Dimethylglycine (dmg) + Perampanel
Perampanel brand name: Fycompa.
We found no known interaction between Dimethylglycine (dmg) and Perampanel 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.
Dimethylglycine (dmg) and Perampanel
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 Perampanel and Dimethylglycine (dmg) 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 Dimethylglycine (dmg) at all — not against Perampanel, 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.

What Perampanel Is Prescribed For, and What Dimethylglycine (dmg) Has Been Studied For
These two come up together because they touch the same health topic — not because they do the same job. Perampanel is a prescription medicine with approved uses on its FDA label. Dimethylglycine (dmg) is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.
Perampanel is prescribed for: Perampanel — available as Fycompa and in generic forms — is used to treat partial-onset seizures (seizures that start in one area of the brain) in patients with epilepsy aged 4 years and older. Both the tablet and oral suspension forms carry this indication. Perampanel tablets and oral suspension are also approved as add-on (adjunctive) therapy for primary generalized tonic-clonic seizures (grand mal seizures involving the whole brain at once) in patients with epilepsy aged 12 years and older. Fycompa oral suspension and tablet share both indications.

Epilepsy studied, not established Dimethylglycine (dmg) has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows
Dimethylglycine (dmg) for epilepsy
It is unclear if oral dimethylglycine is beneficial in patients with frequent generalized or myoclonic seizures.
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 Perampanel on your own; if you are taking Dimethylglycine (dmg) 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 Perampanel page
“Perampanel (Fycompa) is a seizure medicine that already causes drowsiness and dizziness on its own, which is why I treat this list of 230 interacting supplements with real care. Most entries do one of two things: they add to its sedating effect, as alcohol and kava do, or they change how the liver 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. Dimethylglycine (dmg) 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 Dimethylglycine (dmg) reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Dimethylglycine (dmg) and Perampanel records this page draws on were last updated June 22, 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.
