Drug & supplement interaction

Squalamine + Eltrombopag

Eltrombopag brand names: Promacta, Revolade, Alvaiz.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Squalamine and Eltrombopag 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 Eltrombopag 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.

Squalamine and Eltrombopag

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 Eltrombopag and Squalamine 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 Squalamine at all — not against Eltrombopag, 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.

Squalamine safety at a glance

Squalamine overall Not established Squalamine has mainly been studied in research settings, and its safety as a self-care supplement is not established.
Pregnancy Avoid There is not enough safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid Safety while breastfeeding is unknown, so avoid using it.

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

What to actually watch for

No Interaction Found — But Data Suggests Squalamine and Eltrombopag 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. 2 of them are worth acting on rather than waiting out — marked below.

  • Yellowing of the skin or eyes Worth acting on Additional detail

    Squalamine

    “Intravenously, squalamine at doses above 192 mg/m2 daily has been associated with reports of elevated hepatic transaminase levels. Levels of aspartate aminotransferase and alanine aminotransferase were about 5 to over 20 times above upper normal levels in some patients. The increased levels were noted 2-5 days after beginning squalamine. Both values returned to baseline within 6-23 days.”

How to take them

Some Eltrombopag Products Have a Food Rule — Squalamine Should Not Break It

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

Do not split, chew, or crush tablets and mix with food or liquids.

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

Everything else you take

See Every Supplement That Interacts With Eltrombopag

This page covers Squalamine only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Eltrombopag page lists 55 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Beer (major), Siberian Cocklebur (major), Wine (major) and Ashwagandha (moderate).

By severity: 4 major · 42 moderate · 9 minor.

From our pharmacist’s overview on the Eltrombopag page

“Eltrombopag (Promacta, Revolade) boosts platelet production, and because the drug itself can stress the liver, this list warrants genuine care. Thirty-eight of the 55 supplements and herbs here can injure the liver on their own, so combining them stacks risk on an organ your doctor is already watching with blood tests.”

About Squalamine

What is Squalamine?

  • Cancer (investigational)
  • Age-related macular degeneration (eye disease)
  • Antimicrobial / antiviral interest
  • Anti-angiogenesis (blocking new blood vessel growth)

Squalamine is a compound first found in the dogfish shark that has mainly been studied as an experimental drug, not as a common dietary supplement. Research has looked at it for cancer and certain eye diseases, but evidence in people is limited and it is not an approved or widely available treatment. Talk to your doctor or pharmacist before using any product claiming to contain it.

Originally isolated from the liver and tissues of the dogfish shark (Squalus acanthias); also made synthetically · Investigational drug forms (intravenous infusion, eye drops); not a typical over-the-counter dietary supplement

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

Squalamine: dosing

There is no established or standardized dose of squalamine for use as a dietary supplement. Keep in mind that supplement quality and labeling are not always reliable, and a pharmacist can help you decide whether using such a product makes sense for you.

About Eltrombopag

What Is Eltrombopag Used For?

Brand names: Promacta, Revolade, Alvaiz

Eltrombopag treats thrombocytopenia (low platelet counts) in several different conditions. It is used for adults and children (age 1 and older, depending on the product) with persistent or chronic immune thrombocytopenia (ITP) — a condition where the immune system destroys platelets — when other treatments like steroids or immunoglobulins haven't worked well enough. It is also used to raise platelet counts in adults with chronic hepatitis C whose low platelet count prevents them from starting or staying on interferon-based antiviral therapy.

Eltrombopag tablets (including Promacta) are also approved — alone or combined with immunosuppressive therapy — for adults and certain children (age 2 and older) with severe aplastic anemia, a serious bone marrow failure condition. Alvaiz (a specific brand) shares most of these uses but has product-specific dosing that is not interchangeable milligram-for-milligram with other eltrombopag products. The oral suspension formulation is approved for ITP and for refractory severe aplastic anemia, but is not approved for first-line severe aplastic anemia in combination with immunosuppressive therapy.

Taking Squalamine and Eltrombopag Together: Common Questions

Is it safe to take Squalamine with Eltrombopag?
We do not list a known interaction between Squalamine and Eltrombopag. 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 Squalamine and Eltrombopag have any of the same side effects?
Yes — our sources link each of them separately to 7 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 Squalamine and Eltrombopag at the same time of day?
At least one FDA label for a product containing Eltrombopag says to take it with food. If you take Squalamine on an empty stomach out of habit, keep them separate and take Eltrombopag with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Eltrombopag products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Does Eltrombopag interact with any supplements?
Yes. Eltrombopag has documented interactions with 55 supplements in our database — Squalamine is not one of them. The Eltrombopag interaction page linked on this page lists every one, ranked by severity.
