Drug & supplement interaction

Lentinan + Trilaciclib Dihydrochloride

Trilaciclib Dihydrochloride brand name: Cosela.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 27, 2026
The bottom line No known interaction

We found no known interaction between Lentinan and Trilaciclib Dihydrochloride 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.

Interaction report

Lentinan and Trilaciclib Dihydrochloride

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 Trilaciclib Dihydrochloride 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.

How we checked

Why No Interaction Is Listed for Trilaciclib Dihydrochloride

Interactions in our licensed database are recorded against drug classes, not just single drug names. Trilaciclib Dihydrochloride is filed under a single classification — qt interval-prolonging drugs. Lentinan has documented interactions with 8 drug classes — the most serious being cytochrome p450 1a2 (cyp1a2) substrates (moderate), cytochrome p450 2c19 (cyp2c19) substrates (moderate) and cytochrome p450 2d6 (cyp2d6) substrates (moderate) — and none of Trilaciclib Dihydrochloride’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 to actually watch for

No Interaction Found — But Data Suggests Lentinan and Trilaciclib Dihydrochloride May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

Overlapping uses

What Trilaciclib Dihydrochloride 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. Trilaciclib Dihydrochloride 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.

Trilaciclib Dihydrochloride is prescribed for: Trilaciclib Injection (brand name Cosela) is used in adults with extensive-stage small cell lung cancer. It helps decrease the incidence of chemotherapy-induced myelosuppression. That means it lowers the chance that chemotherapy will suppress the bone marrow's production of blood cells. It is given before certain chemotherapy regimens: a platinum/etoposide-containing regimen or a topotecan-containing regimen.

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 Trilaciclib Dihydrochloride 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.

From our pharmacist’s overview on the Trilaciclib Dihydrochloride page

“Trilaciclib (Cosela) is an infusion given before chemotherapy to shield bone marrow in people with small cell lung cancer, and its supplement list deserves genuine attention because all 13 flagged ingredients press on the same weak point, the heart's electrical rhythm. Each can lengthen the QT interval, the pause between beats on an EC…”

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 Trilaciclib Dihydrochloride Together: Common Questions

Is it safe to take Lentinan with Trilaciclib Dihydrochloride?
We do not list a known interaction between Lentinan and Trilaciclib Dihydrochloride. 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.
Do Lentinan and Trilaciclib Dihydrochloride have any of the same side effects?
Yes — our sources link each of them separately to 3 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Are Lentinan and Trilaciclib Dihydrochloride 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 Trilaciclib Dihydrochloride is being adjusted to a target.
How was the Lentinan and Trilaciclib Dihydrochloride combination checked?
Interactions in our licensed database are recorded against drug classes. Trilaciclib Dihydrochloride is filed under 1 classification, and Lentinan has documented interactions with 8 drug classes — none of Trilaciclib Dihydrochloride's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Lentinan interact with any other medications?
Yes. Lentinan has 814 documented drug interactions in our database — Trilaciclib Dihydrochloride is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Trilaciclib Dihydrochloride interact with any supplements?
Yes. Trilaciclib Dihydrochloride has documented interactions with 13 supplements in our database — Lentinan is not one of them. The Trilaciclib Dihydrochloride interaction page linked on this page lists every one, ranked by severity.
