Drug & supplement interaction

Tomato + Perampanel

Perampanel brand name: Fycompa.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Tomato 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. 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.

Tomato 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 Tomato 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 Tomato 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 to actually watch for

No Interaction Found — But Data Suggests Tomato and Perampanel May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • Dizziness / Headache reported in 5.3% of FDA reports for Perampanel Additional detail

    Perampanel

    Listed in the ADVERSE REACTIONS section of the FDA label for Perampanel. Read the label on DailyMed ›

Reported for Tomato but not commonly for Perampanel: a slow heartbeat and diarrhea.

Effects for Perampanel come from the ADVERSE REACTIONS section of its FDA label; effects for Tomato come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 7,347 voluntary FDA FAERS reports for Perampanel that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

See Every Supplement That Interacts With Perampanel

This page covers Tomato only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Perampanel page lists 230 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), Beer (major), Gamma-hydroxybutyrate (ghb) (major) and Grapefruit (major).

By severity: 9 major · 175 moderate · 46 minor.

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.”

About Tomato

What is Tomato?

  • Heart health support
  • Prostate health
  • Antioxidant support
  • Skin protection from sun damage
  • General nutrition

Tomato is a common food rich in vitamins, potassium, and the antioxidant lycopene, and eating it as part of a balanced diet is healthy for most people. Concentrated tomato or lycopene supplements are marketed for heart and prostate health, but the evidence is mixed and far from proven. Talk to your pharmacist or doctor before using high-dose supplements, especially if you are pregnant or have a medical condition.

Solanum lycopersicum · Solanaceae · Fruit (and extracts such as lycopene from the fruit and skin) · Whole fruit, juice, paste, tomato extract capsules, lycopene supplements

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

Tomato: dosing

There is no official standardized dose of tomato or lycopene supplements, and a proven effective amount has not been established. Tomatoes are best enjoyed simply as part of a balanced diet.If you choose to use a tomato extract or lycopene supplement, follow the directions on the product label and do not exceed the recommended amount.

Taking Tomato and Perampanel Together: Common Questions

Is it safe to take Tomato with Perampanel?
We do not list a known interaction between Tomato and Perampanel. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Tomato and Perampanel have any of the same side effects?
Yes — our sources link each of them separately to 3 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Does Perampanel interact with any supplements?
Yes. Perampanel has documented interactions with 230 supplements in our database — Tomato is not one of them. The Perampanel interaction page linked on this page lists every one, ranked by severity.
