Clove and dabigatran

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

Minor

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to dabigatran

dabigatran falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Clove interacts with.

Theoretically, clove oil may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Laboratory research suggests that eugenol, a constituent of clove, has antiplatelet activity. This interaction has not been reported in humans.
Severity Minor Likelihood Unlikely Evidence D

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

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

Here's the simple version. Dabigatran (Pradaxa) is already a blood thinner, and clove contains a compound called eugenol that, in lab studies, seems to make platelets a little less sticky. Put those two ideas together and you can see the worry: on paper, clove could nudge your bleeding risk up a notch when added to dabigatran.

That said, this is theoretical. It comes from test-tube research, not from real people, and it's rated minor and unlikely. The clove in your food is not something to lose sleep over. Concentrated clove oil or capsules are a different story, since they pack far more eugenol. With dabigatran, watch for easy bruising, nosebleeds, bleeding gums, or pink urine, and check with your pharmacist before using clove as a supplement.

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 Dabigatran

What Is Dabigatran Used For?

Brand names: Pradaxa, Pradax

Dabigatran etexilate capsules are used in adults to reduce the risk of stroke and dangerous blood clots in people with non-valvular atrial fibrillation (an irregular heart rhythm not caused by a heart valve problem). They are also used to treat deep venous thrombosis (DVT — a blood clot in a deep vein) and pulmonary embolism (PE — a blood clot in the lungs), to lower the risk of those clots coming back, and to prevent DVT and PE in adults who have had hip replacement surgery.

In children ages 8 to under 18, dabigatran etexilate capsules are used to treat venous thromboembolic events (VTE — blood clots in the veins) and to reduce the risk of those clots recurring. Pradaxa Oral Pellets — a separate formulation — are indicated for the treatment and prevention of recurrent VTE in younger children ages 3 months to under 12 years.
