No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Hedge-hyssop and Nizatidine 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

Hedge-hyssop and Nizatidine

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 Nizatidine and Hedge-hyssop 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 Hedge-hyssop at all — not against Nizatidine, 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 Hedge-hyssop and Nizatidine 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.

  • Vomiting / Diarrhea reported in 4.3% of FDA reports for Nizatidine Additional detail

    Hedge-hyssop

    “Orally, taken in toxic doses, hedge-hyssop may cause vomiting, bloody diarrhea, colic, and kidney irritation characterized by initial diuresis followed by anuria. When people ingest very large amounts, spasms, paralysis, and circulatory collapse occur. Death occurs rarely (18).”

    Nizatidine

    Listed in the ADVERSE REACTIONS section of the FDA label for Nizatidine, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for Hedge-hyssop but not commonly for Nizatidine: passing urine more often.

Effects for Nizatidine come from the ADVERSE REACTIONS section of its FDA label; effects for Hedge-hyssop come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 1,518 voluntary FDA FAERS reports for Nizatidine 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.

Everything else you take

See Every Supplement That Interacts With Nizatidine

This page covers Hedge-hyssop only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Nizatidine page lists 31 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Beer (moderate), Coffee Charcoal (moderate), European Mandrake (moderate) and Glucomannan (moderate).

By severity: 1 major · 9 moderate · 21 minor.

From our pharmacist’s overview on the Nizatidine page

“Nizatidine (Axid) reduces stomach acid to treat heartburn and ulcers, and its supplement list earns real attention rather than a passing glance. The one major-rated entry is activated charcoal, which can soak up the drug in the gut and cut how much reaches your bloodstream.”

About Hedge-hyssop

What is Hedge-hyssop?

  • Constipation and as a laxative
  • Fluid retention (diuretic use)
  • Liver and digestive complaints
  • Skin conditions (traditional/topical)
  • Inducing vomiting (historical purgative)

Hedge-hyssop is a traditional European herb that was historically used as a strong laxative, diuretic, and purgative, but it is considered toxic and is not recommended for self-treatment. There is no reliable modern evidence that it is safe or effective, and serious poisoning has been reported, so it is best avoided.

Gratiola officinalis · Plantaginaceae · Aerial parts (leaves and flowering stems), sometimes the root · Dried herb, tincture, and historically homeopathic preparations

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

Hedge-hyssop: dosing

There is no established safe or standardized dose of hedge-hyssop. Because the plant is toxic and the margin between a traditional dose and a harmful dose is narrow, no specific amount can be recommended.We do not advise self-treating with this herb.

About Nizatidine

What Is Nizatidine Used For?

Brand names: Axid, Axid Injection

Nizatidine treats conditions caused by too much stomach acid. Both the capsule and oral solution are approved to treat active duodenal ulcers (ulcers in the small intestine) and active benign gastric ulcers (stomach ulcers), and to manage gastroesophageal reflux disease (GERD), including erosive and ulcerative esophagitis (inflammation and damage to the esophagus) and related heartburn.

After a duodenal ulcer heals, nizatidine can be continued at a lower dose to help prevent the ulcer from coming back. Nizatidine oral solution is also approved for adolescents 12 years of age and older for GERD and erosive esophagitis. Before treating a stomach ulcer, your doctor will rule out stomach cancer, since the symptoms can overlap.

Most-Reported Side Effects for Nizatidine

From FAERS, the FDA’s public side-effect reporting system (1,518 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Chronic kidney disease 264 reports
Acute kidney injury 161 reports
Renal failure 138 reports
Nausea 73 reports
End stage renal disease 72 reports
