Here is the interaction we found between these two, with the evidence behind it.
MONOAMINE OXIDASE INHIBITORS (MAOIs)
Why this applies to Ozanimod Hydrochloride
Ozanimod Hydrochloride falls under MONOAMINE OXIDASE INHIBITORS (MAOIs) — the group Cereus interacts with.
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.
Here's the connection worth knowing about. Ozanimod (Zeposia) has a mild MAO-inhibiting effect, which means it slows down how your body breaks down certain compounds, including a substance called tyramine. Night-blooming cereus is grouped with MAOIs here because, in theory, large supplement doses could add some tyramine to the mix.
When tyramine builds up alongside an MAOI like ozanimod, the real-world worry is a sudden spike in blood pressure, which can show up as a pounding headache, flushing, or a racing heart. I want to be honest though: this interaction is theoretical, based on pharmacology rather than reported cases, and it would mainly apply to concentrated, excessive cereus doses, not trace amounts. Still, since ozanimod already comes with tyramine cautions, please run any cereus use past your pharmacist or doctor first.

About Cereus
What is Cereus?
- Heart palpitations
- Mild heart symptoms
- Anxiety and nervous tension
- Shortness of breath
- Fluid retention
Cereus (often called night-blooming cereus) is a cactus traditionally used in folk and homeopathic medicine for heart-related complaints like palpitations. High-quality human evidence supporting these uses is lacking, and because it may affect the heart, it should be used only under medical guidance. Pregnant and breastfeeding people should avoid it.
