Clove and Disopyramide Phosphate

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Disopyramide Phosphate

Disopyramide Phosphate falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Clove interacts with.

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.
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 idea behind this pairing. Your body clears disopyramide using a liver enzyme called CYP3A4. In lab studies, eugenol (the main compound in clove) can slow that enzyme down. If that happened in a person, it could let disopyramide build up to higher levels than expected.

Why does that matter? Disopyramide is a heart rhythm medicine with a narrow safety window, so even modest increases can be a problem. Higher levels could mean more of its known side effects, like dry mouth, blurry vision, trouble urinating, constipation, low blood pressure, or rhythm changes. The good news: this is only theoretical and based on test-tube work, not real people. Cooking with clove almost certainly won't matter. If you're thinking about concentrated clove oil or capsules, please check with your pharmacist or doctor first.

From our pharmacist’s overview on the Disopyramide Phosphate page

“Grapefruit is the first thing I would set aside on disopyramide phosphate (Norpace), a medicine that steadies dangerous heart rhythms, because grapefruit juice can push the drug's blood level up. That pattern dominates the page, since 121 of the 169 flagged ingredients act on the same liver enzyme, CYP3A4, raising the drug's level or,…”

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 Disopyramide

What Is Disopyramide Used For?

Brand names: Norpace CR, Norpace

Disopyramide — available as Disopyramide Phosphate, Norpace, and Norpace CR — is indicated for the treatment of documented ventricular arrhythmias, such as sustained ventricular tachycardia (a fast, dangerous heart rhythm originating in the lower chambers), that a physician judges to be life-threatening.

Because of its potential to worsen heart rhythm problems, it is generally not recommended for lesser arrhythmias, and it should not be used to treat ventricular premature contractions (extra heartbeats) that cause no symptoms. Treatment is typically started in a hospital setting.
