The bottom line No known interaction

We found no known interaction between Squalamine and Talbutal 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 Talbutal

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 Talbutal 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 Talbutal, 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 Talbutal. 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 haven’t matched Talbutal to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Talbutal.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

From our pharmacist’s overview on the Talbutal page

“Every one of the 17 supplements that interacts with Talbutal (Lotusate) works through your gut, changing how much of this barbiturate sleep aid actually reaches your bloodstream. That deserves genuine caution, because barbiturates leave little room for error.”

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.

From our Squalamine monograph — the full record covers uses, side effects and every documented interaction.
