Black Raspberry + Nivolumab, Relatlimab-rmbw
Nivolumab, Relatlimab-rmbw brand name: Opdualag.
We found no known interaction between Black Raspberry and Nivolumab, Relatlimab-rmbw 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.
Black Raspberry and Nivolumab, Relatlimab-rmbw
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 Nivolumab, Relatlimab-rmbw and Black Raspberry 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 Black Raspberry at all — not against Nivolumab, Relatlimab-rmbw, 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.

About Black Raspberry
What is Black Raspberry?
- Antioxidant support
- Heart health
- Oral and gum health
- Cancer prevention (under study)
- Inflammation
Black raspberry is a nutrient-rich fruit packed with antioxidants like anthocyanins and ellagic acid, and as a food it is generally safe and healthy. Some early research explores it for cancer prevention, oral health, and heart health, but the evidence is preliminary and far from proven. Enjoy it as part of a balanced diet, and talk to your pharmacist or doctor before using concentrated supplements.
Rubus occidentalis · Rosaceae · Fruit (berries); sometimes leaves and seeds · Fresh or frozen berries, juice, powder, capsules, extracts, lozenges, gels
An interaction check asks whether these two react with each other — it does not ask whether Black Raspberry is a good idea for someone in your situation. Here is what our Black Raspberry record says about it on its own.
