The bottom line No known interaction

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.

Kampo Medicine and Rabeprazole Sodium

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 Rabeprazole Sodium and Kampo Medicine 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 Kampo Medicine at all — not against Rabeprazole Sodium, 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.

Kampo Medicine safety at a glance

Kampo Medicine overall Use caution Generally considered low-risk when used appropriately, but multi-herb formulas can cause side effects and quality varies by product.
Pregnancy Avoid Many formulas contain herbs not proven safe in pregnancy, so avoid unless directed by a qualified clinician.
Breastfeeding Use caution Safety during breastfeeding is not well established, so use only with professional guidance.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What Rabeprazole Sodium’s Own FDA Label Lists

This is not an interaction — none of it involves Kampo Medicine. These are the most notable effects listed in the ADVERSE REACTIONS section of Rabeprazole Sodium’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. 4 of them are worth acting on rather than waiting out — marked below.

  • Kidney problems Worth acting on mentioned in 40.5% of FDA reports for Rabeprazole Sodium
  • Low magnesium Worth acting on
  • Bone thinning Worth acting on
  • A higher chance of infection Worth acting on
  • Heartburn
  • Bloating or gas
  • Sore throat
  • Constipation
  • Stomach pain
  • Diarrhea mentioned in 4.4% of FDA reports for Rabeprazole Sodium

Showing the 10 most notable of 13 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 Rabeprazole Sodium. Read the label on DailyMed › Where a percentage is shown, it is the share of 26,951 voluntary FDA FAERS reports for Rabeprazole Sodium that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Kampo Medicine’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Kampo Medicine side to compare — that is a limit of the record, not a statement that Kampo Medicine has no side effects.

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Kampo Medicine 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 Kampo Medicine reference on this page ↓

About Kampo Medicine

What is Kampo Medicine?

  • Digestive complaints
  • Cold and flu symptoms
  • Menopausal symptoms
  • Fatigue and general weakness
  • Constipation
  • Pain and inflammation

Kampo is a traditional Japanese system of herbal medicine that uses standardized multi-herb formulas, many of which are prescribed by doctors in Japan. Some formulas have modest supportive evidence for certain conditions, but quality and strength of research vary widely. Because Kampo products combine many ingredients, talk with a pharmacist or doctor before using them, especially if you take other medicines or have a health condition.

Roots, rhizomes, bark, leaves, flowers, fruits, seeds, and minerals depending on the formula · Granules, powders, decoctions (teas), tablets, and capsules

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

Kampo Medicine: dosing

There is no single standard dose for "Kampo medicine" because it is a whole system of many different formulas. Each formula has its own typical dosing, which can also depend on the person and the condition being treated.In Japan, doses are often based on standardized extract granules and prescribed by a clinician.

About Rabeprazole

What Is Rabeprazole Used For?

Brand names: Aciphex, Aciphex Sprinkle

Rabeprazole delayed-release tablets treat a range of acid-related conditions in adults, including healing and maintenance of erosive or ulcerative GERD (gastroesophageal reflux disease), symptomatic GERD, duodenal ulcers, and pathological hypersecretory conditions such as Zollinger-Ellison syndrome. They are also used alongside antibiotics (amoxicillin and clarithromycin) to eradicate H. pylori bacteria and reduce the risk of duodenal ulcer coming back.

In adolescents 12 years and older, rabeprazole delayed-release tablets are approved for short-term treatment of symptomatic GERD. Both AcipHex and Rabeprazole Sodium delayed-release tablets share this indication set for adults and adolescents 12 and older.
