Drug & supplement interaction

Shiatsu + Chlorpromazine

Chlorpromazine brand names: Thorazine, Thorazine Spansules.

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 Shiatsu and Chlorpromazine 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

Shiatsu and Chlorpromazine

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 Chlorpromazine and Shiatsu in our sources. This does not guarantee that the combination is completely free of risk — research on Shiatsu alongside specific medications may be limited.

Worth understanding: our licensed dataset holds no drug-interaction record for Shiatsu at all — not against Chlorpromazine, 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.

Shiatsu is a treatment rather than something you take. Tell whoever provides it which medicines you use, and ask your prescriber whether it is appropriate for your health and treatment. 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 Shiatsu and Chlorpromazine May Share a Side Effect

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 having Shiatsu while taking the medicine can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • Dizziness Additional detail

    Shiatsu

    “In one report, a 56-year-old Japanese woman developed neck pain, dizziness, dysphagia, and gait disturbance during shiatsu treatment. Diagnostic tests showed right vertebral artery stenosis and cerebellar infarction likely related to shiatsu treatment. In other case reports, shiatsu massage of the neck resulted in cerebral artery embolism and a jugular vein thrombosis.”

    Listed in the ADVERSE REACTIONS section of the FDA label for Chlorpromazine. Read the label on DailyMed ›

Reported for Shiatsu but not commonly for Chlorpromazine: unsteadiness, blood clots and trouble swallowing.

Effects for Chlorpromazine come from the ADVERSE REACTIONS section of its FDA label; effects for Shiatsu come from the Natural Medicines adverse-effect record, quoted above. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Chlorpromazine Is Prescribed For, and What Shiatsu Has Been Studied For

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

Chlorpromazine is prescribed for: Chlorpromazine is used to manage psychotic disorders and treat schizophrenia. It also controls nausea and vomiting, relieves restlessness and apprehension before surgery, and controls the manic phase of manic-depressive illness. Other uses include relief of intractable hiccups, treatment of acute intermittent porphyria, and use as an adjunct in tetanus treatment. In children ages 1 to 12, it is used for severe behavioral problems marked by explosive or combative behavior, and for short-term treatment of hyperactive children with conduct disorders.

Read the rest of what Chlorpromazine is prescribed for

The oral forms are also approved for the management of manifestations of psychotic disorders broadly, in addition to the uses shared with the injection form.

Shiatsu has been studied for:

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

    Shiatsu for schizophrenia

    A small, low quality clinical study shows that shiatsu massage given as 8 sessions biweekly for 4 weeks can improve negative affect, psychosis, depression, and anxiety in patients with schizophrenia when compared to baseline. The validity of these findings is limited by small study size and the lack of a comparator group.

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 Chlorpromazine on your own; if you are taking Shiatsu for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Shiatsu

What is Shiatsu?

  • Stress and relaxation
  • Muscle tension and stiffness
  • Low back and neck pain
  • Headaches
  • General well-being
  • Sleep problems

Shiatsu is a Japanese form of massage and bodywork, not a herb or dietary supplement, so it is not something you swallow. Many people find it relaxing and helpful for stress and muscle tension, but high-quality research on its health benefits is limited. It is generally low-risk for most people when done by a trained practitioner, but talk with your doctor first if you have a medical condition.

Not applicable — Shiatsu is a hands-on therapy, not a plant or supplement · In-person bodywork sessions performed by a trained practitioner

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

Shiatsu: dosing

Because Shiatsu is a hands-on therapy and not something you swallow, there is no dose in milligrams or pills. Sessions usually last around 30 to 60 minutes, and how often people go varies widely based on their goals and comfort.There is no standard "prescription" for how many sessions are needed. If you want to try Shiatsu, choose a qualified practitioner, start slowly, and discuss your health history with them.

Having Shiatsu While Taking Chlorpromazine: Common Questions

Is it safe to have Shiatsu while taking Chlorpromazine?
We do not list a known interaction between Shiatsu and Chlorpromazine. 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 Shiatsu and Chlorpromazine have any of the same side effects?
Yes — our sources link each of them separately to one 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 Shiatsu and Chlorpromazine 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 Shiatsu in each. That is a conversation for your prescriber, especially if Chlorpromazine is being adjusted to a target.
Does Chlorpromazine interact with any supplements?
Yes. Chlorpromazine has documented interactions with 211 supplements in our database — Shiatsu is not one of them. The Chlorpromazine interaction page linked on this page lists every one, ranked by severity.
