Arrowroot + Mirikizumab-mrkz
Mirikizumab-mrkz brand name: Omvoh.
We found no known interaction between Arrowroot and Mirikizumab-mrkz 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.
Arrowroot and Mirikizumab-mrkz
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 Mirikizumab-mrkz and Arrowroot 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 Arrowroot at all — not against Mirikizumab-mrkz, 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.

From our pharmacist’s overview on the Mirikizumab-mrkz page
“Mirikizumab (Omvoh) treats inflammatory bowel disease by dialing down part of the immune system, and its interaction list deserves genuine wariness, most of all around the liver. The three most serious entries, Siberian cocklebur plus beer and wine, all raise the odds of liver damage when combined with a medication that can stress the…”

About Arrowroot
What is Arrowroot?
- Diarrhea
- Irritable bowel syndrome (IBS) symptoms
- Digestive upset
- Gluten-free thickener/food ingredient
- Soothing skin and cosmetics
Arrowroot is a starch made from the roots of Maranta arundinacea and is mainly used as a gentle, easy-to-digest thickening agent in food. Some people use it for diarrhea and digestive discomfort, but solid human evidence for these health benefits is limited. As a food it is generally well tolerated, but talk with your pharmacist or doctor before using it to treat a medical condition.
