Sarsaparilla + Carfilzomib
Carfilzomib brand name: Kyprolis.
We found no known interaction between Sarsaparilla and Carfilzomib 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.
Sarsaparilla and Carfilzomib
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 Carfilzomib and Sarsaparilla 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.
Sarsaparilla safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Carfilzomib
Interactions in our licensed database are recorded against drug classes, not just single drug names. Carfilzomib is filed under a single classification — hepatotoxic drugs. Sarsaparilla has documented interactions with 2 drug classes — the most serious being digoxin (lanoxin) (moderate) and lithium (moderate) — and none of Carfilzomib’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.
Sarsaparilla Does Interact With Other Medications
Sarsaparilla has 2 moderate known drug interactions in our database — Carfilzomib isn’t one of them. If you take anything else, check it against the full list below.

What Carfilzomib Is Prescribed For, and What Sarsaparilla Has Been Studied For
These two come up together because they touch the same health topic — not because they do the same job. Carfilzomib is a prescription medicine with approved uses on its FDA label. Sarsaparilla is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.
Carfilzomib is prescribed for: Kyprolis (carfilzomib) injection is used to treat adults with relapsed or refractory multiple myeloma — a cancer of plasma cells in the bone marrow — whose disease has come back or stopped responding to earlier treatment. It is approved for patients who have received one or more prior lines of therapy. Kyprolis may be given alone or in combination with other medications, including lenalidomide and dexamethasone, dexamethasone alone, daratumumab and dexamethasone, daratumumab and hyaluronidase-fihj and dexamethasone, or isatuximab and dexamethasone. The specific combination depends on how many prior treatments a patient has received and what their care team recommends.

-
Cancer studied, not established Sarsaparilla has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows
Sarsaparilla for cancer
Although there has been interest in using oral sarsaparilla for cancer, there is insufficient reliable information about the clinical effects of sarsaparilla for this purpose.
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 Carfilzomib on your own; if you are taking Sarsaparilla for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.
See Every Supplement That Interacts With Carfilzomib
This page covers Sarsaparilla only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Carfilzomib page lists 38 supplements it has a documented interaction with, worst first, each one explained.
The most serious there right now: Beer (major), Siberian Cocklebur (major), Wine (major), Ashwagandha (moderate) and Black Cohosh (moderate).
By severity: 3 major · 35 moderate.
From our pharmacist’s overview on the Carfilzomib page
“Every supplement on this page shares a single concern with carfilzomib (Kyprolis): extra strain on the liver. Carfilzomib is an IV chemotherapy for multiple myeloma, and that treatment is demanding enough without an herb quietly injuring the organ that has to keep pace.”

About Sarsaparilla
What is Sarsaparilla?
- Skin conditions like psoriasis
- Joint pain and arthritis
- General tonic or 'blood purifier'
- Boosting athletic performance
- Flavoring in beverages
Sarsaparilla is a traditional root used in teas, tonics, and old-fashioned root beer flavoring. Modern evidence for its health claims is very limited and comes mostly from lab studies, so it should not replace proven treatments. It is generally considered low-risk for short-term use, but pregnant and breastfeeding people should avoid it due to a lack of safety data.
Smilax spp. · Smilacaceae · Dried root and rhizome · Capsules, tablets, dried root, tea, liquid extract, tincture
An interaction check asks whether these two react with each other — it does not ask whether Sarsaparilla is a good idea for someone in your situation. Here is what our Sarsaparilla record says about it on its own.
Sarsaparilla: dosing
There is no well-established standard dose for sarsaparilla. Products vary widely in strength and how they are prepared, so the amount in one capsule or tea may be very different from another.The safest approach is to follow the directions on the product label and not exceed the recommended amount.
