Ipriflavone and Mirikizumab-mrkz

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

Moderate

IMMUNOSUPPRESSANTS

Why this applies to Mirikizumab-mrkz

Mirikizumab-mrkz falls under IMMUNOSUPPRESSANTS — the group Ipriflavone interacts with.

Concurrent use of ipriflavone and immunosuppressant drugs might have additive effects on inhibiting immune function. Some patients taking ipriflavone experience subclinical lymphocytopenia; avoid concurrent use. Immunosuppressant drugs include azathioprine (Imuran), basiliximab (Simulect), cyclosporine (Neoral, Sandimmune), daclizumab (Zenapax), muromonab-CD3 (OKT3, Orthoclone OKT3), mycophenolate (CellCept), tacrolimus (FK506, Prograf), sirolimus (Rapamune), prednisone (Deltasone, Orasone), and other corticosteroids (glucocorticoids).
Severity Moderate Likelihood Possible Evidence A

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 explains PharmD, Clinical Pharmacist

Here's the thing to know about pairing ipriflavone with Omvoh (mirikizumab). Omvoh is a biologic antibody that calms an overactive immune system to treat ulcerative colitis and Crohn's disease. It already dials down part of your immune response. Ipriflavone, in some people, can quietly lower white blood cell counts (a mild drop called lymphocytopenia). Stack the two and you may be pushing immune activity down a little further than intended.

In real terms, that could mean a slightly higher chance of infections, which is already something folks on Omvoh watch for. This isn't about Omvoh building up in your body; it's about the two working in the same downward direction. Ipriflavone hasn't proven itself for bone health anyway, so before combining them, please check with your pharmacist or doctor.

About Ipriflavone

What is Ipriflavone?

Ipriflavone
  • Bone density and osteoporosis
  • Postmenopausal bone loss
  • Athletic performance
  • Tinnitus related to bone disorders

Ipriflavone is a synthetic isoflavone studied mainly for bone health and osteoporosis, but high-quality research has not shown that it reliably prevents fractures or builds strong bone. Because it can lower white blood cell counts in some people and its long-term safety is not well established, talk with your pharmacist or doctor before using it.

About Mirikizumab-Mrkz

What Is Mirikizumab-Mrkz Used For?

Brand name: Omvoh

Omvoh (mirikizumab-mrkz) is used to treat moderately to severely active ulcerative colitis in adults — a condition where the large intestine becomes chronically inflamed and ulcerated. It is also used to treat moderately to severely active Crohn's disease in adults, another form of inflammatory bowel disease that can affect any part of the digestive tract.

Both uses are specific to Omvoh administered by injection — first as intravenous (into the vein) infusions to start treatment, then as subcutaneous (under the skin) injections for ongoing maintenance.
