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 Ixazomib Citrate states a food rule worth keeping to.

Ascophyllum Nodosum and Ixazomib Citrate

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 Ixazomib Citrate and Ascophyllum Nodosum 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.

Ascophyllum Nodosum safety at a glance

Ascophyllum Nodosu... overall Use caution Generally used in foods, but its iodine content and possible heavy metal contamination warrant caution.
Pregnancy Avoid Avoid due to high iodine levels and possible contaminants that may affect the baby.
Breastfeeding Avoid Avoid because iodine and contaminants can pass into breast milk.

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

How we checked

Why No Interaction Is Listed for Ixazomib Citrate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ixazomib Citrate is filed under 3 classifications — hepatotoxic drugs, cytochrome p450 3a4 (cyp3a4) substrates, oral drugs. Ascophyllum Nodosum has documented interactions with 3 drug classes — the most serious being amiodarone (cordarone) (moderate), antithyroid drugs (moderate) and thyroid hormone (moderate) — and none of Ixazomib Citrate’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

What Ixazomib Citrate’s Own FDA Label Lists

This is not an interaction — none of it involves Ascophyllum Nodosum. These are the most notable effects listed in the ADVERSE REACTIONS section of Ixazomib Citrate’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. 3 of them are worth acting on rather than waiting out — marked below.

  • A low platelet count Worth acting on
  • A low white blood cell count Worth acting on
  • Liver problems Worth acting on
  • Numbness or tingling
  • Constipation
  • Swelling
  • Diarrhea
  • A skin rash
  • Vomiting
  • Nausea

From the ADVERSE REACTIONS section of the FDA label for Ixazomib Citrate. Read the label on DailyMed › Ascophyllum Nodosum’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Ascophyllum Nodosum side to compare — that is a limit of the record, not a statement that Ascophyllum Nodosum has no side effects.

How to take them

Some Ixazomib Citrate Products Have a Food Rule — Ascophyllum Nodosum Should Not Break It

At least one FDA label for a product containing Ixazomib Citrate says to take it on an empty stomach. Most supplements — Ascophyllum Nodosum included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Ixazomib Citrate on its own and move Ascophyllum Nodosum to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Ixazomib Citrate 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.

( 2.1 ) Dose should be taken at least one hour before or at least two hours after food.

From the Dosage and Administration section of the FDA label we read for Ixazomib Citrate — 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.

From our pharmacist’s overview on the Ixazomib Citrate page

“Anyone taking ixazomib citrate (Ninlaro) for multiple myeloma should give this list real weight, because a supplement that shifts this chemotherapy's blood level can shift how well it works against the cancer. Of the 168 ingredients on file, 121 act on CYP3A4, the enzyme that clears ixazomib.”

About Ascophyllum Nodosum

What is Ascophyllum Nodosum?

Ascophyllum Nodosum
  • Weight management
  • Blood sugar support
  • Thyroid support (iodine source)
  • Digestive health
  • Source of vitamins and minerals
  • Joint comfort

Ascophyllum nodosum (often sold as bladderwrack or brown seaweed) is a nutrient-rich algae that people use for weight, blood sugar, and thyroid support, but solid human evidence is limited for most of these uses. Because it naturally contains iodine and can absorb heavy metals like arsenic, it should be used cautiously, and pregnant or breastfeeding people should avoid it unless a doctor approves.

Ascophyllum nodosum · Fucaceae · Whole seaweed (thallus/fronds) · Capsules, tablets, powder, extracts, teas, and topical products

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

Ascophyllum Nodosum: dosing

There is no well-established standard dose of Ascophyllum nodosum. Products vary widely in strength and iodine content, which makes consistent dosing difficult.If you choose to use it, follow the directions on the product label and do not exceed the recommended amount.

About Ixazomib

What Is Ixazomib Used For?

Brand name: Ninlaro

Ninlaro (ixazomib) is used to treat multiple myeloma — a cancer of plasma cells in the bone marrow. It is not used alone; it is always taken together with two other medicines, lenalidomide and dexamethasone. This combination is for adults who have already received at least one prior treatment for their myeloma.

Ninlaro is not recommended for use as maintenance therapy or in newly diagnosed multiple myeloma patients on a lenalidomide and dexamethasone regimen outside of controlled clinical trials.

Taking Ascophyllum Nodosum and Ixazomib Citrate Together: Common Questions

Is it safe to take Ascophyllum Nodosum with Ixazomib Citrate?
We do not list a known interaction between Ascophyllum Nodosum and Ixazomib Citrate. 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.
Should I take Ascophyllum Nodosum and Ixazomib Citrate at the same time of day?
At least one FDA label for a product containing Ixazomib Citrate says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Ixazomib Citrate on its own and move Ascophyllum Nodosum to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
How was the Ascophyllum Nodosum and Ixazomib Citrate combination checked?
Interactions in our licensed database are recorded against drug classes. Ixazomib Citrate is filed under 3 classifications, and Ascophyllum Nodosum has documented interactions with 3 drug classes — none of Ixazomib Citrate'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 Ascophyllum Nodosum interact with any other medications?
Yes. Ascophyllum Nodosum has 22 documented drug interactions in our database — Ixazomib Citrate 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 Ixazomib Citrate interact with any supplements?
Yes. Ixazomib Citrate has documented interactions with 168 supplements in our database — Ascophyllum Nodosum is not one of them. The Ixazomib Citrate interaction page linked on this page lists every one, ranked by severity.
