Glycerol + Felbamate
Felbamate brand name: Felbatol.
We found no known interaction between Glycerol 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.
Glycerol 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 Glycerol 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 Glycerol 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.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
See Every Supplement That Interacts With Felbamate
This page covers Glycerol 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.
- Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Glycerol reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Glycerol 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 Glycerol
What is Glycerol?
- Constipation (laxative)
- Dry skin (moisturizer)
- Dry, irritated eyes
- Sore throat (in lozenges)
- Athletic hydration and endurance
- Cough and chest congestion (in some syrups)
Glycerol (glycerin) is a sweet, syrupy compound made naturally in the body and widely used in foods, skin products, and medicines. It is well established as a laxative and a skin and eye moisturizer, while its use to boost athletic performance is less proven and is banned in sports because it can mask other substances. For most people it is well tolerated, but check with a pharmacist before using it medicinally, especially if you are pregnant, breastfeeding, or have a health condition.
Not applicable (a simple chemical compound, also made naturally in the body) · Oral liquid, syrup, rectal suppositories, enemas, eye drops, skin creams and lotions, throat lozenges, sports drinks
An interaction check asks whether these two react with each other — it does not ask whether Glycerol is a good idea for someone in your situation. Here is what our Glycerol record says about it on its own.
Glycerol: dosing
There is no single "standard" dose of glycerol because it depends entirely on the product and the reason for use. A glycerin suppository for constipation, an oral laxative solution, an eye drop, and a sports hydration drink all use very different amounts.The safest approach is to follow the directions on the product label or your healthcare provider's instructions.

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 Glycerol — it is a separate effect of the medicine, and it is a reason some people are advised to supplement rather than to avoid one:
