Lungmoss + Glecaprevir, Pibrentasvir
Glecaprevir, Pibrentasvir brand name: Mavyret.
We found no known interaction between Lungmoss and Glecaprevir, Pibrentasvir 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 label for Glecaprevir, Pibrentasvir states a food rule worth keeping to.
Lungmoss and Glecaprevir, Pibrentasvir
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 Glecaprevir, Pibrentasvir and Lungmoss 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 Lungmoss at all — not against Glecaprevir, Pibrentasvir, 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.
Lungmoss safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Some Glecaprevir, Pibrentasvir Products Have a Food Rule — Lungmoss Should Not Break It
At least one FDA label for a product containing Glecaprevir, Pibrentasvir says to take it with food. If you take Lungmoss on an empty stomach out of habit, keep them separate — and take Glecaprevir, Pibrentasvir with a meal where the label says to.
This may not be true of your version. Food instructions belong to the product, not the ingredient: two Glecaprevir, Pibrentasvir products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.
Recommended dosage in adults: Three tablets taken at the same time orally once daily (total daily dose: glecaprevir 300 mg and pibrentasvir 120 mg) with food.

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

From our pharmacist’s overview on the Glecaprevir, Pibrentasvir page
“Mavyret (glecaprevir and pibrentasvir) is a short course of pills meant to cure hepatitis C, so I read its supplement list with real caution. Nearly everything on it can shift how much of the drug reaches your blood, mostly through the CYP3A4 enzyme or the P-glycoprotein transporter that handles it.”

Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Lungmoss is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
- Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Lungmoss reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Lungmoss and Glecaprevir, Pibrentasvir records this page draws on were last updated July 11, 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 Lungmoss
What is Lungmoss?
- Coughs and respiratory complaints
- Sore throat
- Loss of appetite
- Digestive upset
- Wound and skin care (traditional, topical)
Lungmoss (Lobaria pulmonaria) is a forest lichen used in traditional folk medicine mostly for coughs and respiratory problems. There is very little modern human research to support these uses, and its safety has not been well studied, so it should be used with caution and only after talking with a pharmacist or doctor.
Lobaria pulmonaria · Lobariaceae · Whole lichen (thallus) · Tea, tincture, dried lichen, occasionally in syrups or topical preparations
An interaction check asks whether these two react with each other — it does not ask whether Lungmoss is a good idea for someone in your situation. Here is what our Lungmoss record says about it on its own.
Lungmoss: dosing
There is no established or standardized dose for lungmoss. Traditional uses involved brewing the dried lichen into a tea or making a tincture, but reliable, science-based dosing guidelines do not exist.If you choose to use a commercial product, follow the directions on the label and do not exceed the recommended amount.
