Clove and Perampanel

These two interact in 3 distinct ways. Each one is explained separately below.

Why Are There 3 Interactions?

Clove interacts with whole categories of medication. Perampanel falls into 3 of those categories, so it can interact with Clove in 3 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

1 of 3

Why this applies to Perampanel

Perampanel falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Clove interacts with.

Theoretically, concomitant use of clove may increase levels of drugs metabolized by CYP1A2.
In vitro research shows that eugenol, the principal constituent of clove, can inhibit CYP1A2 in a dose-dependent manner,. This effect has not been reported in humans.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the basic idea with clove and your Fycompa (perampanel). Your body relies on a liver enzyme called CYP1A2 to help clear perampanel out of your system. Lab studies suggest that eugenol, the main compound in clove, may slow that enzyme down. If that happened in people, perampanel could build up a bit higher than usual, which might bring on more of its typical side effects like drowsiness, dizziness, trouble walking steadily, or mood and behavior changes.

The honest part: this is only seen in test-tube research, not in actual patients, so it's theoretical. Sprinkling clove on your food almost certainly won't matter. Concentrated clove oil or supplements are the bigger question. Before using those regularly, just run it by your pharmacist or doctor.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 3

Perampanel also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

Theoretically, concomitant use of clove may increase levels of drugs metabolized by CYP3A4.
In vitro research shows that eugenol, the principal constituent of clove, can inhibit CYP3A4 in a dose-dependent manner. This effect has not been reported in humans.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for Perampanel (Fycompa): your liver clears it using an enzyme called CYP3A4. Clove's main compound, eugenol, has been shown in lab dish studies to slow that same enzyme down. If that happened in your body, your perampanel might clear a bit slower and build up, which could mean more of its usual side effects like dizziness, drowsiness, trouble with balance, or mood and irritability changes.

The good news: this is only seen in test-tube research, not in real people, so I wouldn't lose sleep over it. The pinch of clove in your food is a non-issue. Concentrated clove oil or supplements are where I'd be more cautious. Since perampanel affects your seizures, just check with your pharmacist or doctor before adding any clove product.

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES

Perampanel also falls under CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES.

Theoretically, concomitant use of clove may increase levels of drugs metabolized by CYP2C9.
In vitro research shows that eugenol, the principal constituent of clove, inhibits CYP2C9 in a dose-dependent manner. This effect has not been reported in humans.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the quick version: your seizure medicine Perampanel is partly cleared by a liver enzyme called CYP2C9. In test-tube studies, eugenol (the main compound in clove) slowed that same enzyme down. If that happened in your body too, Perampanel could clear more slowly and build up a bit, which might mean more of its usual side effects like sleepiness, dizziness, trouble with balance, or mood and irritability changes.

The important caveat: this is only laboratory evidence, not something seen in real people, so it's theoretical. Normal cooking amounts of clove are very unlikely to matter. Concentrated clove oil or supplements are the bigger question mark. Before using those regularly, check with your pharmacist or doctor so your seizure control stays steady.

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 Clove

What is Clove?

Clove
  • Toothache and oral pain
  • Digestive upset
  • Antimicrobial and antifungal
  • Cough and respiratory complaints
  • Flavoring in food and drinks

Clove is a common cooking spice that is also used in traditional medicine, especially as a topical numbing agent for tooth pain thanks to its main compound, eugenol. Food amounts are generally safe, but concentrated clove oil and supplements can be irritating or toxic if overused, and human evidence for most health claims is limited. Talk to your pharmacist or doctor before using clove medicinally, especially in children or during pregnancy.

About Perampanel

What Is Perampanel Used For?

Perampanel — available as Fycompa and in generic forms — is used to treat partial-onset seizures (seizures that start in one area of the brain) in patients with epilepsy aged 4 years and older. Both the tablet and oral suspension forms carry this indication.

Perampanel tablets and oral suspension are also approved as add-on (adjunctive) therapy for primary generalized tonic-clonic seizures (grand mal seizures involving the whole brain at once) in patients with epilepsy aged 12 years and older. Fycompa oral suspension and tablet share both indications.
