenaria Rubra is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Arenaria Rubra reference on this page ↓

About Arenaria Rubra

What is Arenaria Rubra?

Arenaria Rubra
  • Urinary and bladder complaints
  • Kidney stones ("stone-breaking")
  • Mild diuretic
  • Traditional digestive support
  • Antioxidant interest

Arenaria rubra (Spergularia rubra) is a small herb used in folk medicine, mainly for urinary and kidney complaints.

Talk with a pharmacist or doctor before using it, especially if you have a medical condition or are pregnant.

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