Blue-green Algae and Lumateperone

Here is the interaction we found between these two, with the evidence behind it.

Moderate

IMMUNOSUPPRESSANTS

Why this applies to Lumateperone

Lumateperone falls under IMMUNOSUPPRESSANTS — the group Blue-green Algae interacts with.

Theoretically, concurrent use of blue-green algae might interfere with immunosuppressive therapy.
Blue-green algae have been shown to stimulate the immune system.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the honest take: the interaction we have on file is really about immunosuppressant medications, the kind used after a transplant or for autoimmune conditions. The idea is that blue-green algae may rev up the immune system, which could work against drugs meant to calm it down. Lumateperone (Caplyta) is not an immunosuppressant. It's an antipsychotic that works on brain chemistry to treat schizophrenia, so this particular immune-related concern doesn't really apply to it.

On top of that, this warning is only theoretical, based on lab and animal studies rather than people. I wouldn't expect blue-green algae to change how well your lumateperone works or cause its usual side effects (like drowsiness or dizziness). Still, since algae products can vary in quality, it's worth running it by your pharmacist or doctor first.

From our pharmacist’s overview on the Lumateperone page

“Lumateperone (Caplyta) treats schizophrenia and bipolar depression, and because the body clears it mainly through one liver enzyme, CYP3A4, this list deserves real care rather than a quick skim. The three ingredients rated major all hit that vulnerability or the drug itself: grapefruit can push lumateperone levels higher, St.”

About Blue-green Algae

What is Blue-green Algae?

Blue-green Algae
  • General nutrition and energy

Blue-green algae are nutrient-rich aquatic microorganisms (such as spirulina and Klamath Lake algae) taken as a supplement for energy, nutrition, and general wellness.

Talk to your pharmacist or doctor before using, especially during pregnancy or breastfeeding.

About Lumateperone

What Is Lumateperone Used For?

Brand name: Caplyta

Caplyta (lumateperone) is approved for adults with schizophrenia, depressive episodes associated with bipolar I or II disorder (bipolar depression), and as an add-on treatment for major depressive disorder (MDD).

For bipolar depression, Caplyta can be used on its own or alongside lithium or valproate. For MDD, Caplyta is used together with an antidepressant — not on its own as a standalone antidepressant.
