The bottom line No known interaction

We found no known interaction between Squalamine and Pimecrolimus 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.

Squalamine and Pimecrolimus

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 Pimecrolimus 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 Pimecrolimus, 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

What Squalamine Itself Has Been Linked To

This is not an interaction — nothing below involves Pimecrolimus. It is the side-effect record for Squalamine on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Squalamine, this list is the first place to look. 2 entries are worth acting on rather than waiting out — marked below.

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

    “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.”

Everything above comes from the Natural Medicines adverse-effect record for Squalamine — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Pimecrolimus’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Pimecrolimus column appears here.

See Every Supplement That Interacts With Pimecrolimus

This page covers Squalamine only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Pimecrolimus page lists 3 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Dimethylsulfoxide (dmso) (moderate), Turpentine Oil (moderate) and Alchemilla (minor).

By severity: 2 moderate · 1 minor.

From our pharmacist’s overview on the Pimecrolimus page

“Pimecrolimus (Elidel) is an eczema cream, applied to the skin rather than swallowed, so its supplement interactions are few and they follow one pattern. All three ingredients on file are also used topically, and the two rated moderate, DMSO and turpentine oil, may pull more of the drug through the skin, amplifying both its benefit and…”

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.

What Is Pimecrolimus Topical Used For?

Brand name: Elidel

Pimecrolimus cream 1% is used to treat mild to moderate atopic dermatitis (eczema) in adults and children aged 2 and older. It is a second-line option — meaning it's tried when other topical prescription treatments haven't worked well enough, or when those treatments aren't a good fit.

It is intended for short-term and non-continuous use only, applied only to the affected areas. It is not approved for use in children under 2 years of age, and it should only be used in people with healthy immune systems.

Most-Reported Side Effects for Pimecrolimus
