Drug & supplement interaction

Squalamine + Lenalidomide

Lenalidomide brand name: Revlimid.

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 Squalamine and Lenalidomide 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.

Squalamine and Lenalidomide

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 Lenalidomide 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 Lenalidomide, 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.

No Interaction Found — But Data Suggests Squalamine and Lenalidomide 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. One of them is worth acting on rather than waiting out — marked below.

Reported for Squalamine but not commonly for Lenalidomide: yellowing of the skin or eyes and vomiting.

Effects for Lenalidomide come from the ADVERSE REACTIONS section of its FDA label; effects for Squalamine come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 420,080 voluntary FDA FAERS reports for Lenalidomide 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.

From our pharmacist’s overview on the Lenalidomide page

“People taking lenalidomide (Revlimid) for multiple myeloma are often drawn to immune-boosting supplements, which is exactly why this list deserves genuine care. Fifty-three of its 70 entries are herbs and mushrooms thought to stimulate the immune system, astragalus, ginseng, and beta-glucans among them, and each could theoretically pus…”

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 Lenalidomide

What Is Lenalidomide Used For?

Brand name: Revlimid

Lenalidomide capsules (brand names Revlimid and Lenalidomide) are used to treat several blood cancers and related conditions in adults. These include multiple myeloma (MM) — both in combination with dexamethasone and as maintenance therapy after a stem cell transplant — and transfusion-dependent anemia caused by low- or intermediate-1-risk myelodysplastic syndromes (MDS) linked to a specific chromosome change called deletion 5q.

Lenalidomide capsules are also used for mantle cell lymphoma (MCL) that has come back or stopped responding after at least two prior treatments (one of which included bortezomib). In combination with a rituximab product, they treat previously treated follicular lymphoma (FL) and previously treated marginal zone lymphoma (MZL). Lenalidomide is not approved for chronic lymphocytic leukemia (CLL) outside of clinical trials.

Most-Reported Side Effects for Lenalidomide

From FAERS, the FDA’s public side-effect reporting system (420,080 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Diarrhea 31,469 reports
Fatigue 26,781 reports
Pneumonia 18,843 reports
Rash 18,228 reports
Plasma cell myeloma 17,121 reports

Taking Squalamine and Lenalidomide Together: Common Questions

Is it safe to take Squalamine with Lenalidomide?
We do not list a known interaction between Squalamine and Lenalidomide. 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 Lenalidomide 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.
Does Lenalidomide interact with any supplements?
Yes. Lenalidomide has documented interactions with 70 supplements in our database — Squalamine is not one of them. The Lenalidomide interaction page linked on this page lists every one, ranked by severity.
