Clove and Duloxetine

Here is the interaction we found between these two, with the evidence behind it.

Moderate

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES

Why this applies to Duloxetine

Duloxetine falls under CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES — the group Clove interacts with.

Theoretically, concomitant use of clove may increase levels of drugs metabolized by CYP2D6.
In vitro research shows that eugenol, the principal constituent of clove, can inhibit CYP2D6 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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the basic idea: your body uses an enzyme called CYP2D6 to help break down duloxetine. Lab studies suggest that eugenol, the main oil in clove, may slow that enzyme down. If it did the same thing in people, your duloxetine could clear more slowly and build up a bit, which might mean stronger side effects like nausea, dizziness, dry mouth, sleepiness, headache, or feeling jittery.

The important part: this is only seen in test-tube studies, not in actual patients, so it's theoretical for now. Sprinkling clove on your food is very unlikely to cause any trouble. Concentrated clove oil or supplements are a different story. If you're thinking about using clove medicinally while on duloxetine, just run it by your pharmacist or doctor first.

  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).

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.
