Dimethylglycine (dmg) + Felbamate
Felbamate brand name: Felbatol.
We found no known interaction between Dimethylglycine (dmg) and Felbamate 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 Felbamate
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 Felbamate 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 Felbamate, 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 Felbamate 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. Felbamate 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.
Felbamate is prescribed for: Felbamate is not a first-choice seizure medicine. It is reserved for people whose epilepsy is severe and who have not responded well to other treatments. If those criteria are met, the patient has been fully told about the risks, and has given written acknowledgment, it can be used for: Partial seizures (with or without generalization) in adults, alone or added to other medicines Partial and generalized seizures linked to Lennox-Gastaut syndrome in children, as an add-on medicine This applies to Felbatol and to felbamate oral suspension and tablets.

-
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 Felbamate 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.
See Every Supplement That Interacts With Felbamate
This page covers Dimethylglycine (dmg) only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Felbamate page lists 172 supplements it has a documented interaction with, worst first, each one explained.
The most serious there right now: 1,4-butanediol (major), Activated Charcoal (major), American Hellebore (major), Arsenic (major) and Beer (major).
By severity: 14 major · 141 moderate · 17 minor.
From our pharmacist’s overview on the Felbamate page
“Felbamate (Felbatol) is a seizure medicine usually reserved for epilepsy that other drugs have failed to control, in part because it can stress the liver on its own. That history is why its 172 supplement and herbal interactions deserve real vigilance, starting with the 14 rated major.”

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 27, 2026. The Dimethylglycine (dmg) and Felbamate 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.

What is Dimethylglycine (dmg)?
- Athletic performance and energy

Dimethylglycine (DMG) is a substance made naturally in the body and found in small amounts in foods. It is marketed for energy, athletic performance, autism, and immune support, but solid human evidence for most of these uses is limited. It appears generally well tolerated in short-term use, but talk with your pharmacist or doctor before trying it.
