Iceland Moss + Enzalutamide
Enzalutamide brand name: Xtandi.
We found no known interaction between Iceland Moss and Enzalutamide 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.
Iceland Moss and Enzalutamide
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 Enzalutamide and Iceland Moss 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 Iceland Moss at all — not against Enzalutamide, 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 Iceland Moss
What is Iceland Moss?
- Dry cough and throat irritation
- Sore or inflamed throat and mouth
- Digestive upset and loss of appetite
- Bronchial irritation
- Soothing mucous membranes
Iceland moss is a lichen traditionally used as a soothing remedy for dry cough and throat or mouth irritation, mainly because of its mucilage (gel-forming fibers). High-quality human studies are limited, so its benefits are not well proven. It is generally considered well tolerated for short-term use, but pregnant and breastfeeding people should avoid it due to a lack of safety data.
Cetraria islandica · Parmeliaceae · Whole lichen (thallus) · Tea, lozenges, liquid extracts, tinctures, capsules, syrups
An interaction check asks whether these two react with each other — it does not ask whether Iceland Moss is a good idea for someone in your situation. Here is what our Iceland Moss record says about it on its own.
Iceland Moss: dosing
There is no official, standardized dose of Iceland moss. Traditional preparations include a tea made from the dried lichen, lozenges, and liquid extracts, and the right amount depends on the specific product.The safest approach is to follow the directions on the product label and not exceed the recommended amount.

About Enzalutamide
What Is Enzalutamide Used For?
Brand name: Xtandi
Xtandi (enzalutamide) is used to treat prostate cancer in three specific situations: castration-resistant prostate cancer (CRPC), metastatic castration-sensitive prostate cancer (mCSPC), and non-metastatic castration-sensitive prostate cancer with biochemical recurrence at high risk for metastasis (high-risk BCR).
Castration-resistant means the cancer has continued to grow despite low testosterone levels. Castration-sensitive means the cancer still responds to testosterone-lowering therapy. In most of these cases, Xtandi is used alongside a GnRH analog (a hormone-lowering injection) or after surgical removal of the testicles — except in the high-risk BCR setting, where it may be used with or without a GnRH analog.
Most-Reported Side Effects for Enzalutamide
From FAERS, the FDA’s public side-effect reporting system (58,437 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
