Interaction report

Lentinan and Tremelimumab-actl

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 Tremelimumab-actl and Lentinan 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.

Lentinan safety at a glance

Lentinan overall Use caution Oral mushroom extracts are generally well tolerated, but the injectable medical form should only be used under a doctor's care.
Pregnancy Avoid There is not enough reliable safety information, so it is best to avoid use during pregnancy.
Breastfeeding Avoid Safety while breastfeeding is unknown, so avoiding it is the safer choice.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What to actually watch for

What Lentinan Itself Has Been Linked To

This is not an interaction — nothing below involves Tremelimumab-actl. It is the side-effect record for Lentinan on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Lentinan, this list is the first place to look. 2 entries are worth acting on rather than waiting out — marked below.

  • Chest pain Worth acting on Additional detail

    “Parenterally and orally, lentinan seems to be well tolerated. Orally, lentinan has been rarely reported to cause rash, diarrhea, and constipation. Parenterally, lentinan has been reported to cause gastrointestinal cramping, rash, myalgia, and fatigue. Mild thrombocytopenia has also been reported in clinical trials (6).”

Everything above comes from the Natural Medicines adverse-effect record for Lentinan — expand a row for the licensed statement it rests on.

Overlapping uses

What Tremelimumab-actl Is Prescribed For, and What Lentinan Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Tremelimumab-actl is a prescription medicine with approved uses on its FDA label. Lentinan is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Lentinan has been studied for:

  • Lung cancer studied, not established Lentinan has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Lentinan for lung cancer

    Meta-analyses of preliminary clinical research shows that lentinan injection increases the efficacy of chemotherapy in patients with lung cancer. In patients with non-small cell lung cancer, the objective response rate was improved by 31% over chemotherapy alone. However, lentinan did not improve the response to navelbine with cisplatin in a sub-group analysis.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Tremelimumab-actl on your own; if you are taking Lentinan for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Lentinan

What is Lentinan?

Lentinan
  • Immune support
  • Used alongside cancer treatment
  • Anti-inflammatory
  • General wellness/tonic
  • Antimicrobial support

Lentinan is a beta-glucan polysaccharide from shiitake mushrooms that is studied mainly as an immune-modulating add-on to cancer chemotherapy, where it is given by injection in a few countries. Evidence for oral supplements is limited, and quality varies widely between products. Talk with your pharmacist or doctor before using it, especially if you have a health condition or are pregnant or breastfeeding.

Lentinula edodes · Marasmiaceae · Fruiting body of the shiitake mushroom (the polysaccharide is extracted from it) · Injection (used in some countries under medical supervision), capsules, tablets, powdered mushroom extracts, oral liquid

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

Lentinan: dosing

There is no well-established standard dose for oral lentinan or shiitake supplements. Products differ a lot in how much actual beta-glucan they contain, so amounts on labels are not always comparable.If you choose to take an oral supplement, follow the directions on the product label and do not exceed them. The injectable medical form has its own dosing that is determined by a doctor as part of cancer treatment and is not something to manage at home.

Taking Lentinan and Tremelimumab-actl Together: Common Questions

Is it safe to take Lentinan with Tremelimumab-actl?
We do not list a known interaction between Lentinan and Tremelimumab-actl. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Are Lentinan and Tremelimumab-actl used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Lentinan in each. That is a conversation for your prescriber, especially if Tremelimumab-actl is being adjusted to a target.
Does Lentinan interact with any other medications?
Yes. Lentinan has 814 documented drug interactions in our database — Tremelimumab-actl is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
