Lady Fern + Megestrol Acetate
Megestrol Acetate brand names: Megestrol, Megace.
We found no known interaction between Lady Fern and Megestrol Acetate 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.
Lady Fern and Megestrol Acetate
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 Megestrol Acetate and Lady Fern 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 Lady Fern at all — not against Megestrol Acetate, 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.

From our pharmacist’s overview on the Megestrol Acetate page
“Megestrol acetate (Megace) is usually prescribed to restore appetite and weight in people who are seriously ill, so the drug only helps if it actually gets absorbed. That is exactly where this list earns real caution.”

Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Lady Fern 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 Lady Fern reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 27, 2026. The Lady Fern and Megestrol Acetate records this page draws on were last updated June 20, 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 Lady Fern
What is Lady Fern?
- Traditional digestive complaints
- Folk remedy for intestinal worms
- Topical use for wounds and skin irritation
- General traditional tonic
- Eaten as a foraged spring vegetable (fiddleheads)
Lady fern is a woodland fern used in some folk traditions and occasionally foraged for its young fronds (fiddleheads). There is very little scientific evidence to support any medicinal use, and some ferns can be unsafe if raw or improperly prepared, so caution is warranted.
Athyrium filix-femina · Athyriaceae · Rhizome (rootstock) and young fronds (fiddleheads) · Dried rhizome, traditional decoction, occasionally cooked young fronds (fiddleheads) as food
An interaction check asks whether these two react with each other — it does not ask whether Lady Fern is a good idea for someone in your situation. Here is what our Lady Fern record says about it on its own.
