Black Hoof Mushroom and Lomustine

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 Lomustine and Black Hoof Mushroom 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.

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.

How we checked

Why No Interaction Is Listed for Lomustine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Lomustine is filed under 3 classifications — alkylating agents, antineoplastics, oral drugs. Black Hoof Mushroom has documented interactions with 3 drug classes — the most serious being cytochrome p450 1a2 (cyp1a2) substrates (moderate), cytochrome p450 2e1 (cyp2e1) substrates (moderate) and immunosuppressants (moderate) — and none of Lomustine’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What Lomustine’s Own FDA Label Lists

This is not an interaction — none of it involves Black Hoof Mushroom. These are the most notable effects listed in the ADVERSE REACTIONS section of Lomustine’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 5 of them are worth acting on rather than waiting out — marked below.

  • Loss of vision Worth acting on
  • Unsteadiness Worth acting on
  • Confusion Worth acting on
  • Kidney problems Worth acting on
  • Liver problems Worth acting on
  • Mouth irritation or sores
  • Hair loss
  • Blurred vision
  • Tiredness mentioned in 8.3% of FDA reports for Lomustine

Showing the 10 most notable of 11 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Lomustine. Read the label on DailyMed › Where a percentage is shown, it is the share of 2,533 voluntary FDA FAERS reports for Lomustine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Black Hoof Mushroom’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Black Hoof Mushroom side to compare — that is a limit of the record, not a statement that Black Hoof Mushroom has no side effects.

Everything else you take

By severity: 1 major · 14 moderate · 10 minor.

From our pharmacist’s overview on the Lomustine page

“One capsule of lomustine (Ceenu) often carries a whole chemotherapy cycle, so supplements that keep it from being absorbed, or that blunt its cancer-fighting action, deserve more respect here than with most drugs. The lone major-rated interaction, activated charcoal, can bind lomustine in the gut and sharply cut how much reaches the body.”

About Black Hoof Mushroom

What is Black Hoof Mushroom?

Black Hoof Mushroom
  • Immune system support
  • Antioxidant support
  • General wellness
  • Traditional cancer-supportive use
  • Inflammation

Black Hoof Mushroom (Phellinus linteus) is a medicinal mushroom long used in East Asian traditional medicine, mainly for immune support. Most of the supporting evidence comes from laboratory and animal studies, and high-quality human research is limited. Talk to your pharmacist or doctor before using it, especially if you have a health condition or take other medicines.

Phellinus linteus · Hymenochaetaceae · Fruiting body (the woody mushroom that grows on tree trunks) · Capsules, tablets, powdered extracts, teas, and tinctures

An interaction check asks whether these two react with each other — it does not ask whether Black Hoof Mushroom is a good idea for someone in your situation. Here is what our Black Hoof Mushroom record says about it on its own.

Black Hoof Mushroom: dosing
