Canthaxanthin + Durvalumab
Durvalumab brand name: Imfinzi.
We found no known interaction between Canthaxanthin and Durvalumab 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. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.
Canthaxanthin and Durvalumab
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 Durvalumab and Canthaxanthin 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 Canthaxanthin at all — not against Durvalumab, 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 Durvalumab page
“Nearly everything on this page interacts with durvalumab (Imfinzi) for the same underlying reason, immune stimulation. Durvalumab is a cancer immunotherapy, and because the treatment works through the immune system itself, supplements that push immune activity in their own direction (echinacea, ashwagandha, astragalus, and dozens of si…”

- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions.
- Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Canthaxanthin reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Canthaxanthin and Durvalumab records this page draws on were last updated July 10, 2026.
- What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.
About Canthaxanthin
What is Canthaxanthin?
- Skin coloring or 'tanning pills'
- Food and feed coloring (e.g., to color farmed fish/poultry)
- Antioxidant supplement
- Erythropoietic protoporphyria (light sensitivity, historical/medical use)
Canthaxanthin is a reddish-orange carotenoid pigment used mainly as a coloring agent and in 'tanning pills.' There is little good evidence it provides health benefits, and high doses have been linked to a serious eye problem called canthaxanthin retinopathy, so the tanning-pill use is widely discouraged.
Carotenoid pigment (synthetic or from sources like the mushroom Cantharellus cinnabarinus, certain algae, and crustaceans) · Oral tablets and capsules, often marketed as 'tanning pills'; also used as a food coloring additive
An interaction check asks whether these two react with each other — it does not ask whether Canthaxanthin is a good idea for someone in your situation. Here is what our Canthaxanthin record says about it on its own.
Canthaxanthin: dosing
There is no established, recommended supplement dose of canthaxanthin for any health condition, and the high doses once used for skin coloring are not considered safe. Given the known risks at high doses, most people are better off avoiding supplemental canthaxanthin entirely.

What Is Durvalumab Injection Used For?
Brand name: Imfinzi
