Drug & supplement interaction

Schizonepeta + Cinacalcet

Cinacalcet brand name: Sensipar.

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 Schizonepeta and Cinacalcet 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 label for Cinacalcet states a food rule worth keeping to, and 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.

Schizonepeta and Cinacalcet

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 Cinacalcet and Schizonepeta 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.

Schizonepeta safety at a glance

Schizonepeta overall Use caution Generally used in small amounts in traditional formulas, but high-quality safety data in humans are limited.
Pregnancy Avoid Safety in pregnancy has not been established, so it is best avoided.
Breastfeeding Avoid There is not enough information to consider it safe while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Cinacalcet

Interactions in our licensed database are recorded against drug classes, not just single drug names. Cinacalcet is filed under a single classification — oral drugs. Schizonepeta has documented interactions with 4 drug classes — the most serious being cytochrome p450 1a2 (cyp1a2) substrates (moderate), cytochrome p450 2d6 (cyp2d6) substrates (moderate) and cytochrome p450 2e1 (cyp2e1) substrates (moderate) — and none of Cinacalcet’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

No Interaction Found — But Data Suggests Schizonepeta and Cinacalcet 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.

  • Stomach upset / Vomiting / Nausea reported in 4.9% of FDA reports for Cinacalcet Additional detail

    “There is currently a limited amount of information available about the adverse effects of schizonepeta. Orally, a specific combination product (Zemaphyte, Phytopharm Plc) containing schizonepeta and numerous other ingredients has been reported to cause nausea, vomiting, colic, dyspepsia, dizziness, headache, and hair loss.”

Effects for Cinacalcet come from the ADVERSE REACTIONS section of its FDA label; effects for Schizonepeta come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 48,763 voluntary FDA FAERS reports for Cinacalcet 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.

How to take them

Some Cinacalcet Products Have a Food Rule — Schizonepeta Should Not Break It

At least one FDA label for a product containing Cinacalcet says to take it with food. If you take Schizonepeta on an empty stomach out of habit, keep them separate — and take Cinacalcet with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Cinacalcet products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Cinacalcet tablets should be taken with food or shortly after a meal ( 2.1 ) • Tablets should always be taken whole and not divided ( 2.1 ) • Secondary HPT in patients with CKD on dialysis ( 2.2 ): o Starting dose is 30 mg once daily.

From the Dosage and Administration section of the FDA label we read for Cinacalcet — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

See Every Supplement That Interacts With Cinacalcet

This page covers Schizonepeta only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Cinacalcet page lists 17 supplements it has a documented interaction with, worst first, each one explained.

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

By severity: 1 major · 7 moderate · 9 minor.

From our pharmacist’s overview on the Cinacalcet page

“Cinacalcet (Sensipar) is dosed carefully against blood calcium and parathyroid hormone levels, usually in people with kidney disease, so anything that changes how much of a dose actually gets absorbed deserves real attention. All 17 supplement interactions on file share a single mechanism.”

About Schizonepeta

What is Schizonepeta?

  • Common cold and early-stage fever
  • Itchy skin rashes and hives
  • Sore throat
  • Headache
  • Measles and other skin eruptions (traditional use)

Schizonepeta is a mint-family herb long used in traditional Chinese medicine, usually as part of combination formulas for colds, fevers, and itchy skin conditions. Modern human evidence is very limited, so its benefits are not well proven. Talk to a pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or taking other medicines.

Schizonepeta tenuifolia · Lamiaceae · Dried aerial parts (stems and flower spikes); sometimes the essential oil · Dried herb for decoctions (tea), powders, capsules, and as part of traditional herbal formulas

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

Schizonepeta: dosing

There is no well-established standardized dose for Schizonepeta. In traditional Chinese medicine it is typically used as a dried herb in a decoction, often combined with other herbs, and amounts are tailored by a trained practitioner.For commercial supplements, follow the directions on the product label.

About Cinacalcet

What Is Cinacalcet Used For?

Brand name: Sensipar

Cinacalcet tablets are used to treat secondary hyperparathyroidism (overactive parathyroid glands caused by kidney disease) in adult patients with chronic kidney disease (CKD) who are on dialysis. This use applies to cinacalcet tablets, cinacalcet hydrochloride tablets, and Sensipar. Importantly, cinacalcet is not approved for CKD patients who are not on dialysis, due to a higher risk of dangerously low calcium levels.

Cinacalcet tablets are also used to lower high calcium levels (hypercalcemia) in adults with parathyroid carcinoma (a rare cancer of the parathyroid gland), and in adults with primary hyperparathyroidism who need surgery based on their calcium levels but cannot have that surgery.

Most-Reported Side Effects for Cinacalcet

From FAERS, the FDA’s public side-effect reporting system (48,763 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Hospitalisation 6,957 reports
Laboratory test abnormal 4,226 reports
Nausea 2,405 reports

Taking Schizonepeta and Cinacalcet Together: Common Questions

Is it safe to take Schizonepeta with Cinacalcet?
We do not list a known interaction between Schizonepeta and Cinacalcet. 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 Schizonepeta and Cinacalcet have any of the same side effects?
Yes — our sources link each of them separately to 5 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.
Should I take Schizonepeta and Cinacalcet at the same time of day?
At least one FDA label for a product containing Cinacalcet says to take it with food. If you take Schizonepeta on an empty stomach out of habit, keep them separate and take Cinacalcet with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Cinacalcet products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Schizonepeta and Cinacalcet combination checked?
Interactions in our licensed database are recorded against drug classes. Cinacalcet is filed under 1 classification, and Schizonepeta has documented interactions with 4 drug classes — none of Cinacalcet's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Schizonepeta interact with any other medications?
Yes. Schizonepeta has 797 documented drug interactions in our database — Cinacalcet is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Cinacalcet interact with any supplements?
Yes. Cinacalcet has documented interactions with 17 supplements in our database — Schizonepeta is not one of them. The Cinacalcet interaction page linked on this page lists every one, ranked by severity.
