Drug & supplement interaction

Astaxanthin + Octreotide

Octreotide brand names: Sandostatin, Mycapssa.

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 Astaxanthin and Octreotide 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 Octreotide 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.

Interaction report

Astaxanthin and Octreotide

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 Octreotide and Astaxanthin 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.

Astaxanthin safety at a glance

Astaxanthin overall Use caution Generally well tolerated in studies, but long-term safety data are limited.
Pregnancy Avoid Not enough safety data, so it is best to avoid during pregnancy.
Breastfeeding Avoid Not enough safety data, so it is best to avoid while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Octreotide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Octreotide is filed under 2 classifications — cytochrome p450 3a4 (cyp3a4) inhibitors, oral drugs. Astaxanthin has documented interactions with 2 drug classes — the most serious being cytochrome p450 2b6 (cyp2b6) substrates (moderate) and cytochrome p450 3a4 (cyp3a4) substrates (moderate) — and none of Octreotide’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

No Interaction Found — But Data Suggests Astaxanthin and Octreotide 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.

  • Stomach pain / Diarrhea Additional detail

    Astaxanthin

    “Orally, astaxanthin 6 mg daily has caused two cases of increased bowel movements and two cases of red fecal color. A higher dose of astaxanthin (AstaCarox, AstaReal AB) 40 mg daily has caused severe stomach/abdominal pain in two patients.”

Effects for Octreotide come from the ADVERSE REACTIONS section of its FDA label; effects for Astaxanthin come from the Natural Medicines adverse-effect record, quoted above. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

How to take them

Some Octreotide Products Have a Food Rule — Astaxanthin Should Not Break It

At least one FDA label for a product containing Octreotide says to take it on an empty stomach. Most supplements — Astaxanthin included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Octreotide on its own and move Astaxanthin 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 Octreotide 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 DOSAGE AND ADMINISTRATION Take MYCAPSSA orally with a glass of water on an empty stomach, at least 1 hour before a meal or at least 2 hours after a meal (‎ 2.1 ).

From the Dosage and Administration section of the FDA label we read for Octreotide — 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 Octreotide page

“Take this page with genuine care if you use octreotide (Sandostatin injections or Mycapssa capsules) for acromegaly or hormone-secreting tumors, since steady drug levels are what keep symptoms suppressed. Of the 30 ingredients on file, one rates major, activated charcoal, which can pull octreotide out of circulation and blunt its effec…”

About Astaxanthin

What is Astaxanthin?

Astaxanthin
  • Antioxidant support
  • Skin health and aging
  • Eye health
  • Exercise recovery
  • Heart and inflammation support

Astaxanthin is a reddish carotenoid pigment with strong antioxidant activity in the lab, and it is widely promoted for skin, eye, heart, and exercise benefits. Early human studies are promising for a few uses, but the overall evidence is still limited and not strong enough to make firm claims. It appears generally well tolerated at typical supplement doses, but talk with your pharmacist or doctor before starting it.

Pigment extracted from microalgae (mainly Haematococcus pluvialis), yeast, and some seafood · Capsules, soft gels, tablets, and as an ingredient in some skin creams

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

Astaxanthin: dosing

There is no official standardized dose for astaxanthin, and amounts used in studies have varied. Because of this, the best approach is to follow the directions on the product label.Astaxanthin is fat-soluble, so it is often taken with a meal that contains some fat to help absorption.

About Octreotide

What Is Octreotide Used For?

Brand names: Sandostatin, Mycapssa

Octreotide injection (available as Sandostatin, BYNFEZIA Pen, and other octreotide acetate injection products) is used to lower abnormally high growth hormone and IGF-1 levels in acromegaly, and to reduce the severe diarrhea and flushing associated with metastatic carcinoid tumors and the profuse watery diarrhea caused by VIPomas (vasoactive intestinal peptide-secreting tumors).

Mycapssa, the oral delayed-release capsule, is approved specifically for long-term maintenance treatment of acromegaly in patients who have already responded to and tolerated treatment with octreotide or lanreotide injections. It is not indicated for carcinoid tumors or VIPomas.

Taking Astaxanthin and Octreotide Together: Common Questions

Is it safe to take Astaxanthin with Octreotide?
We do not list a known interaction between Astaxanthin and Octreotide. 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 Astaxanthin and Octreotide have any of the same side effects?
Yes — our sources link each of them separately to 2 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 Astaxanthin and Octreotide at the same time of day?
At least one FDA label for a product containing Octreotide 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 Octreotide on its own and move Astaxanthin 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 Astaxanthin and Octreotide combination checked?
Interactions in our licensed database are recorded against drug classes. Octreotide is filed under 2 classifications, and Astaxanthin has documented interactions with 2 drug classes — none of Octreotide'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 Astaxanthin interact with any other medications?
Yes. Astaxanthin has 671 documented drug interactions in our database — Octreotide 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 Octreotide interact with any supplements?
Yes. Octreotide has documented interactions with 30 supplements in our database — Astaxanthin is not one of them. The Octreotide interaction page linked on this page lists every one, ranked by severity.
