Codonopsis and dabigatran

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to dabigatran

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

Theoretically, codonopsis liquor might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
A small clinical study in adults with coronary heart disease shows that consuming Codonopsis pilosula liquor for 4 weeks inhibits platelet aggregation but does not affect tissue-type plasminogen activator (t-PA) or plasminogen activator inhibitor (PAI).
Severity Moderate Likelihood Possible Evidence B

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 thing to keep in mind with dabigatran (Pradaxa): it's already a powerful blood thinner, so anything else that nudges your blood toward thinner is worth a second look. A small study found that codonopsis liquor made platelets a little less sticky on their own. Stack that mild effect on top of dabigatran, and you could, in theory, raise your bleeding risk a bit.

What might that look like in real life? Easy bruising, nosebleeds, bleeding gums, or longer bleeding from small cuts. This is mostly theoretical and based on weak evidence, so don't panic. Food-sized amounts are far less likely to matter than concentrated supplements or codonopsis liquor. Before combining them, please run it by your pharmacist or doctor first.

About Codonopsis

What is Codonopsis?

  • Fatigue and low energy
  • Digestive support and poor appetite
  • Immune support
  • General tonic ('qi' tonic in Traditional Chinese Medicine)
  • Cough and weakness during recovery from illness

Codonopsis (often called 'dang shen') is a root long used in Traditional Chinese Medicine as a gentle energy and digestive tonic, frequently as a milder substitute for ginseng. Human research is very limited, so its benefits are not well proven. It appears reasonably well tolerated in food-like amounts, but you should talk with a pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or have a health condition.

About Dabigatran

What Is Dabigatran Used For?

Brand names: Pradaxa, Pradax

Dabigatran etexilate capsules are approved for adults to reduce the risk of stroke and systemic embolism (blood clots traveling through the body) in non-valvular atrial fibrillation (an irregular heart rhythm not caused by a heart valve problem). Capsules are also used to treat deep vein thrombosis (DVT — a blood clot in a deep vein, usually the leg) and pulmonary embolism (PE — a clot in the lungs), to prevent those clots from coming back, and to prevent DVT and PE in adults who have had hip replacement surgery.

For children, the capsule form is approved for treating VTE (venous thromboembolism — blood clots in veins) and reducing recurrence in patients aged 8 to under 18. Pradaxa Oral Pellets are approved specifically for children aged 3 months to under 12 years for the same treatment and recurrence-prevention purposes.
