The bottom line No known interaction

We found no known interaction between Black Nightshade 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.

Black Nightshade 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 Black Nightshade 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 Black Nightshade 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.

  • Low magnesium Worth acting on

See Every Supplement That Interacts With Felbamate

This page covers Black Nightshade 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.”

About Black Nightshade

What is Black Nightshade?

Black Nightshade
  • Digestive complaints
  • Skin conditions
  • Inflammation
  • Fever
  • Liver support (traditional)

Black nightshade is a wild plant whose cooked ripe berries and leaves are eaten as food in some cultures, but unripe berries and green parts can be poisonous. Human evidence for any health benefit is very limited, and the risk of toxicity is real. Do not use it as a supplement without medical guidance, and avoid it during pregnancy and breastfeeding.

Solanum nigrum · Solanaceae · Leaves, berries (ripe), and whole plant · Cooked leafy greens, fruit, traditional decoctions, dried herb, extracts

An interaction check asks whether these two react with each other — it does not ask whether Black Nightshade is a good idea for someone in your situation. Here is what our Black Nightshade record says about it on its own.

Black Nightshade: dosing

There is no established or standardized safe dose of black nightshade as a supplement. When it comes to wild plants, never guess at an amount or forage your own to use as medicine.

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.
