Higenamine + Felbamate
Felbamate brand name: Felbatol.
We found no known interaction between Higenamine 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. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.
Higenamine 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 Higenamine 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.
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.
Higenamine safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Felbamate
Interactions in our licensed database are recorded against drug classes, not just single drug names. Felbamate is filed under 8 classifications — including anticonvulsants, cytochrome p450 2c19 (cyp2c19) inhibitors, qt interval-prolonging drugs. Higenamine has documented interactions with 5 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), cytochrome p450 2d6 (cyp2d6) substrates (moderate) and cytochrome p450 3a4 (cyp3a4) substrates (moderate) — and none of Felbamate’s classifications are among them.
Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.
Higenamine Does Interact With Other Medications
Higenamine has 891 moderate known drug interactions in our database — Felbamate isn’t one of them. If you take anything else, check it against the full list below.

See Every Supplement That Interacts With Felbamate
This page covers Higenamine 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.”

- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions.
- Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Higenamine reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Higenamine and Felbamate records this page draws on were last updated July 10, 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 Higenamine
What is Higenamine?
- Weight loss and fat burning
- Pre-workout energy and performance
- Appetite suppression
- Athletic stimulant
- Traditional medicine remedies
Higenamine is a plant-based stimulant compound added to many weight-loss and pre-workout supplements, but there is very little human evidence that it works and real concerns about heart and blood pressure effects. It is banned in sports by the World Anti-Doping Agency (WADA), and product labels often list inaccurate amounts, so most people should approach it with caution and talk to a pharmacist or doctor first.
Plant-derived alkaloid (found in plants such as Aconitum, Nelumbo/lotus, and Annona species) · Capsules, tablets, powders, pre-workout and fat-burner blends
An interaction check asks whether these two react with each other — it does not ask whether Higenamine is a good idea for someone in your situation. Here is what our Higenamine record says about it on its own.
Higenamine: dosing
There is no established or proven safe dose of higenamine. Supplement products vary widely, and testing has shown that the labeled amount is often unreliable, so it is hard to know how much you are actually taking.Because of this uncertainty and the potential heart effects, we do not recommend a specific dose.

About Felbamate
What Is Felbamate Used For?
Brand name: Felbatol
Felbamate is not a first-line seizure medication. It is used only when a person's epilepsy has not responded well enough to other treatments and the seizures are severe enough that the serious risks of this drug are considered acceptable.
In adults, felbamate can be used alone or alongside other antiepileptic drugs (AEDs) to treat partial seizures (seizures that start in one part of the brain), with or without spreading to become a full seizure. In children, felbamate is used as an add-on treatment for both partial and generalized seizures linked to Lennox-Gastaut syndrome, a severe form of childhood epilepsy. Felbatol is specifically labeled for these uses in both adults and children.

Felbamate Is Linked to Lower Levels of One Nutrient
Natural Medicines records Felbamate as a medicine that can lower these. This is not an interaction with Higenamine — it is a separate effect of the medicine, and it is a reason some people are advised to supplement rather than to avoid one:
