Maidenhair Fern + Sodium Oxybate
Sodium Oxybate brand name: Xyrem.
We found no known interaction between Maidenhair Fern and Sodium Oxybate 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 Sodium Oxybate states a food rule worth keeping to.
Maidenhair Fern and Sodium Oxybate
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 Sodium Oxybate and Maidenhair 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 Maidenhair Fern at all — not against Sodium Oxybate, 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.

Some Sodium Oxybate Products Have a Food Rule — Maidenhair Fern Should Not Break It
At least one FDA label for a product containing Sodium Oxybate says to take it with food. If you take Maidenhair Fern on an empty stomach out of habit, keep them separate — and take Sodium Oxybate 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 Sodium Oxybate 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.
• Allow 2 hours after eating before dosing ( 2.3 ).

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.

See Every Supplement That Interacts With Sodium Oxybate
This page covers Maidenhair Fern only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Sodium Oxybate page lists 25 supplements it has a documented interaction with, worst first, each one explained.
The most serious there right now: Activated Charcoal (major), Biofeedback (moderate), Coffee Charcoal (moderate), Dendrobium (moderate) and European Mandrake (moderate).
By severity: 1 major · 15 moderate · 9 minor.
From our pharmacist’s overview on the Sodium Oxybate page
“Activated charcoal is the single major-rated interaction with sodium oxybate (Xyrem), and it earns that rating because the drug only works if each dose is fully absorbed; charcoal can bind it in the gut and weaken the nighttime control it provides for narcolepsy. Treat this list with genuine care, since 17 of the 25 ingredients on file…”

About Maidenhair Fern
What is Maidenhair Fern?
- Cough and respiratory complaints
- Hair and scalp health
- Cold and flu symptoms
- Mild urinary complaints
- Menstrual complaints
Maidenhair fern is a traditional herb used mainly in teas and syrups for coughs and respiratory complaints, but high-quality human studies are lacking. Because its safety has not been well studied, it is best to use it cautiously and to avoid it during pregnancy and breastfeeding.
Adiantum capillus-veneris · Pteridaceae · Fronds (leaves) and the whole above-ground plant · Tea (infusion), syrup, dried herb, liquid extract, and as an ingredient in traditional cough preparations
An interaction check asks whether these two react with each other — it does not ask whether Maidenhair Fern is a good idea for someone in your situation. Here is what our Maidenhair Fern record says about it on its own.
Maidenhair Fern: dosing
There is no standardized or well-established dose for maidenhair fern. Traditional use is mostly as a tea made from the dried fronds or as a syrup, but exact safe and effective amounts have not been confirmed by research.If you choose to use it, follow the directions on the product label and do not exceed the suggested amount. A pharmacist can help you decide whether it is appropriate for you and review it alongside your other medicines and supplements.

About Sodium Oxybate
What Is Sodium Oxybate Used For?
Brand name: Xyrem
Sodium oxybate treats two major symptoms of narcolepsy: cataplexy (sudden muscle weakness triggered by emotion) and excessive daytime sleepiness (EDS). It is available in several products, each approved for these uses.
Xyrem (oral solution) and the generic sodium oxybate oral solution are approved for cataplexy or EDS in patients with narcolepsy. Lumryz (extended-release oral suspension) is specifically approved for cataplexy or EDS in patients 7 years of age and older with narcolepsy. The generic sodium oxybate oral solution label does not include the pediatric indication due to marketing exclusivity held by Xyrem.
